Otherwise, REVOKE executes normally; if the user does\n  not exist, the statement raises an error.\n\n  Example: Given table t1 in database test, we execute the following\n  statements, with the results shown.\n\nmysql> CREATE USER jerry@localhost;\nQuery OK, 0 rows affected (0.01 sec)\n\nmysql> REVOKE SELECT ON test.t1 FROM jerry@localhost;\nERROR 1147 (42000): There is no such grant defined for user \'jerry\' on host\n\'localhost\' on table \'t1\' \nmysql> REVOKE IF EXISTS SELECT ON test.t1 FROM jerry@localhost;\nQuery OK, 0 rows affected, 1 warning (0.00 sec)\n\nmysql> SHOW WARNINGS\\G\n*************************** 1. row ***************************\n  Level: Warning\n   Code: 1147\nMessage: There is no such grant defined for user \'jerry\' on host \'localhost\' on\ntable \'t1\' \n1 row in set (0.00 sec)\n\n  IF EXISTS causes an error to be demoted to a warning even if the\n  privilege or role named does not exist, or the statement attempts to\n  assign it at the wrong level.\n\no If the REVOKE statement includes IGNORE UNKNOWN USER, the statement\n  raises a warning for any target user or role named in the statement\n  but not found; if no target named by the statement exists, REVOKE\n  succeeds but has no actual effect. Otherwise, the statement executes\n  as usual, and attempting to revoke a privilege not assigned to the\n  target for whatever reason raises an error, as expected.\n\n  Example (continuing from the previous example):\n\nmysql> DROP USER IF EXISTS jerry@localhost;\nQuery OK, 0 rows affected (0.01 sec)\n\nmysql> REVOKE SELECT ON test.t1 FROM jerry@localhost;\nERROR 1147 (42000): There is no such grant defined for user \'jerry\' on host\n\'localhost\' on table \'t1\' \nmysql> REVOKE SELECT ON test.t1 FROM jerry@localhost IGNORE UNKNOWN USER;\nQuery OK, 0 rows affected, 1 warning (0.01 sec)\n\nmysql> SHOW WARNINGS\\G\n*************************** 1. row ***************************\n  Level: Warning\n   Code: 3162\nMessage: Authorization ID jerry does not exist.\n1 row in set (0.00 sec)\n\no The combination of IF EXISTS and IGNORE UNKNOWN USER means that\n  REVOKE never raises an error for an unknown target user or role or\n  for an unassigned or unavailable privilege, and the statement as\n  whole in such cases succeeds; roles or privileges are removed from\n  existing target users or roles whenever possible, and any revocation\n  which is not possible raises a warning and executes as a NOOP.\n\n  Example (again continuing from example in the previous item):\n\n# No such user, no such role\nmysql> DROP ROLE IF EXISTS Bogus;\nQuery OK, 0 rows affected, 1 warning (0.02 sec)\n\nmysql> SHOW WARNINGS;\n+-------+------+----------------------------------------------+\n| Level | Code | Message                                      |\n+-------+------+----------------------------------------------+\n| Note  | 3162 | Authorization ID \'Bogus\'@\'%\' does not exist. |\n+-------+------+----------------------------------------------+\n1 row in set (0.00 sec)\n\n# This statement attempts to revoke a nonexistent role from a nonexistent user\nmysql> REVOKE Bogus ON test FROM jerry@localhost;\nERROR 3619 (HY000): Illegal privilege level specified for test\n\n# The same, with IF EXISTS\nmysql> REVOKE IF EXISTS Bogus ON test FROM jerry@localhost;\nERROR 1147 (42000): There is no such grant defined for user \'jerry\' on host\n\'localhost\' on table \'test\' \n\n# The same, with IGNORE UNKNOWN USER\nmysql> REVOKE