The latter accepts only table_reference, not a list of them\ninside a pair of parentheses.\n\nThis is a conservative extension if we consider each comma in a list of\ntable_reference items as equivalent to an inner join. For example:\n\nSELECT * FROM t1 LEFT JOIN (t2, t3, t4)\n                 ON (t2.a=t1.a AND t3.b=t1.b AND t4.c=t1.c)\n\nis equivalent to:\n\nSELECT * FROM t1 LEFT JOIN (t2 CROSS JOIN t3 CROSS JOIN t4)\n                 ON (t2.a=t1.a AND t3.b=t1.b AND t4.c=t1.c)\n\nIn MySQL, CROSS JOIN is a syntactic equivalent to INNER JOIN (they can\nreplace each other). In standard SQL, they are not equivalent. INNER\nJOIN is used with an ON clause, CROSS JOIN is used otherwise.\n\nIn general, parentheses can be ignored in join expressions containing\nonly inner join operations. MySQL also supports nested joins (see\nhttp://dev.mysql.com/doc/refman/5.1/en/nested-join-optimization.html).\n\nIndex hints can be specified to affect how the MySQL optimizer makes\nuse of indexes.

A session can acquire or\nrelease locks only for itself. One session cannot acquire locks for\nanother session or release locks held by another session.\n\nLOCK TABLES acquires table locks for the current thread. It locks base\ntables or views. (For view locking, LOCK TABLES adds all base tables\nused in the view to the set of tables to be locked and locks them\nautomatically.) To use LOCK TABLES, you must have the LOCK TABLES\nprivilege, and the SELECT privilege for each object to be locked.\n\nMySQL enables client sessions to acquire table locks explicitly Locks\nmay be used to emulate transactions or to get more speed when updating\ntables. This is explained in more detail later in this section.\n\nUNLOCK TABLES explicitly releases any table locks held by the current\nthread. Another use for UNLOCK TABLES is to release the global read\nlock acquired with FLUSH TABLES WITH READ LOCK. (You can lock all\ntables in all databases with a read lock with the FLUSH TABLES WITH\nREAD LOCK statement. See [HELP FLUSH]. This is a very convenient way to\nget backups if you have a file system such as Veritas that can take\nsnapshots in time.)\n\nThe following discussion applies only to non-TEMPORARY tables. LOCK\nTABLES is allowed (but ignored) for a TEMPORARY table. The table can be\naccessed freely by the session within which it was created, regardless\nof what other locking may be in effect. No lock is necessary because no\nother session can see the table.\n\nThe following general rules apply to acquisition and release of locks\nby a given thread:\n\no Table locks are acquired with LOCK TABLES.\n\no If the LOCK TABLES statement must wait due to locks held by other\n  threads on any of the tables, it blocks until all locks can be\n  acquired.\n\no Table locks are released explicitly with UNLOCK TABLES.\n\no Table locks are released implicitly under these conditions:\n\n  o LOCK TABLES releases any table locks currently held by the thread\n    before acquiring new locks.\n\n  o Beginning a transaction (for example, with START TRANSACTION)\n    implicitly performs an UNLOCK TABLES. (Additional information about\n    the interaction between table locking and transactions is given\n    later in this section.)\n\n  o If a client connection drops, the server releases table locks held\n    by the client. If the client reconnects, the locks will no longer\n    be in effect. In addition, if the client had an active transaction,\n    the server rolls back the transaction upon disconnect, and if\n    reconnect occurs, the new session begins with autocommit enabled.\n    For this reason, clients may wish to disable auto-reconnect. With\n    auto-reconnect in effect, the client is not notified if reconnect\n    occurs but any table locks or current transaction will have been\n    lost. With auto-reconnect disabled, if the connection drops, an\n    error occurs for the next statement issued. The client can detect\n    the error and take appropriate action such as reacquiring the locks\n    or redoing the transaction. See\n    http://dev.mysql.com/doc/refman/5.1/en/auto-reconnect.html.\n\n*Note*: If you use ALTER TABLE on a locked table, it may become\nunlocked. See\nhttp://dev.mysql.com/doc/refman/5.1/en/alter-table-problems.html.\n\nA table lock protects only against inappropriate reads or writes by\nother clients. The client holding the lock, even a read lock, can\nperform table-level operations such as DROP TABLE.

It is\nsubject to removal in a future version of MySQL.\n\nSince the current implementation of LOAD DATA FROM MASTER and LOAD\nTABLE FROM MASTER is very limited, these statements are deprecated in\nversions 4.1 of MySQL and above. We will introduce a more advanced\ntechnique (called "online backup") in a future version. That technique\nwill have the additional advantage of working with more storage\nengines.\n\nFor MySQL 5.1 and earlier, the recommended alternative solution to\nusing LOAD DATA FROM MASTER or LOAD TABLE FROM MASTER is using\nmysqldump or mysqlhotcopy. The latter requires Perl and two Perl\nmodules (DBI and DBD:mysql) and works for MyISAM and ARCHIVE tables\nonly. With mysqldump, you can create SQL dumps on the master and pipe\n(or copy) these to a mysql client on the slave. This has the advantage\nof working for all storage engines, but can be quite slow, since it\nworks using SELECT.\n\nThis statement takes a snapshot of the master and copies it to the\nslave. It updates the values of MASTER_LOG_FILE and MASTER_LOG_POS so\nthat the slave starts replicating from the correct position. Any table\nand database exclusion rules specified with the --replicate-*-do-* and\n--replicate-*-ignore-* options are honored. --replicate-rewrite-db is\nnot taken into account because a user could use this option to set up a\nnon-unique mapping such as --replicate-rewrite-db="db1->db3" and\n--replicate-rewrite-db="db2->db3", which would confuse the slave when\nloading tables from the master.\n\nUse of this statement is subject to the following conditions:\n\no It works only for MyISAM tables. Attempting to load a non-MyISAM\n  table results in the following error:\n\nERROR 1189 (08S01): Net error reading from master\n\no It acquires a global read lock on the master while taking the\n  snapshot, which prevents updates on the master during the load\n  operation.\n\nIf you are loading large tables, you might have to increase the values\nof net_read_timeout and net_write_timeout on both the master and slave\nservers. See\nhttp://dev.mysql.com/doc/refman/5.1/en/server-system-variables.html.\n\nNote that LOAD DATA FROM MASTER does not copy any tables from the mysql\ndatabase. This makes it easy to have different users and privileges on\nthe master and the slave.\n\nTo use LOAD DATA FROM MASTER, the replication account that is used to\nconnect to the master must have the RELOAD and SUPER privileges on the\nmaster and the SELECT privilege for all master tables you want to load.\nAll master tables for which the user does not have the SELECT privilege\nare ignored by LOAD DATA FROM MASTER. This is because the master hides\nthem from the user: LOAD DATA FROM MASTER calls SHOW DATABASES to know\nthe master databases to load, but SHOW DATABASES returns only databases\nfor which the user has some privilege. See [HELP SHOW DATABASES]. On\nthe slave side, the user that issues LOAD DATA FROM MASTER must have\nprivileges for dropping and creating the databases and tables that are\ncopied.\n\nURL: http://dev.mysql.com/doc/refman/5.1/en/load-data-from-master.html\n\n', '', 'http://dev.mysql.com/doc/refman/5.1/en/load-data-from-master.html'),

If you have a lock obtained with GET_LOCK(), it is released when\nyou execute RELEASE_LOCK(), execute a new GET_LOCK(), or your\nconnection terminates (either normally or abnormally). Locks obtained\nwith GET_LOCK() do not interact with transactions. That is, committing\na transaction does not release any such locks obtained during the\ntransaction.\n\nThis function can be used to implement application locks or to simulate\nrecord locks. Names are locked on a server-wide basis. If a name has\nbeen locked by one client, GET_LOCK() blocks any request by another\nclient for a lock with the same name. This allows clients that agree on\na given lock name to use the name to perform cooperative advisory\nlocking. But be aware that it also allows a client that is not among\nthe set of cooperating clients to lock a name, either inadvertently or\ndeliberately, and thus prevent any of the cooperating clients from\nlocking that name. One way to reduce the likelihood of this is to use\nlock names that are database-specific or application-specific.

