A session can acquire or\nrelease locks only for itself.

It is subject to\nremoval 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 as\nof MySQL 4.1 and removed in MySQL 5.5.\n\nThe recommended alternative solution to using LOAD DATA FROM MASTER or\nLOAD TABLE FROM MASTER is using mysqldump or mysqlhotcopy. The latter\nrequires Perl and two Perl modules (DBI and DBD:mysql) and works for\nMyISAM and ARCHIVE tables only. With mysqldump, you can create SQL\ndumps on the master and pipe (or copy) these to a mysql client on the\nslave. This has the advantage of working for all storage engines, but\ncan be quite slow, since it works 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\nnonunique 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.

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.

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 Setting @@global.slave_net_timeout to a value less than that of the\n current heartbeat interval results in a warning being issued. The\n effect of issuing RESET SLAVE on the heartbeat interval is to reset\n it to the default value.\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\nSetting MASTER_HOST=\'\' --- that is, setting its value explicitly to an\nempty string --- is not the same as not setting it at all.

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.

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\nTo invoke a stored procedure, use the CALL statement (see [HELP CALL]).\nTo invoke a stored function, refer to it in an expression. The function\nreturns a value during expression evaluation.\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. This behavior can be changed by disabling the\nautomatic_sp_privileges system variable. See\nhttp://dev.mysql.com/doc/refman/5.1/en/stored-routines-privileges.html… 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\… 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,\na syntax error occurs unless you use a space between the name and the\nfollowing parenthesis when defining the routine or invoking it later.\nFor this reason, avoid 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 stored routine\nname, regardless 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 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 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//\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-defini… 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 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\nParameter types and function return types can be declared to use any\nvalid data type, except that the COLLATE attribute cannot be used.\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… 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 can be used within a stored\nprocedcure but not within a stored function. This prohibition includes\nSELECT statements that do not have an INTO var_list clause and other\nstatements such as SHOW, EXPLAIN, and CHECK TABLE. For statements that\ncan be determined at function definition time to return a result set, a\nNot allowed to return a result set from a function error occurs\n(ER_SP_NO_RETSET). For statements that can be determined only at\nruntime to return a result set, a PROCEDURE %s can\'t return a result\nset in the given context error occurs (ER_SP_BADSELECT).\n\nUSE statements within stored routines are disallowed. When a routine is\ninvoked, an implicit USE db_name is performed (and undone when the\nroutine terminates). The causes the routine to have the given default\ndatabase while it executes. References to objects in databases other\nthan the routine default database should be qualified with the\nappropriate database name.\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.htm… information about invoking stored procedures from within programs\nwritten in a language that has a MySQL interface, see [HELP CALL].\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\nThe switch from the SQL mode of the invoker to that of the routine\noccurs after evaluation of arguments and assignment of the resulting\nvalues to routine parameters.

(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 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).

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 from the\nstandard InnoDB Monitor about the state of the InnoDB storage engine.\nFor information about the standard monitor and other InnoDB Monitors\nthat provide information about InnoDB processing, see\nhttp://dev.mysql.com/doc/refman/5.1/en/innodb-monitors.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.

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.

As a workaround, you can specify the correct database with\nthe USE statement prior to executing LOAD DATA.

The name includes the file name extension (for example,\nlibmyplugin.so, libmyplugin.dll, or libmyplugin.dylib).\n\nThe shared library must be located in the plugin directory (the\ndirectory named by the plugin_dir system variable). The library must be\nin the plugin directory itself, not in a subdirectory. By default,\nplugin_dir is the plugin directory under the directory named by the\npkglibdir configuration variable, but it can be changed by setting the\nvalue of plugin_dir at server startup. For example, set its value in a\nmy.cnf file:\n\n[mysqld]\nplugin_dir=/path/to/plugin/directory\n\nIf the value of plugin_dir is a relative path name, it is taken to be\nrelative to the MySQL base directory (the value of the basedir system\nvariable).\n\nINSTALL PLUGIN loads and initializes the plugin code to make the plugin\navailable for use. A plugin is initialized by executing its\ninitialization function, which handles any setup that the plugin must\nperform before it can be used. When the server shuts down, it executes\nthe deinitialization function for each plugin that is loaded so that\nthe plugin has a change to perform any final cleanup.\n\nINSTALL PLUGIN also registers the plugin by adding a line that\nindicates the plugin name and library file name to the mysql.plugin\ntable.