Bogus ON test FROM jerry@localhost IGNORE UNKNOWN USER;\nERROR 3619 (HY000): Illegal privilege level specified for test\n\n# The same, with both options\nmysql> REVOKE IF EXISTS Bogus ON test FROM jerry@localhost IGNORE UNKNOWN USER;\nQuery OK, 0 rows affected, 2 warnings (0.01 sec)\n\nmysql> SHOW WARNINGS;\n+---------+------+--------------------------------------------+\n| Level   | Code | Message                                    |\n+---------+------+--------------------------------------------+\n| Warning | 3619 | Illegal privilege level specified for test |\n| Warning | 3162 | Authorization ID jerry does not exist.     |\n+---------+------+--------------------------------------------+\n2 rows in set (0.00 sec)\n\nRoles named in the mandatory_roles system variable value cannot be\nrevoked. When IF EXISTS and IGNORE UNKNOWN USER are used together in a\nstatement that tries to remove a mandatory privilege, the error\nnormally raised by attempting to do this is demoted to a warning; the\nstatement executes successfully, but does not make any changes.\n\nA revoked role immediately affects any user account from which it was\nrevoked, such that within any current session for the account, its\nprivileges are adjusted for the next statement executed.\n\nRevoking a role revokes the role itself, not the privileges that it\nrepresents. Suppose that an account is granted a role that includes a\ngiven privilege, and is also granted the privilege explicitly or\nanother role that includes the privilege. In this case, the account\nstill possesses that privilege if the first role is revoked. For\nexample, if an account is granted two roles that each include SELECT,\nthe account still can select after either role is revoked.\n\nREVOKE ALL ON *.* (at the global level) revokes all granted static\nglobal privileges and all granted dynamic privileges.\n\nA revoked privilege that is granted but not known to the server is\nrevoked with a warning. This situation can occur for dynamic\nprivileges. For example, a dynamic privilege can be granted while the\ncomponent that registers it is installed, but if that component is\nsubsequently uninstalled, the privilege becomes unregistered, although\naccounts that possess the privilege still possess it and it can be\nrevoked from them.\n\nURL: https://dev.mysql.com/doc/refman/8.0/en/revoke.html\n\n','','https://dev.mysql.com/doc/refman/8.0/en/revoke.html'),(618,'SET DEFAULT ROLE',46,'Syntax:\nSET DEFAULT ROLE\n    {NONE | ALL | role [, role ] ...}\n    TO user [, user ] ...\n\nFor each user named immediately after the TO keyword, this statement\ndefines which roles become active when the user connects to the server\nand authenticates, or when the user executes the SET ROLE DEFAULT\nstatement during a session.\n\nSET DEFAULT ROLE is alternative syntax for ALTER USER ...

(In particular, you can\n  change your own password.) To see which account the server\n  authenticated you as, invoke the CURRENT_USER() function:\n\nSELECT CURRENT_USER();\n\nIf a FOR user clause is given, the account name uses the format\ndescribed in\nhttps://dev.mysql.com/doc/refman/8.0/en/account-names.html.

(The plugin is given the opportunity to hash the value\ninto the encryption format it expects. The plugin may use the value as\nspecified, in which case no hashing occurs.)\n\nSetting the password for a named account (with a FOR clause) requires\nthe UPDATE privilege for the mysql system schema.