The default is 60. The number of reconnection attempts is\nlimited by the --master-retry-count server option; for more\ninformation, see\nhttp://dev.mysql.com/doc/refman/5.1/en/replication-options.html.\n\nThe SSL options (MASTER_SSL, MASTER_SSL_CA, MASTER_SSL_CAPATH,\nMASTER_SSL_CERT, MASTER_SSL_KEY, MASTER_SSL_CIPHER), and\nMASTER_SSL_VERIFY_SERVER_CERT can be changed even on slaves that are\ncompiled without SSL support. They are saved to the master.info file,\nbut are ignored unless you use a server that has SSL support enabled.\n\nIf you don''t specify a given parameter, it keeps its old value, except\nas indicated in the following discussion. For example, if the password\nto connect to your MySQL master has changed, you just need to issue\nthese statements to tell the slave about the new password:\n\nSTOP SLAVE; -- if replication was running\nCHANGE MASTER TO MASTER_PASSWORD=''new3cret'';\nSTART SLAVE; -- if you want to restart replication\n\nThere is no need to specify the parameters that do not change (host,\nport, user, and so forth).\n\nMASTER_HOST and MASTER_PORT are the host name (or IP address) of the\nmaster host and its TCP/IP port.\n\nThe next two options are available only in MySQL Cluster NDB 6.3 and\n6.4; they are not supported in mainline MySQL 5.1:\n\no MASTER_BIND is for use on replication slaves having multiple network\n  interfaces, and determines which of the slave''s network interfaces is\n  chosen for connecting to the master. It is also possible to determine\n  which network interface is to be used in such cases by starting the\n  slave mysqld process with the --master-bind option.\n\n  The ability to bind a replication slave to specific network interface\n  was added in MySQL Cluster NDB 6.3.4.\n\no MASTER_HEARTBEAT_PERIOD is used to set the interval in seconds\n  between replication heartbeats. Whenever the master''s binlog is\n  updated with an event, the waiting period for the next heartbeat is\n  reset. interval is a decimal value having the range 0 to 4294967\n  seconds and a resolution to hundredths of a second; the smallest\n  nonzero value is 0.001. Heartbeats are sent by the master only if\n  there are no unsent events in the binlog file for a period longer\n  than interval.\n\n  Setting interval to 0 disables heartbeats altogether. The default\n  value for interval is equal to the value of slave_net_timeout divided\n  by 2.\n\n  *Note*: Setting @@global.slave_net_timeout to a value less than that\n  of the current heartbeat interval results in a warning being issued.\n\n  Issuing RESET SLAVE resets the heartbeat interval to the default.\n\n  MASTER_HEARTBEAT_PERIOD was added in MySQL Cluster NDB 6.3.4.\n\n*Note*: Replication cannot use Unix socket files. You must be able to\nconnect to the master MySQL server using TCP/IP.\n\nIf you specify MASTER_HOST or MASTER_PORT, the slave assumes that the\nmaster server is different from before (even if you specify a host or\nport value that is the same as the current value.) In this case, the\nold values for the master binary log name and position are considered\nno longer applicable, so if you do not specify MASTER_LOG_FILE and\nMASTER_LOG_POS in the statement, MASTER_LOG_FILE='''' and\nMASTER_LOG_POS=4 are silently appended to it.\n\nMASTER_LOG_FILE and MASTER_LOG_POS are the coordinates at which the\nslave I/O thread should begin reading from the master the next time the\nthread starts. If you specify either of them, you cannot specify\nRELAY_LOG_FILE or RELAY_LOG_POS. If neither of MASTER_LOG_FILE or\nMASTER_LOG_POS are specified, the slave uses the last coordinates of\nthe slave SQL thread before CHANGE MASTER TO was issued. This ensures\nthat there is no discontinuity in replication, even if the slave SQL\nthread was late compared to the slave I/O thread, when you merely want\nto change, say, the password to use.\n\nCHANGE MASTER TO deletes all relay log files and starts a new one,\nunless you specify RELAY_LOG_FILE or RELAY_LOG_POS. In that case, relay\nlogs are kept; the relay_log_purge global variable is set silently to\n0.\n\nCHANGE MASTER TO is useful for setting up a slave when you have the\nsnapshot of the master and have recorded the log and the offset\ncorresponding to it. After loading the snapshot into the slave, you can\nrun CHANGE MASTER TO MASTER_LOG_FILE=''log_name_on_master'',\nMASTER_LOG_POS=log_offset_on_master on the slave.\n\nThe following example changes the master and master''s binary log\ncoordinates. This is used when you want to set up the slave to\nreplicate the master:\n\nCHANGE MASTER TO\n  MASTER_HOST=''master2.mycompany.com'',\n  MASTER_USER=''replication'',\n  MASTER_PASSWORD=''bigs3cret'',\n  MASTER_PORT=3306,\n  MASTER_LOG_FILE=''master2-bin.001'',\n  MASTER_LOG_POS=4,\n  MASTER_CONNECT_RETRY=10;\n\nThe next example shows an operation that is less frequently employed.\nIt is used when the slave has relay logs that you want it to execute\nagain for some reason. To do this, the master need not be reachable.\nYou need only use CHANGE MASTER TO and start the SQL thread (START\nSLAVE SQL_THREAD):\n\nCHANGE MASTER TO\n  RELAY_LOG_FILE=''slave-relay-bin.006'',\n  RELAY_LOG_POS=4025;\n\nURL: http://dev.mysql.com/doc/refman/5.1/en/change-master-to.html\n\n', '', 'http://dev.mysql.com/doc/refman/5.1/en/change-master-to.html'),

One data file is\ncreated and added to the tablespace using this statement. Additional\ndata files may be added to the tablespace by using the ALTER TABLESPACE\nstatement (see [HELP ALTER TABLESPACE]). For rules covering the naming\nof tablespaces, see\nhttp://dev.mysql.com/doc/refman/5.1/en/identifiers.html.\n\nA log file group of one or more UNDO log files must be assigned to the\ntablespace to be created with the USE LOGFILE GROUP clause.\nlogfile_group must be an existing log file group created with CREATE\nLOGFILE GROUP (see\nhttp://dev.mysql.com/doc/refman/5.1/en/create-logfile-group.html).\nMultiple tablespaces may use the same log file group for UNDO logging.\n\nThe EXTENT_SIZE sets the size, in bytes, of the extents used by any\nfiles belonging to the tablespace. The default value is 1M. The minimum\nsize is 32K, and theoretical maximum is 2G, although the practical\nmaximum size depends on a number of factors. In most cases, changing\nthe extent size does not have any measurable effect on performance, and\nthe default value is recommended for all but the most unusual\nsituations.\n\nAn extent is a unit of disk space allocation. One extent is filled with\nas much data as that extent can contain before another extent is used.