The string contains the words to search for.\n It can also contain operators that specify requirements such that a\n word must be present or absent in matching rows, or that it should be\n weighted higher or lower than usual. Common words such as "some" or\n "then" are stopwords and do not match if present in the search\n string. The IN BOOLEAN MODE modifier specifies a boolean search. For\n more information, see\n http://dev.mysql.com/doc/refman/5.1/en/fulltext-boolean.html.\n\no A natural language search interprets the search string as a phrase in\n natural human language (a phrase in free text). There are no special\n operators. The stopword list applies. In addition, words that are\n present in 50% or more of the rows are considered common and do not\n match. Full-text searches are natural language searches if the IN\n NATURAL LANGUAGE MODE modifier is given or if no modifier is given.\n\no A query expansion search is a modification of a natural language\n search. The search string is used to perform a natural language\n search. Then words from the most relevant rows returned by the search\n are added to the search string and the search is done again. The\n query returns the rows from the second search. The IN NATURAL\n LANGUAGE MODE WITH QUERY EXPANSION or WITH QUERY EXPANSION modifier\n specifies a query expansion search.

For\ninformation about checking Event Scheduler status and enabling it if\nnecessary, see\nhttp://dev.mysql.com/doc/refman/5.1/en/events-configuration.html.\n\nT… minimum requirements for a valid CREATE EVENT statement are as\nfollows:\n\no The keywords CREATE EVENT plus an event name, which uniquely\n identifies the event within a database schema. (Prior to MySQL\n 5.1.12, the event name needed to be unique only among events created\n by the same user within a schema.)\n\no An ON SCHEDULE clause, which determines when and how often the event\n executes.\n\no A DO clause, which contains the SQL statement to be executed by an\n event.\n\nThis is an example of a minimal CREATE EVENT statement:\n\nCREATE EVENT myevent\n ON SCHEDULE AT CURRENT_TIMESTAMP + INTERVAL 1 HOUR\n DO\n UPDATE myschema.mytable SET mycol = mycol + 1;\n\nThe previous statement creates an event named myevent. This event\nexecutes once --- one hour following its creation --- by running an SQL\nstatement that increments the value of the myschema.mytable table\'s\nmycol column by 1.\n\nThe event_name must be a valid MySQL identifier with a maximum length\nof 64 characters. Event names are not case sensitive, so you cannot\nhave two events named myevent and MyEvent in the same schema. In\ngeneral, the rules governing event names are the same as those for\nnames of stored routines. See\nhttp://dev.mysql.com/doc/refman/5.1/en/identifiers.html.\n\nAn event is associated with a schema. If no schema is indicated as part\nof event_name, the default (current) schema is assumed. To create an\nevent in a specific schema, qualify the event name with a schema using\nschema_name.event_name syntax.\n\nURL: http://dev.mysql.com/doc/refman/5.1/en/create-event.html\n\n','','http://dev.mysql.com/doc/refman/5.1/en/create-event.html'); insert into help_topic (help_topic_id,help_category_id,name,description,example,url) values (88,4,'ABS','Syntax:\nABS(X)\n\nReturns the absolute value of X.\n\nURL: http://dev.mysql.com/doc/refman/5.1/en/mathematical-functions.html\n\n','mysql> SELECT ABS(2);\n -> 2\nmysql> SELECT ABS(-32);\n -> 32\n','http://dev.mysql.com/doc/refman/5.1/en/mathematical-functions.html'); insert into help_topic (help_topic_id,help_category_id,name,description,example,url) values (89,31,'POLYFROMWKB','PolyFromWKB(wkb[,srid]), PolygonFromWKB(wkb[,srid])\n\nConstructs a POLYGON value using its WKB representation and SRID.\n\nURL: http://dev.mysql.com/doc/refman/5.1/en/creating-spatial-values.html#gis-wkb…','','http://dev.mysql.com/doc/refman/5.1/en/creating-spatial-values.html#gis-wkb…'); insert into help_topic (help_topic_id,help_category_id,name,description,example,url) values (90,35,'NOT LIKE','Syntax:\nexpr NOT LIKE pat [ESCAPE \'escape_char\']\n\nThis is the same as NOT (expr LIKE pat [ESCAPE \'escape_char\']).\n\nURL: http://dev.mysql.com/doc/refman/5.1/en/string-comparison-functions.html\n\n','','http://dev.mysql.com/doc/refman/5.1/en/string-comparison-functions.html'); @@ -170,7 +170,7 @@ insert into help_topic (help_topic_id,he insert into help_topic (help_topic_id,help_category_id,name,description,example,url) values (101,11,'COMPRESS','Syntax:\nCOMPRESS(string_to_compress)\n\nCompresses a string and returns the result as a binary string.