(CREATE\nFUNCTION is also used to created stored functions; see [HELP CREATE\nPROCEDURE].)\n\nA loadable function is a way to extend MySQL with a new function that\nworks like a native (built-in) MySQL function such as ABS() or\nCONCAT(). See Adding a Loadable Function\n(https://dev.mysql.com/doc/extending-mysql/8.0/en/adding-loadable-funct\nion.html).\n\nfunction_name is the name that should be used in SQL statements to\ninvoke the function. The RETURNS clause indicates the type of the\nfunction\'s return value. DECIMAL is a legal value after RETURNS, but\ncurrently DECIMAL functions return string values and should be written\nlike STRING functions.\n\nIF NOT EXISTS prevents an error from occurring if there already exists\na loadable function with the same name. It does not prevent an error\nfrom occurring if there already exists a built-in function having the\nsame name. IF NOT EXISTS is supported for CREATE FUNCTION statements\nbeginning with MySQL 8.0.29. See also\nhttps://dev.mysql.com/doc/refman/8.0/en/function-resolution.html#functi\non-name-resolution.\n\nThe AGGREGATE keyword, if given, signifies that the function is an\naggregate (group) function. An aggregate function works exactly like a\nnative MySQL aggregate function such as SUM() or COUNT().\n\nshared_library_name is the base name of the shared library file\ncontaining the code that implements the function. The file must be\nlocated in the plugin directory. This directory is given by the value\nof the plugin_dir system variable. For more information, see\nhttps://dev.mysql.com/doc/refman/8.0/en/function-loading.html.\n\nCREATE FUNCTION requires the INSERT privilege for the mysql system\nschema because it adds a row to the mysql.func system table to register\nthe function.\n\nCREATE FUNCTION also adds the function to the Performance Schema\nuser_defined_functions table that provides runtime information about\ninstalled loadable functions. See\nhttps://dev.mysql.com/doc/refman/8.0/en/performance-schema-user-defined\n-functions-table.html.\n\n*Note*:\n\nLike the mysql.func system table, the Performance Schema\nuser_defined_functions table lists loadable functions installed using\nCREATE FUNCTION. Unlike the mysql.func table, the\nuser_defined_functions table also lists loadable functions installed\nautomatically by server components or plugins. This difference makes\nuser_defined_functions preferable to mysql.func for checking which\nloadable functions are installed.\n\nDuring the normal startup sequence, the server loads functions\nregistered in the mysql.func table. If the server is started with the\n--skip-grant-tables option, functions registered in the table are not\nloaded and are unavailable.\n\nURL: https://dev.mysql.com/doc/refman/8.0/en/create-function-loadable.html\n\n','','https://dev.mysql.com/doc/refman/8.0/en/create-function-loadable.html'),(631,'DROP FUNCTION LOADABLE FUNCTION',48,'Syntax:\nDROP FUNCTION [IF EXISTS] function_name\n\nThis statement drops the loadable function named function_name.

(These naming details are subject to change\nbecause component name interpretation is itself performed by a service\nand the component infrastructure makes it possible to replace the\ndefault service implementation with alternative implementations.)\n\nIf any error occurs, the statement fails and has no effect. For\nexample, this happens if a component name is erroneous, a named\ncomponent does not exist or is already installed, or component\ninitialization fails.\n\nA loader service handles component loading, which includes adding\ninstalled components to the mysql.component system table that serves as\na registry.

Plugin names are not case-sensitive. For maximal\ncompatibility, plugin names should be limited to ASCII letters, digits,\nand underscore because they are used in C source files, shell command\nlines, M4 and Bourne shell scripts, and SQL environments.\n\nshared_library_name is the name of the shared library that contains the\nplugin code. 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 chance 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\nsystem table. During the normal startup sequence, the server loads and\ninitializes plugins registered in mysql.plugin. This means that a\nplugin is installed with INSTALL PLUGIN only once, not every time the\nserver starts. If the server is started with the --skip-grant-tables\noption, plugins registered in the mysql.plugin table are not loaded and\nare unavailable.\n\nA plugin library can contain multiple plugins. For each of them to be\ninstalled, use a separate INSTALL PLUGIN statement.