\nIn theory, up to 65,535 (64K) extents may used per data file; however,\nthe recommended maximum is 32,768 (32K). The recommended maximum size\nfor a single data file is 32G --- that is, 32K extents x 1 MB per\nextent. In addition, once an extent is allocated to a given partition,\nit cannot be used to store data from a different partition; an extent\ncannot store data from more than one partition. This means, for example\nthat a tablespace having a single datafile whose INITIAL_SIZE is 256 MB\nand whose EXTENT_SIZE is 128M has just two extents, and so can be used\nto store data from at most two different disk data table partitions.\n\nYou can see how many extents remain free in a given data file by\nquerying the INFORMATION_SCHEMA.FILES table, and so derive an estimate\nfor how much space remains free in the file. For further discussion and\nexamples, see http://dev.mysql.com/doc/refman/5.1/en/files-table.html.\n\nThe INITIAL_SIZE parameter sets the data file''s total size in bytes.\nOnce the file has been created, its size cannot be changed; however,\nyou can add more data files to the tablespace using ALTER TABLESPACE\n... ADD DATAFILE. See [HELP ALTER TABLESPACE].\n\nINITIAL_SIZE is optional; its default value is 128M.\n\nOn 32-bit systems, the maximum supported value for INITIAL_SIZE is 4G.\n(Bug#29186 (http://bugs.mysql.com/29186))\n\nWhen setting EXTENT_SIZE or INITIAL_SIZE (either or both), you may\noptionally follow the number with a one-letter abbreviation for an\norder of magnitude, similar to those used in my.cnf. Generally, this is\none of the letters M (for megabytes) or G (for gigabytes).\n\nAUTOEXTEND_SIZE, MAX_SIZE, NODEGROUP, WAIT, and COMMENT are parsed but\nignored, and so have no effect in MySQL 5.1. These options are intended\nfor future expansion.\n\nThe ENGINE parameter determines the storage engine which uses this\ntablespace, with engine_name being the name of the storage engine. In\nMySQL 5.1, engine_name must be one of the values NDB or NDBCLUSTER.\n\nWhen CREATE TABLESPACE is used with ENGINE = NDB, a tablespace and\nassociated data file are created on each Cluster data node. You can\nverify that the data files were created and obtain information about\nthem by querying the INFORMATION_SCHEMA.FILES table. For example:\n\nmysql> SELECT LOGFILE_GROUP_NAME, FILE_NAME, EXTRA \n    -> FROM INFORMATION_SCHEMA.FILES\n    -> WHERE TABLESPACE_NAME = ''newts'' AND FILE_TYPE = ''DATAFILE'';\n+--------------------+-------------+----------------+\n| LOGFILE_GROUP_NAME | FILE_NAME   | EXTRA          |\n+--------------------+-------------+----------------+\n| lg_3               | newdata.dat | CLUSTER_NODE=3 |\n| lg_3               | newdata.dat | CLUSTER_NODE=4 |\n+--------------------+-------------+----------------+\n2 rows in set (0.01 sec)\n\n(See http://dev.mysql.com/doc/refman/5.1/en/files-table.html.)\n\nCREATE TABLESPACE was added in MySQL 5.1.6.

For a\nworkaround, see\nhttp://dev.mysql.com/doc/refman/5.1/en/insert-on-duplicate.html.\n\nThe currently executing statement does not affect the value of\nLAST_INSERT_ID(). Suppose that you generate an AUTO_INCREMENT value\nwith one statement, and then refer to LAST_INSERT_ID() in a\nmultiple-row INSERT statement that inserts rows into a table with its\nown AUTO_INCREMENT column. The value of LAST_INSERT_ID() will remain\nstable in the second statement; its value for the second and later rows\nis not affected by the earlier row insertions. (However, if you mix\nreferences to LAST_INSERT_ID() and LAST_INSERT_ID(expr), the effect is\nundefined.)\n\nIf the previous statement returned an error, the value of\nLAST_INSERT_ID() is undefined. For transactional tables, if the\nstatement is rolled back due to an error, the value of LAST_INSERT_ID()\nis left undefined. For manual ROLLBACK, the value of LAST_INSERT_ID()\nis not restored to that before the transaction; it remains as it was at\nthe point of the ROLLBACK.\n\nWithin the body of a stored routine (procedure or function) or a\ntrigger, the value of LAST_INSERT_ID() changes the same way as for\nstatements executed outside the body of these kinds of objects. The\neffect of a stored routine or trigger upon the value of\nLAST_INSERT_ID() that is seen by following statements depends on the\nkind of routine:\n\no If a stored procedure executes statements that change the value of\n  LAST_INSERT_ID(), the changed value will be seen by statements that\n  follow the procedure call.\n\no For stored functions and triggers that change the value, the value is\n  restored when the function or trigger ends, so following statements\n  will not see a changed value.\n\nURL: http://dev.mysql.com/doc/refman/5.1/en/information-functions.html\n\n', '', 'http://dev.mysql.com/doc/refman/5.1/en/information-functions.html'),

By default, a routine is\nassociated with the default database. To associate the routine\nexplicitly with a given database, specify the name as db_name.sp_name\nwhen you create it.\n\nThe CREATE FUNCTION statement is also used in MySQL to support UDFs\n(user-defined functions). See\nhttp://dev.mysql.com/doc/refman/5.1/en/adding-functions.html. A UDF can\nbe regarded as an external stored function. However, do note that\nstored functions share their namespace with UDFs. See\nhttp://dev.mysql.com/doc/refman/5.1/en/function-resolution.html, for\nthe rules describing how the server interprets references to different\nkinds of functions.\n\nWhen the routine is invoked, an implicit USE db_name is performed (and\nundone when the routine terminates). The causes the routine to have the\ngiven default database while it executes. USE statements within stored\nroutines are disallowed.\n\nWhen a stored function has been created, you invoke it by referring to\nit in an expression. The function returns a value during expression\nevaluation. When a stored procedure has been created, you invoke it by\nusing the CALL statement (see [HELP CALL]).\n\nTo execute the CREATE PROCEDURE or CREATE FUNCTION statement, it is\nnecessary to have the CREATE ROUTINE privilege. By default, MySQL\nautomatically grants the ALTER ROUTINE and EXECUTE privileges to the\nroutine creator. See also\nhttp://dev.mysql.com/doc/refman/5.1/en/stored-routines-privileges.html.\nIf binary logging is enabled, the CREATE FUNCTION statement might also\nrequire the SUPER privilege, as described in\nhttp://dev.mysql.com/doc/refman/5.1/en/stored-programs-logging.html.