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 Setting @@global.slave_net_timeout to a value less than that of the\n current heartbeat interval results in a warning being issued. The\n effect of issuing RESET SLAVE on the heartbeat interval is to reset\n it to the default value.\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\nSetting MASTER_HOST=\'\' --- that is, setting its value explicitly to an\nempty string --- is not the same as not setting it at all. Setting this\noption to an empty string causes START SLAVE subsequently to fail. This\nissue is addressed in MySQL 5.5. (Bug#28796\n(http://bugs.mysql.com/28796))\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'); +insert into help_topic (help_topic_id,help_category_id,name,description,example,url) values (184,25,'CHANGE MASTER TO','Syntax:\nCHANGE MASTER TO option [, option] ...\n\noption:\n MASTER_BIND = \'interface_name\'\n | MASTER_HOST = \'host_name\'\n | MASTER_USER = \'user_name\'\n | MASTER_PASSWORD = \'password\'\n | MASTER_PORT = port_num\n | MASTER_CONNECT_RETRY = interval\n | MASTER_HEARTBEAT_PERIOD = interval\n | MASTER_LOG_FILE = \'master_log_name\'\n | MASTER_LOG_POS = master_log_pos\n | RELAY_LOG_FILE = \'relay_log_name\'\n | RELAY_LOG_POS = relay_log_pos\n | MASTER_SSL = {0|1}\n | MASTER_SSL_CA = \'ca_file_name\'\n | MASTER_SSL_CAPATH = \'ca_directory_name\'\n | MASTER_SSL_CERT = \'cert_file_name\'\n | MASTER_SSL_KEY = \'key_file_name\'\n | MASTER_SSL_CIPHER = \'cipher_list\'\n | MASTER_SSL_VERIFY_SERVER_CERT = {0|1}\n\nCHANGE MASTER TO changes the parameters that the slave server uses for\nconnecting to the master server, for reading the master binary log, and\nreading the slave relay log.

For example, if the password to connect to\nyour MySQL master has changed, you just need to issue these statements\nto 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\nMASTER_HOST, MASTER_USER, MASTER_PASSWORD, and MASTER_PORT provide\ninformation to the slave about how to connect to its master:\n\no MASTER_HOST and MASTER_PORT are the host name (or IP address) of the\n master host and its TCP/IP port.\n\n *Note*: Replication cannot use Unix socket files.

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 next two options (MASTER_BIND and MASTER_HEARTBEAT_PERIOD) are\navailable in MySQL Cluster NDB 6.3 and later, but are not supported in\nmainline MySQL 5.1:\n\nMASTER_BIND is for use on replication slaves having multiple network\ninterfaces, and determines which of the slave\'s network interfaces is\nchosen for connecting to the master.

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.