That is, a CHECK constraint originally specified as part\nof a column definition displays as a separate clause not part of the\ncolumn definition. Example:\n\nmysql> CREATE TABLE t1 (\n         i1 INT CHECK (i1 <> 0),      -- column constraint\n         i2 INT,\n         CHECK (i2 > i1),             -- table constraint\n         CHECK (i2 <> 0) NOT ENFORCED -- table constraint, not enforced\n       );\n\nmysql> SHOW CREATE TABLE t1\\G\n*************************** 1. row ***************************\n       Table: t1\nCreate Table: CREATE TABLE `t1` (\n  `i1` int DEFAULT NULL,\n  `i2` int DEFAULT NULL,\n  CONSTRAINT `t1_chk_1` CHECK ((`i1` <> 0)),\n  CONSTRAINT `t1_chk_2` CHECK ((`i2` > `i1`)),\n  CONSTRAINT `t1_chk_3` CHECK ((`i2` <> 0)) /*!80016 NOT ENFORCED */\n) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_0900_ai_ci\n\nSHOW CREATE TABLE quotes table and column names according to the value\nof the sql_quote_show_create option. See\nhttps://dev.mysql.com/doc/refman/8.0/en/server-system-variables.html.\n\nWhen altering the storage engine of a table, table options that are not\napplicable to the new storage engine are retained in the table\ndefinition to enable reverting the table with its previously defined\noptions to the original storage engine, if necessary. For example, when\nchanging the storage engine from InnoDB to MyISAM, options specific to\nInnoDB, such as ROW_FORMAT=COMPACT, are retained, as shown here:\n\nmysql> CREATE TABLE t1 (c1 INT PRIMARY KEY) ROW_FORMAT=COMPACT ENGINE=InnoDB;\nmysql> ALTER TABLE t1 ENGINE=MyISAM;\nmysql> SHOW CREATE TABLE t1\\G\n*************************** 1. row ***************************\n       Table: t1\nCreate Table: CREATE TABLE `t1` (\n  `c1` int NOT NULL,\n  PRIMARY KEY (`c1`)\n) ENGINE=MyISAM DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_0900_ai_ci ROW_FORMAT=COMPACT\n\nWhen creating a table with strict mode disabled, the storage engine\'s\ndefault row format is used if the specified row format is not\nsupported. The actual row format of the table is reported in the\nRow_format column in response to SHOW TABLE STATUS. SHOW CREATE TABLE\nshows the row format that was specified in the CREATE TABLE statement.\n\nIn MySQL 8.0.30 and later, SHOW CREATE TABLE includes the definition of\nthe table\'s generated invisible primary key, if it has such a key, by\ndefault.

Statistics for low-level operating system mutexes, which are\n  implemented outside of InnoDB, are not reported.\n\n  o spins indicates the number of spins.\n\n  o waits indicates the number of mutex waits.\n\n  o calls indicates how many times the mutex was requested.\n\nSHOW ENGINE INNODB MUTEX does not list mutexes and rw-locks for each\nbuffer pool block, as the amount of output would be overwhelming on\nsystems with a large buffer pool. SHOW ENGINE INNODB MUTEX does,\nhowever, print aggregate BUF_BLOCK_MUTEX spin, wait, and call values\nfor buffer pool block mutexes and rw-locks. SHOW ENGINE INNODB MUTEX\nalso does not list any mutexes or rw-locks that have never been waited\non (os_waits=0). Thus, SHOW ENGINE INNODB MUTEX only displays\ninformation about mutexes and rw-locks outside of the buffer pool that\nhave caused at least one OS-level wait.\n\nUse SHOW ENGINE PERFORMANCE_SCHEMA STATUS to inspect the internal\noperation of the Performance Schema code:\n\nmysql> SHOW ENGINE PERFORMANCE_SCHEMA STATUS\\G\n...\n*************************** 3. row ***************************\n  Type: performance_schema\n  Name: events_waits_history.size\nStatus: 76\n*************************** 4. row ***************************\n  Type: performance_schema\n  Name: events_waits_history.count\nStatus: 10000\n*************************** 5. row ***************************\n  Type: performance_schema\n  Name: events_waits_history.memory\nStatus: 760000\n...\n*************************** 57. row ***************************\n  Type: performance_schema\n  Name: performance_schema.memory\nStatus: 26459600\n...\n\nThis statement is intended to help the DBA understand the effects that\ndifferent Performance Schema options have on memory requirements.\n\nName values consist of two parts, which name an internal buffer and a\nbuffer attribute, respectively. Interpret buffer names as follows:\n\no An internal buffer that is not exposed as a table is named within\n  parentheses. Examples: (pfs_cond_class).size,\n  (pfs_mutex_class).memory.