\n\nThe DEFINER and SQL SECURITY clauses specify the security context to be\nused when checking access privileges at routine execution time, as\ndescribed later.\n\nIf the routine name is the same as the name of a built-in SQL function,\nyou must use a space between the name and the following parenthesis\nwhen defining the routine, or a syntax error occurs. This is also true\nwhen you invoke the routine later. For this reason, we suggest that it\nis better to avoid re-using the names of existing SQL functions for\nyour own stored routines.\n\nThe IGNORE_SPACE SQL mode applies to built-in functions, not to stored\nroutines. It is always allowable to have spaces after a routine name,\nregardless of whether IGNORE_SPACE is enabled.\n\nThe parameter list enclosed within parentheses must always be present.\nIf there are no parameters, an empty parameter list of () should be\nused. Parameter names are not case sensitive.\n\nEach parameter can be declared to use any valid data type, except that\nthe COLLATE attribute cannot be used.\n\nEach parameter is an IN parameter by default. To specify otherwise for\na parameter, use the keyword OUT or INOUT before the parameter name.\n\n*Note*: Specifying a parameter as IN, OUT, or INOUT is valid only for a\nPROCEDURE. (FUNCTION parameters are always regarded as IN parameters.)\n\nAn IN parameter passes a value into a procedure. The procedure might\nmodify the value, but the modification is not visible to the caller\nwhen the procedure returns. An OUT parameter passes a value from the\nprocedure back to the caller. Its initial value is NULL within the\nprocedure, and its value is visible to the caller when the procedure\nreturns. An INOUT parameter is initialized by the caller, can be\nmodified by the procedure, and any change made by the procedure is\nvisible to the caller when the procedure returns.\n\nFor each OUT or INOUT parameter, pass a user-defined variable in the\nCALL statement that invokes the procedure so that you can obtain its\nvalue when the procedure returns. If you are calling the procedure from\nwithin another stored procedure or function, you can also pass a\nroutine parameter or local routine variable as an IN or INOUT\nparameter.\n\nThe RETURNS clause may be specified only for a FUNCTION, for which it\nis mandatory. It indicates the return type of the function, and the\nfunction body must contain a RETURN value statement. If the RETURN\nstatement returns a value of a different type, the value is coerced to\nthe proper type. For example, if a function specifies an ENUM or SET\nvalue in the RETURNS clause, but the RETURN statement returns an\ninteger, the value returned from the function is the string for the\ncorresponding ENUM member of set of SET members.\n\nThe routine_body consists of a valid SQL procedure statement. This can\nbe a simple statement such as SELECT or INSERT, or it can be a compound\nstatement written using BEGIN and END. Compound statements can contain\ndeclarations, loops, and other control structure statements. The syntax\nfor these statements is described in\nhttp://dev.mysql.com/doc/refman/5.1/en/sql-syntax-compound-statements.h\ntml.\n\nMySQL allows routines to contain DDL statements, such as CREATE and\nDROP. MySQL also allows stored procedures (but not stored functions) to\ncontain SQL transaction statements such as COMMIT. Stored functions may\nnot contain statements that perform explicit or implicit commit or\nrollback. Support for these statements is not required by the SQL\nstandard, which states that each DBMS vendor may decide whether to\nallow them.\n\nStatements that return a result set cannot be used within a stored\nfunction. This includes SELECT statements that do not have an INTO\nvar_list clause and other statements such as SHOW, EXPLAIN, and CHECK\nTABLE. For statements that can be determined at function definition\ntime to return a result set, a Not allowed to return a result set from\na function error occurs (ER_SP_NO_RETSET). For statements that can be\ndetermined only at runtime to return a result set, a PROCEDURE %s can''t\nreturn a result set in the given context error occurs\n(ER_SP_BADSELECT).\n\nFor additional information about statements that are not allowed in\nstored routines, see\nhttp://dev.mysql.com/doc/refman/5.1/en/stored-program-restrictions.html\n.\n\nThe following example shows a simple stored procedure that uses an OUT\nparameter:\n\nmysql> delimiter //\n\nmysql> CREATE PROCEDURE simpleproc (OUT param1 INT)\n    -> BEGIN\n    ->   SELECT COUNT(*) INTO param1 FROM t;\n    -> END;\n    -> //\nQuery OK, 0 rows affected (0.00 sec)\n\nmysql> delimiter ;\n\nmysql> CALL simpleproc(@a);\nQuery OK, 0 rows affected (0.00 sec)\n\nmysql> SELECT @a;\n+------+\n| @a   |\n+------+\n| 3    |\n+------+\n1 row in set (0.00 sec)\n\nThe example uses the mysql client delimiter command to change the\nstatement delimiter from ; to // while the procedure is being defined.\nThis allows the ; delimiter used in the procedure body to be passed\nthrough to the server rather than being interpreted by mysql itself.\nSee\nhttp://dev.mysql.com/doc/refman/5.1/en/stored-programs-defining.html.\n\nFor information about invoking stored procedures from within programs\nwritten in a language that has a MySQL interface, see [HELP CALL].\n\nThe following example function takes a parameter, performs an operation\nusing an SQL function, and returns the result. In this case, it is\nunnecessary to use delimiter because the function definition contains\nno internal ; statement delimiters:\n\nmysql> CREATE FUNCTION hello (s CHAR(20))\nmysql> RETURNS CHAR(50) DETERMINISTIC\n    -> RETURN CONCAT(''Hello, '',s,''!'');\nQuery OK, 0 rows affected (0.00 sec)\n\nmysql> SELECT hello(''world'');\n+----------------+\n| hello(''world'') |\n+----------------+\n| Hello, world!  |\n+----------------+\n1 row in set (0.00 sec)\n\nMySQL stores the sql_mode system variable setting that is in effect at\nthe time a routine is created, and always executes the routine with\nthis setting in force, regardless of the server SQL mode in effect when\nthe routine is invoked.\n\nURL: http://dev.mysql.com/doc/refman/5.1/en/create-procedure.html\n\n', '', 'http://dev.mysql.com/doc/refman/5.1/en/create-procedure.html'),