See\nhttp://dev.mysql.com/doc/refman/5.1/en/stored-routines-privileges.html… 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\… 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,\na syntax error occurs unless you use a space between the name and the\nfollowing parenthesis when defining the routine or invoking it later.\nFor this reason, avoid 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 stored routine\nname, regardless 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 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 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//\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-defini… 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 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\nParameter types and function return types can be declared to use any\nvalid data type, except that the COLLATE attribute cannot be used.\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… 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 can be used within a stored\nprocedcure but not within a stored function. This prohibition includes\nSELECT statements that do not have an INTO var_list clause and other\nstatements such as SHOW, EXPLAIN, and CHECK TABLE. For statements that\ncan be determined at function definition time to return a result set, a\nNot allowed to return a result set from a function error occurs\n(ER_SP_NO_RETSET).

A plugin is initialized by executing its\ninitialization function, which handles any setup that the plugin must\nperform before it can be used.\n\nTo use INSTALL PLUGIN, you must have the INSERT privilege for the\nmysql.plugin table.\n\nAt server startup, the server loads and initializes any plugin that is\nlisted in the mysql.plugin table.

You may optionally follow this integer value\nwith a one-letter abbreviation for an order of magnitude, similar to\nthose used in my.cnf. Generally, this is one of the letters M (for\nmegabytes) or G (for gigabytes).\n\n*Note*: All MySQL Cluster Disk Data objects share the same namespace.\nThis means that each Disk Data object must be uniquely named (and not\nmerely each Disk Data object of a given type).

ADD DATAFILE statements.\n\nUsing DROP DATAFILE with ALTER TABLESPACE drops the data file\n\'file_name\' from the tablespace. This file must already have been added\nto the tablespace using CREATE TABLESPACE or ALTER TABLESPACE;\notherwise an error will result.\n\nBoth ALTER TABLESPACE ... ADD DATAFILE and ALTER TABLESPACE ... DROP\nDATAFILE require an ENGINE clause which specifies the storage engine\nused by the tablespace. In MySQL 5.1, the only accepted values for\nengine_name are NDB and NDBCLUSTER.\n\nWAIT is parsed but otherwise ignored, and so has no effect in MySQL\n5.1. It is intended for future expansion.\n\nWhen ALTER TABLESPACE ... ADD DATAFILE is used with ENGINE = NDB, a\ndata file is created on each Cluster data node. You can verify that the\ndata files were created and obtain information about them by querying\nthe INFORMATION_SCHEMA.FILES table.

In MySQL 5.1, it is useful\nonly with Disk Data storage for MySQL Cluster. See\nhttp://dev.mysql.com/doc/refman/5.1/en/mysql-cluster-disk-data.html.\n…: http://dev.mysql.com/doc/refman/5.1/en/alter-tablespace.html\n\n','','http://dev.mysql.com/doc/refman/5.1/en/alter-tablespace.html'); +insert into help_topic (help_topic_id,help_category_id,name,description,example,url) values (474,37,'ALTER TABLESPACE','Syntax:\nALTER TABLESPACE tablespace_name\n {ADD|DROP} DATAFILE \'file_name\'\n [INITIAL_SIZE [=] size]\n [WAIT]\n ENGINE [=] engine_name\n\nThis statement can be used either to add a new data file, or to drop a\ndata file from a tablespace.\n\nThe ADD DATAFILE variant allows you to specify an initial size using an\nINITIAL_SIZE clause, where size is measured in bytes; the default value\nis 128M (128 megabytes). You may optionally follow this integer value\nwith a one-letter abbreviation for an order of magnitude, similar to\nthose used in my.cnf. Generally, this is one of the letters M (for\nmegabytes) or G (for gigabytes).\n\n*Note*: All MySQL Cluster Disk Data objects share the same namespace.\nThis means that each Disk Data object must be uniquely named (and not\nmerely each Disk Data object of a given type). For example, you cannot\nhave a tablespace and an data file with the same name, or an undo log\nfile and a with the same name.\n\nPrior to MySQL Cluster NDB 6.2.17, 6.3.23, and 6.4.3, path and file\nnames for data files could not be longer than 128 characters.\n(Bug#31770 (http://bugs.mysql.com/bug.php?id=31770))\n\nOn 32-bit systems, the maximum supported value for INITIAL_SIZE is 4G.\n(Bug#29186 (http://bugs.mysql.com/bug.php?id=29186))\n\nINITIAL_SIZE is rounded as for CREATE TABLESPACE. Beginning with MySQL\nCluster NDB 6.2.19, MySQL Cluster NDB 6.3.32, MySQL Cluster NDB 7.0.13,\nand MySQL Cluster NDB 7.1.2, this rounding is done explicitly (also as\nwith CREATE TABLESPACE).\n\nOnce a data file has been created, its size cannot be changed; however,\nyou can add more data files to the tablespace using additional ALTER\nTABLESPACE ... ADD DATAFILE statements.\n\nUsing DROP DATAFILE with ALTER TABLESPACE drops the data file\n\'file_name\' from the tablespace. This file must already have been added\nto the tablespace using CREATE TABLESPACE or ALTER TABLESPACE;\notherwise an error will result.\n\nBoth ALTER TABLESPACE ... ADD DATAFILE and ALTER TABLESPACE ... DROP\nDATAFILE require an ENGINE clause which specifies the storage engine\nused by the tablespace. In MySQL 5.1, the only accepted values for\nengine_name are NDB and NDBCLUSTER.\n\nWAIT is parsed but otherwise ignored, and so has no effect in MySQL\n5.1. It is intended for future expansion.\n\nWhen ALTER TABLESPACE ... ADD DATAFILE is used with ENGINE = NDB, a\ndata file is created on each Cluster data node. You can verify that the\ndata files were created and obtain information about them by querying\nthe INFORMATION_SCHEMA.FILES table. For example, the following query\nshows all data files belonging to the tablespace named newts:\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| lg_3 | newdata2.dat | CLUSTER_NODE=3 |\n| lg_3 | newdata2.dat | CLUSTER_NODE=4 |\n+--------------------+--------------+----------------+\n2 rows in set (0.03 sec)\n\nSee http://dev.mysql.com/doc/refman/5.1/en/files-table.html.\n\nALTER TABLESPACE was added in MySQL 5.1.6.