Logically, this is\nequivalent to a DELETE statement that deletes all rows, but there are\npractical differences under some circumstances.\n\nFor an InnoDB table, InnoDB processes TRUNCATE TABLE by deleting rows\none by one if there are any FOREIGN KEY constraints that reference the\ntable. If there are no FOREIGN KEY constraints, InnoDB performs fast\ntruncation by dropping the original table and creating an empty one\nwith the same definition, which is much faster than deleting rows one\nby one. The AUTO_INCREMENT counter is reset by TRUNCATE TABLE,\nregardless of whether there is a FOREIGN KEY constraint.\n\nIn the case that FOREIGN KEY constraints reference the table, InnoDB\ndeletes rows one by one and processes the constraints on each one. If\nthe FOREIGN KEY constraint specifies DELETE CASCADE, rows from the\nchild (referenced) table are deleted, and the truncated table becomes\nempty. If the FOREIGN KEY constraint does not specify CASCADE, the\nTRUNCATE statement deletes rows one by one and stops if it encounters a\nparent row that is referenced by the child, returning this error:\n\nERROR 1451 (23000): Cannot delete or update a parent row: a foreign\nkey constraint fails (`test`.`child`, CONSTRAINT `child_ibfk_1`\nFOREIGN KEY (`parent_id`) REFERENCES `parent` (`id`))\n\nThis is the same as a DELETE statement with no WHERE clause.\n\nBeginning with MySQL 5.1.32, TRUNCATE is treated for purposes of binary\nlogging and replication as DROP TABLE followed by CREATE TABLE --- that\nis, as DDL rather than DML. This is due to the fact that, when using\nInnoDB and other transactional storage engines where the transaction\nisolation level does not allow for statement-based logging (READ\nCOMMITTED or READ UNCOMMITTED), the statement was not logged and\nreplicated when using STATEMENT or MIXED logging mode. (Bug#36763\n(http://bugs.mysql.com/36763)) However, it is still applied on\nreplication slaves using InnoDB in the manner described previously.\n\nThe count of rows affected by TRUNCATE TABLE is accurate only when it\nis mapped to a DELETE statement.\n\nFor other storage engines, TRUNCATE TABLE differs from DELETE in the\nfollowing ways in MySQL 5.1:\n\no Truncate operations drop and re-create the table, which is much\n  faster than deleting rows one by one, particularly for large tables.\n\no Truncate operations are not transaction-safe; an error occurs when\n  attempting one in the course of an active transaction or active table\n  lock.\n\no Truncation operations do not return the number of deleted rows.\n\no As long as the table format file tbl_name.frm is valid, the table can\n  be re-created as an empty table with TRUNCATE TABLE, even if the data\n  or index files have become corrupted.\n\no The table handler does not remember the last used AUTO_INCREMENT\n  value, but starts counting from the beginning. This is true even for\n  MyISAM and InnoDB, which normally do not reuse sequence values.\n\no When used with partitioned tables, TRUNCATE TABLE preserves the\n  partitioning; that is, the data and index files are dropped and\n  re-created, while the partition definitions (.par) file is\n  unaffected.\n\no Since truncation of a table does not make any use of DELETE, the\n  TRUNCATE statement does not invoke ON DELETE triggers.\n\nTRUNCATE TABLE requires the DROP privilege as of MySQL 5.1.16.

As of MySQL 5.1.12, the BDB storage engine is not supported,\nand this statement produces a warning.\n\nSHOW ENGINE INNODB STATUS displays extensive information about the\nstate of the InnoDB storage engine.\n\nThe InnoDB Monitors provide additional information about InnoDB\nprocessing. See\nhttp://dev.mysql.com/doc/refman/5.1/en/innodb-monitor.html.\n\nSHOW ENGINE INNODB MUTEX displays InnoDB mutex statistics. From MySQL\n5.1.2 to 5.1.14, the statement displays the following output fields:\n\no Type\n\n  Always InnoDB.\n\no Name\n\n  The mutex name and the source file where it is implemented. Example:\n  &pool->mutex:mem0pool.c\n\n  The mutex name indicates its purpose. For example, the log_sys mutex\n  is used by the InnoDB logging subsystem and indicates how intensive\n  logging activity is. The buf_pool mutex protects the InnoDB buffer\n  pool.\n\no Status\n\n  The mutex status. The fields contains several values:\n\n  o count indicates how many times the mutex was requested.\n\n  o spin_waits indicates how many times the spinlock had to run.\n\n  o spin_rounds indicates the number of spinlock rounds. (spin_rounds\n    divided by spin_waits provides the average round count.)\n\n  o os_waits indicates the number of operating system waits. This\n    occurs when the spinlock did not work (the mutex was not locked\n    during the spinlock and it was necessary to yield to the operating\n    system and wait).\n\n  o os_yields indicates the number of times a the thread trying to lock\n    a mutex gave up its timeslice and yielded to the operating system\n    (on the presumption that allowing other threads to run will free\n    the mutex so that it can be locked).\n\n  o os_wait_times indicates the amount of time (in ms) spent in\n    operating system waits, if the timed_mutexes system variable is 1\n    (ON). If timed_mutexes is 0 (OFF), timing is disabled, so\n    os_wait_times is 0. timed_mutexes is off by default.\n\nFrom MySQL 5.1.15 on, the statement displays the following output\nfields:\n\no Type\n\n  Always InnoDB.\n\no Name\n\n  The source file where the mutex is implemented, and the line number\n  in the file where the mutex is created. The line number may change\n  depending on your version of MySQL.\n\no Status\n\n  This field displays the same values as previously described (count,\n  spin_waits, spin_rounds, os_waits, os_yields, os_wait_times), but\n  only if UNIV_DEBUG was defined at MySQL compilation time (for\n  example, in include/univ.h in the InnoDB part of the MySQL source\n  tree). If UNIV_DEBUG was not defined, the statement displays only the\n  os_waits value. In the latter case (without UNIV_DEBUG), the\n  information on which the output is based is insufficient to\n  distinguish regular mutexes and mutexes that protect rw-locks (which\n  allow multiple readers or a single writer). Consequently, the output\n  may appear to contain multiple rows for the same mutex.\n\nInformation from this statement can be used to diagnose system\nproblems. For example, large values of spin_waits and spin_rounds may\nindicate scalability problems.\n\nIf the server has the NDBCLUSTER storage engine enabled, SHOW ENGINE\nNDB STATUS displays cluster status information such as the number of\nconnected data nodes, the cluster connectstring, and cluster binlog\nepochs, as well as counts of various Cluster API objects created by the\nMySQL Server when connected to the cluster.

The file name must be given as a literal string.\n\nLOAD DATA INFILE is the complement of SELECT ... INTO OUTFILE. (See\nhttp://dev.mysql.com/doc/refman/5.1/en/select.html.) To write data from\na table to a file, use SELECT ... INTO OUTFILE. To read the file back\ninto a table, use LOAD DATA INFILE. The syntax of the FIELDS and LINES\nclauses is the same for both statements. Both clauses are optional, but\nFIELDS must precede LINES if both are specified.\n\nFor more information about the efficiency of INSERT versus LOAD DATA\nINFILE and speeding up LOAD DATA INFILE, see\nhttp://dev.mysql.com/doc/refman/5.1/en/insert-speed.html.\n\nThe character set indicated by the character_set_database system\nvariable is used to interpret the information in the file. SET NAMES\nand the setting of character_set_client do not affect interpretation of\ninput. If the contents of the input file use a character set that\ndiffers from the default, it is usually preferable to specify the\ncharacter set of the file by using the CHARACTER SET clause, which is\navailable as of MySQL 5.1.17.\n\nLOAD DATA INFILE interprets all fields in the file as having the same\ncharacter set, regardless of the data types of the columns into which\nfield values are loaded. For proper interpretation of file contents,\nyou must ensure that it was written with the correct character set. For\nexample, if you write a data file with mysqldump -T or by issuing a\nSELECT ... INTO OUTFILE statement in mysql, be sure to use a\n--default-character-set option with mysqldump or mysql so that output\nis written in the character set to be used when the file is loaded with\nLOAD DATA INFILE.\n\nNote that it is currently not possible to load data files that use the\nucs2 character set.\n\nAs of MySQL 5.1.6, the character_set_filesystem system variable\ncontrols the interpretation of the file name.\n\nYou can also load data files by using the mysqlimport utility; it\noperates by sending a LOAD DATA INFILE statement to the server. The\n--local option causes mysqlimport to read data files from the client\nhost. You can specify the --compress option to get better performance\nover slow networks if the client and server support the compressed\nprotocol. See http://dev.mysql.com/doc/refman/5.1/en/mysqlimport.html.\n\nIf you use LOW_PRIORITY, execution of the LOAD DATA statement is\ndelayed until no other clients are reading from the table. This affects\nonly storage engines that use only table-level locking (MyISAM, MEMORY,\nMERGE).\n\nIf you specify CONCURRENT with a MyISAM table that satisfies the\ncondition for concurrent inserts (that is, it contains no free blocks\nin the middle), other threads can retrieve data from the table while\nLOAD DATA is executing. Using this option affects the performance of\nLOAD DATA a bit, even if no other thread is using the table at the same\ntime.\n\nCONCURRENT is not replicated when using statement-based replication;\nhowever, it is replicated when using row-based replication. See\nhttp://dev.mysql.com/doc/refman/5.1/en/replication-features-load-data.h\ntml, for more information.\n\n*Note*: Prior to MySQL 5.1.23, LOAD DATA performed very poorly when\nimporting into partitioned tables. The statement now uses buffering to\nimprove performance; however, the buffer uses 130 KB memory per\npartition to achieve this. (Bug#26527 (http://bugs.mysql.com/26527))\n\nThe LOCAL keyword, if specified, is interpreted with respect to the\nclient end of the connection:\n\no If LOCAL is specified, the file is read by the client program on the\n  client host and sent to the server. The file can be given as a full\n  path name to specify its exact location. If given as a relative path\n  name, the name is interpreted relative to the directory in which the\n  client program was started.\n\no If LOCAL is not specified, the file must be located on the server\n  host and is read directly by the server. The server uses the\n  following rules to locate the file:\n\n  o If the file name is an absolute path name, the server uses it as\n    given.\n\n  o If the file name is a relative path name with one or more leading\n    components, the server searches for the file relative to the\n    server''s data directory.\n\n  o If a file name with no leading components is given, the server\n    looks for the file in the database directory of the default\n    database.\n\nNote that, in the non-LOCAL case, these rules mean that a file named as\n./myfile.txt is read from the server''s data directory, whereas the file\nnamed as myfile.txt is read from the database directory of the default\ndatabase. For example, if db1 is the default database, the following\nLOAD DATA statement reads the file data.txt from the database directory\nfor db1, even though the statement explicitly loads the file into a\ntable in the db2 database:\n\nLOAD DATA INFILE ''data.txt'' INTO TABLE db2.my_table;\n\nWindows path names are specified using forward slashes rather than\nbackslashes. If you do use backslashes, you must double them.\n\nFor security reasons, when reading text files located on the server,\nthe files must either reside in the database directory or be readable\nby all. Also, to use LOAD DATA INFILE on server files, you must have\nthe FILE privilege. See\nhttp://dev.mysql.com/doc/refman/5.1/en/privileges-provided.html.

Also, record locks for non-matching rows are\nreleased after MySQL has evaluated the WHERE condition. As of MySQL\n5.1, if you use READ COMMITTED or enable\ninnodb_locks_unsafe_for_binlog, you must use row-based binary logging.\n\nThe following list describes how MySQL supports the different\ntransaction levels:\n\no READ UNCOMMITTED\n\n  SELECT statements are performed in a non-locking fashion, but a\n  possible earlier version of a row might be used. Thus, using this\n  isolation level, such reads are not consistent. This is also called a\n  "dirty read." Otherwise, this isolation level works like READ\n  COMMITTED.\n\no READ COMMITTED\n\n  A somewhat Oracle-like isolation level with respect to consistent\n  (non-locking) reads: Each consistent read, even within the same\n  transaction, sets and reads its own fresh snapshot. See\n  http://dev.mysql.com/doc/refman/5.1/en/innodb-consistent-read.html.\n\n  For locking reads (SELECT with FOR UPDATE or LOCK IN SHARE MODE),\n  InnoDB locks only index records, not the gaps before them, and thus\n  allows the free insertion of new records next to locked records. For\n  UPDATE and DELETE statements, locking depends on whether the\n  statement uses a unique index with a unique search condition (such as\n  WHERE id = 100), or a range-type search condition (such as WHERE id >\n  100). For a unique index with a unique search condition, InnoDB locks\n  only the index record found, not the gap before it. For range-type\n  searches, InnoDB locks the index range scanned, using gap locks or\n  next-key (gap plus index-record) locks to block insertions by other\n  sessions into the gaps covered by the range. This is necessary\n  because "phantom rows" must be blocked for MySQL replication and\n  recovery to work.\n\no REPEATABLE READ\n\n  This is the default isolation level for InnoDB. For consistent reads,\n  there is an important difference from the READ COMMITTED isolation\n  level: All consistent reads within the same transaction read the\n  snapshot established by the first read. This convention means that if\n  you issue several plain (non-locking) SELECT statements within the\n  same transaction, these SELECT statements are consistent also with\n  respect to each other. See\n  http://dev.mysql.com/doc/refman/5.1/en/innodb-consistent-read.html.\n\n  For locking reads (SELECT with FOR UPDATE or LOCK IN SHARE MODE),\n  UPDATE, and DELETE statements, locking depends on whether the\n  statement uses a unique index with a unique search condition, or a\n  range-type search condition. For a unique index with a unique search\n  condition, InnoDB locks only the index record found, not the gap\n  before it. For other search conditions, InnoDB locks the index range\n  scanned, using gap locks or next-key (gap plus index-record) locks to\n  block insertions by other sessions into the gaps covered by the\n  range.\n\no SERIALIZABLE\n\n  This level is like REPEATABLE READ, but InnoDB implicitly converts\n  all plain SELECT statements to SELECT ... LOCK IN SHARE MODE if\n  autocommit is disabled. If autocommit is enabled, the SELECT is its\n  own transaction. It therefore is known to be read only and can be\n  serialized if performed as a consistent (non-locking) read and need\n  not block for other transactions.