[Maria-developers] Windows test platforms
by Bo Thorsen 26 Apr '10

26 Apr '10

Hi everyone, I'm going to build a set of Windows installations to run buildbot on. But finding the right set of versions to do this is a challenge. There are so many versions of Windows that it's impossible to get even close to the full set of them. So I'd like to have a good set of systems that pretty much cover most options. The buildbot system will work in three parts. One will build a set of installable packages - for now probably just a zip file. Another will install these packages and test them on clean systems. A third will do compilation tests on OS/Compiler combinations. Windows 2000 or earlier is not going to be done. I'm not sure about Windows Server 2003. I'd like to skip XP, as MS cut support for it, but I think there are too many live installations to do this yet. For building the installable packages, I intend to use XP and Visual Studio 2008. My list of systems to test the packages and do the compile + make test on would be: XP Pro 32 bit Vista 32 bit Windows 7 64 bit Server 2008 64 bit On XP, I'd install VC++ 2005, on the others VC++ 2008. When Visual Studio 2010 is out, I'll install that on Vista and one of the 64 bit systems. This is four systems that does a very thin span of the incredible amount of systems done by MS. (And people say there are a lot of Linux distributions.) Does this make sense to you? Please let me know what you think. Kind regards, Bo Thorsen, Monty Program AB.

The package build won't. Is this what you expected? Kind regards, Bo Thorsen, Monty Program AB.

The only reason I didn't choose VS2010 is that it's only beta at this moment. When it's out of beta, I agree we should use this instead. However, having a test buildbot system with the 2010 beta is probably a good idea, to get rid of compiler problems from it. > Bo> My list of systems to test the packages and do the compile + make test > on Bo> would be: > > Bo> XP Pro 32 bit > Bo> Vista 32 bit > Bo> Windows 7 64 bit > Bo> Server 2008 64 bit > > Bo> On XP, I'd install VC++ 2005, on the others VC++ 2008.

I hope we can have just two packages - 32 and 64 bit - that will install on all Windows systems. There might be differences between the systems that have to be handled in the packages, but I don't want to have two packages per Windows version. That would be *really* bad. Kind regards, Bo Thorsen, Monty Program AB.