If the view does not exist,\nCREATE OR REPLACE VIEW is the same as CREATE VIEW. If the view does\nexist, CREATE OR REPLACE VIEW is the same as ALTER VIEW.\n\nThe select_statement is a SELECT statement that provides the definition\nof the view. (When you select from the view, you select in effect using\nthe SELECT statement.) select_statement can select from base tables or\nother views.\n\nThe view definition is "frozen" at creation time, so changes to the\nunderlying tables afterward do not affect the view definition. For\nexample, if a view is defined as SELECT * on a table, new columns added\nto the table later do not become part of the view.\n\nThe ALGORITHM clause affects how MySQL processes the view. The DEFINER\nand SQL SECURITY clauses specify the security context to be used when\nchecking access privileges at view invocation time. The WITH CHECK\nOPTION clause can be given to constrain inserts or updates to rows in\ntables referenced by the view. These clauses are described later in\nthis section.\n\nThe CREATE VIEW statement requires the CREATE VIEW privilege for the\nview, and some privilege for each column selected by the SELECT\nstatement. For columns used elsewhere in the SELECT statement you must\nhave the SELECT privilege. If the OR REPLACE clause is present, you\nmust also have the DROP privilege for the view.\n\nA view belongs to a database. By default, a new view is created in the\ndefault database. To create the view explicitly in a given database,\nspecify the name as db_name.view_name when you create it.\n\nmysql> CREATE VIEW test.v AS SELECT * FROM t;\n\nBase tables and views share the same namespace within a database, so a\ndatabase cannot contain a base table and a view that have the same\nname.\n\nViews must have unique column names with no duplicates, just like base\ntables. By default, the names of the columns retrieved by the SELECT\nstatement are used for the view column names. To define explicit names\nfor the view columns, the optional column_list clause can be given as a\nlist of comma-separated identifiers. The number of names in column_list\nmust be the same as the number of columns retrieved by the SELECT\nstatement.\n\n*Note*: Prior to MySQL 5.1.29, When you modify an existing view, the\ncurrent view definition is backed up and saved. It is stored in that\ntable''s database directory, in a subdirectory named arc. The backup\nfile for a view v is named v.frm-00001. If you alter the view again,\nthe next backup is named v.frm-00002. The three latest view backup\ndefinitions are stored. Backed up view definitions are not preserved by\nmysqldump, or any other such programs, but you can retain them using a\nfile copy operation. However, they are not needed for anything but to\nprovide you with a backup of your previous view definition. It is safe\nto remove these backup definitions, but only while mysqld is not\nrunning. If you delete the arc subdirectory or its files while mysqld\nis running, you will receive an error the next time you try to alter\nthe view: mysql> ALTER VIEW v AS SELECT * FROM t; ERROR 6 (HY000):\nError on delete of ''.\\test\\arc/v.frm-0004'' (Errcode: 2)\n\nColumns retrieved by the SELECT statement can be simple references to\ntable columns. They can also be expressions that use functions,\nconstant values, operators, and so forth.\n\nUnqualified table or view names in the SELECT statement are interpreted\nwith respect to the default database. A view can refer to tables or\nviews in other databases by qualifying the table or view name with the\nproper database name.\n\nA view can be created from many kinds of SELECT statements. It can\nrefer to base tables or other views. It can use joins, UNION, and\nsubqueries. The SELECT need not even refer to any tables. The following\nexample defines a view that selects two columns from another table, as\nwell as an expression calculated from those columns:\n\nmysql> CREATE TABLE t (qty INT, price INT);\nmysql> INSERT INTO t VALUES(3, 50);\nmysql> CREATE VIEW v AS SELECT qty, price, qty*price AS value FROM t;\nmysql> SELECT * FROM v;\n+------+-------+-------+\n| qty  | price | value |\n+------+-------+-------+\n|    3 |    50 |   150 |\n+------+-------+-------+\n\nA view definition is subject to the following restrictions:\n\no The SELECT statement cannot contain a subquery in the FROM clause.\n\no The SELECT statement cannot refer to system or user variables.\n\no Within a stored program, the definition cannot refer to program\n  parameters or local variables.\n\no The SELECT statement cannot refer to prepared statement parameters.\n\no Any table or view referred to in the definition must exist. However,\n  after a view has been created, it is possible to drop a table or view\n  that the definition refers to. In this case, use of the view results\n  in an error. To check a view definition for problems of this kind,\n  use the CHECK TABLE statement.\n\no The definition cannot refer to a TEMPORARY table, and you cannot\n  create a TEMPORARY view.\n\no Any tables named in the view definition must exist at definition\n  time.\n\no You cannot associate a trigger with a view.\n\nORDER BY is allowed in a view definition, but it is ignored if you\nselect from a view using a statement that has its own ORDER BY.\n\nFor other options or clauses in the definition, they are added to the\noptions or clauses of the statement that references the view, but the\neffect is undefined. For example, if a view definition includes a LIMIT\nclause, and you select from the view using a statement that has its own\nLIMIT clause, it is undefined which limit applies. This same principle\napplies to options such as ALL, DISTINCT, or SQL_SMALL_RESULT that\nfollow the SELECT keyword, and to clauses such as INTO, FOR UPDATE,\nLOCK IN SHARE MODE, and PROCEDURE.\n\nIf you create a view and then change the query processing environment\nby changing system variables, that may affect the results that you get\nfrom the view:\n\nmysql> CREATE VIEW v (mycol) AS SELECT ''abc'';\nQuery OK, 0 rows affected (0.01 sec)\n\nmysql> SET sql_mode = '''';\nQuery OK, 0 rows affected (0.00 sec)\n\nmysql> SELECT "mycol" FROM v;\n+-------+\n| mycol |\n+-------+\n| mycol | \n+-------+\n1 row in set (0.01 sec)\n\nmysql> SET sql_mode = ''ANSI_QUOTES'';\nQuery OK, 0 rows affected (0.00 sec)\n\nmysql> SELECT "mycol" FROM v;\n+-------+\n| mycol |\n+-------+\n| abc   | \n+-------+\n1 row in set (0.00 sec)\n\nThe DEFINER and SQL SECURITY clauses determine which MySQL account to\nuse when checking access privileges for the view when a statement is\nexecuted that references the view. They were addded in MySQL 5.1.2. The\nlegal SQL SECURITY characteristic values are DEFINER and INVOKER. These\nindicate that the required privileges must be held by the user who\ndefined or invoked the view, respectively. The default SQL SECURITY\nvalue is DEFINER.\n\nIf a user value is given for the DEFINER clause, it should be a MySQL\naccount in ''user_name''@''host_name'' format (the same format used in the\nGRANT statement). The user_name and host_name values both are required.\nThe definer can also be given as CURRENT_USER or CURRENT_USER(). The\ndefault DEFINER value is the user who executes the CREATE VIEW\nstatement. This is the same as specifying DEFINER = CURRENT_USER\nexplicitly.\n\nIf you specify the DEFINER clause, these rules determine the legal\nDEFINER user values:\n\no If you do not have the SUPER privilege, the only legal user value is\n  your own account, either specified literally or by using\n  CURRENT_USER. You cannot set the definer to some other account.\n\no If you have the SUPER privilege, you can specify any syntactically\n  legal account name. If the account does not actually exist, a warning\n  is generated.\n\no If the SQL SECURITY value is DEFINER but the definer account does not\n  exist when the view is referenced, an error occurs.\n\nWithin a view definition, CURRENT_USER returns the view''s DEFINER value\nby default as of MySQL 5.1.12. For older versions, and for views\ndefined with the SQL SECURITY INVOKER characteristic, CURRENT_USER\nreturns the account for the view''s invoker. For information about user\nauditing within views, see\nhttp://dev.mysql.com/doc/refman/5.1/en/account-activity-auditing.html.\n\nWithin a stored routine that is defined with the SQL SECURITY DEFINER\ncharacteristic, CURRENT_USER returns the routine''s DEFINER value. This\nalso affects a view defined within such a program, if the view\ndefinition contains a DEFINER value of CURRENT_USER.\n\nAs of MySQL 5.1.2 (when the DEFINER and SQL SECURITY clauses were\nimplemented), view privileges are checked like this:\n\no At view definition time, the view creator must have the privileges\n  needed to use the top-level objects accessed by the view. For\n  example, if the view definition refers to table columns, the creator\n  must have privileges for the columns, as described previously. If the\n  definition refers to a stored function, only the privileges needed to\n  invoke the function can be checked. The privileges required when the\n  function runs can be checked only as it executes: For different\n  invocations of the function, different execution paths within the\n  function might be taken.\n\no When a view is referenced, privileges for objects accessed by the\n  view are checked against the privileges held by the view creator or\n  invoker, depending on whether the SQL SECURITY characteristic is\n  DEFINER or INVOKER, respectively.\n\no If reference to a view causes execution of a stored function,\n  privilege checking for statements executed within the function depend\n  on whether the function is defined with a SQL SECURITY characteristic\n  of DEFINER or INVOKER. If the security characteristic is DEFINER, the\n  function runs with the privileges of its creator. If the\n  characteristic is INVOKER, the function runs with the privileges\n  determined by the view''s SQL SECURITY characteristic.\n\nPrior to MySQL 5.1.2 (before the DEFINER and SQL SECURITY clauses were\nimplemented), privileges required for objects used in a view are\nchecked at view creation time.\n\nExample: A view might depend on a stored function, and that function\nmight invoke other stored routines. For example, the following view\ninvokes a stored function f():\n\nCREATE VIEW v AS SELECT * FROM t WHERE t.id = f(t.name);\n\nSuppose that f() contains a statement such as this:\n\nIF name IS NULL then\n  CALL p1();\nELSE\n  CALL p2();\nEND IF;\n\nThe privileges required for executing statements within f() need to be\nchecked when f() executes. This might mean that privileges are needed\nfor p1() or p2(), depending on the execution path within f(). Those\nprivileges must be checked at runtime, and the user who must possess\nthe privileges is determined by the SQL SECURITY values of the view v\nand the function f().\n\nThe DEFINER and SQL SECURITY clauses for views are extensions to\nstandard SQL. In standard SQL, views are handled using the rules for\nSQL SECURITY INVOKER.\n\nIf you invoke a view that was created before MySQL 5.1.2, it is treated\nas though it was created with a SQL SECURITY DEFINER clause and with a\nDEFINER value that is the same as your account. However, because the\nactual definer is unknown, MySQL issues a warning. To make the warning\ngo away, it is sufficient to re-create the view so that the view\ndefinition includes a DEFINER clause.\n\nThe optional ALGORITHM clause is a MySQL extension to standard SQL. It\naffects how MySQL processes the view. ALGORITHM takes three values:\nMERGE, TEMPTABLE, or UNDEFINED. The default algorithm is UNDEFINED if\nno ALGORITHM clause is present. For more information, see\nhttp://dev.mysql.com/doc/refman/5.1/en/view-algorithms.html.\n\nSome views are updatable. That is, you can use them in statements such\nas UPDATE, DELETE, or INSERT to update the contents of the underlying\ntable. For a view to be updatable, there must be a one-to-one\nrelationship between the rows in the view and the rows in the\nunderlying table. There are also certain other constructs that make a\nview non-updatable.\n\nThe WITH CHECK OPTION clause can be given for an updatable view to\nprevent inserts or updates to rows except those for which the WHERE\nclause in the select_statement is true.\n\nIn a WITH CHECK OPTION clause for an updatable view, the LOCAL and\nCASCADED keywords determine the scope of check testing when the view is\ndefined in terms of another view. The LOCAL keyword restricts the CHECK\nOPTION only to the view being defined. CASCADED causes the checks for\nunderlying views to be evaluated as well. When neither keyword is\ngiven, the default is CASCADED.\n\nFor more information about updatable views and the WITH CHECK OPTION\nclause, see\nhttp://dev.mysql.com/doc/refman/5.1/en/view-updatability.html.\n\nURL: http://dev.mysql.com/doc/refman/5.1/en/create-view.html\n\n', '', 'http://dev.mysql.com/doc/refman/5.1/en/create-view.html'),

This is a common situation\nwhen you use MySQL for logging and you also periodically run SELECT and\nUPDATE statements that take a long time to complete.\n\nWhen a client uses INSERT DELAYED, it gets an okay from the server at\nonce, and the row is queued to be inserted when the table is not in use\nby any other thread.\n\nAnother major benefit of using INSERT DELAYED is that inserts from many\nclients are bundled together and written in one block. This is much\nfaster than performing many separate inserts.\n\nNote that INSERT DELAYED is slower than a normal INSERT if the table is\nnot otherwise in use. There is also the additional overhead for the\nserver to handle a separate thread for each table for which there are\ndelayed rows. This means that you should use INSERT DELAYED only when\nyou are really sure that you need it.\n\nThe queued rows are held only in memory until they are inserted into\nthe table. This means that if you terminate mysqld forcibly (for\nexample, with kill -9) or if mysqld dies unexpectedly, any queued rows\nthat have not been written to disk are lost.\n\nThere are some constraints on the use of DELAYED:\n\no INSERT DELAYED works only with MyISAM, MEMORY, ARCHIVE, and (as of\n  MySQL 5.1.19) BLACKHOLE tables.

ON DUPLICATE KEY UPDATE statements.\n\no Because the INSERT DELAYED statement returns immediately, before the\n  rows are inserted, you cannot use LAST_INSERT_ID() to get the\n  AUTO_INCREMENT value that the statement might generate.\n\no DELAYED rows are not visible to SELECT statements until they actually\n  have been inserted.\n\no DELAYED is ignored on slave replication servers, so that INSERT\n  DELAYED is treated as a normal INSERT on slaves. This is because\n  DELAYED could cause the slave to have different data than the master.\n\no Pending INSERT DELAYED statements are lost if a table is write locked\n  and ALTER TABLE is used to modify the table structure.\n\no INSERT DELAYED is not supported for views.\n\no INSERT DELAYED is not supported for partitioned tables.\n\nURL: http://dev.mysql.com/doc/refman/5.1/en/insert-delayed.html\n\n', '', 'http://dev.mysql.com/doc/refman/5.1/en/insert-delayed.html'),