\n\no An internal buffer that is exposed as a table in the\n  performance_schema database is named after the table, without\n  parentheses. Examples: events_waits_history.size,\n  mutex_instances.count.\n\no A value that applies to the Performance Schema as a whole begins with\n  performance_schema. Example: performance_schema.memory.\n\nBuffer attributes have these meanings:\n\no size is the size of the internal record used by the implementation,\n  such as the size of a row in a table. size values cannot be changed.\n\no count is the number of internal records, such as the number of rows\n  in a table. count values can be changed using Performance Schema\n  configuration options.\n\no For a table, tbl_name.memory is the product of size and count. For\n  the Performance Schema as a whole, performance_schema.memory is the\n  sum of all the memory used (the sum of all other memory values).\n\nIn some cases, there is a direct relationship between a Performance\nSchema configuration parameter and a SHOW ENGINE value. For example,\nevents_waits_history_long.count corresponds to\nperformance_schema_events_waits_history_long_size. In other cases, the\nrelationship is more complex. For example, events_waits_history.count\ncorresponds to performance_schema_events_waits_history_size (the number\nof rows per thread) multiplied by\nperformance_schema_max_thread_instances ( the number of threads).\n\nSHOW ENGINE NDB STATUS If the server has the NDB storage engine\nenabled, SHOW ENGINE NDB STATUS displays cluster status information\nsuch as the number of connected data nodes, the cluster connectstring,\nand cluster binary log epochs, as well as counts of various Cluster API\nobjects created by the MySQL Server when connected to the cluster.\nSample output from this statement is shown here:\n\nmysql> SHOW ENGINE NDB STATUS;\n+------------+-----------------------+--------------------------------------------------+\n| Type       | Name                  | Status                                           |\n+------------+-----------------------+--------------------------------------------------+\n| ndbcluster | connection            | cluster_node_id=7,\n  connected_host=198.51.100.103, connected_port=1186, number_of_data_nodes=4,\n  number_of_ready_data_nodes=3, connect_count=0                                         |\n| ndbcluster | NdbTransaction        | created=6, free=0, sizeof=212                    |\n| ndbcluster | NdbOperation          | created=8, free=8, sizeof=660                    |\n| ndbcluster | NdbIndexScanOperation | created=1, free=1, sizeof=744                    |\n| ndbcluster | NdbIndexOperation     | created=0, free=0, sizeof=664                    |\n| ndbcluster | NdbRecAttr            | created=1285, free=1285, sizeof=60               |\n| ndbcluster | NdbApiSignal          | created=16, free=16, sizeof=136                  |\n| ndbcluster | NdbLabel              | created=0, free=0, sizeof=196                    |\n| ndbcluster | NdbBranch             | created=0, free=0, sizeof=24                     |\n| ndbcluster | NdbSubroutine         | created=0, free=0, sizeof=68                     |\n| ndbcluster | NdbCall               | created=0, free=0, sizeof=16                     |\n| ndbcluster | NdbBlob               | created=1, free=1, sizeof=264                    |\n| ndbcluster | NdbReceiver           | created=4, free=0, sizeof=68                     |\n| ndbcluster | binlog                | latest_epoch=155467, latest_trans_epoch=148126,\n  latest_received_binlog_epoch=0, latest_handled_binlog_epoch=0,\n  latest_applied_binlog_epoch=0                                                         |\n+------------+-----------------------+--------------------------------------------------+\n\nThe Status column in each of these rows provides information about the\nMySQL server\'s connection to the cluster and about the cluster binary\nlog\'s status, respectively.

This can have values A\n  (ascending), D (descending), or NULL (not sorted).\n\no Cardinality\n\n  An estimate of the number of unique values in the index. To update\n  this number, run ANALYZE TABLE or (for MyISAM tables) myisamchk -a.\n\n  Cardinality is counted based on statistics stored as integers, so the\n  value is not necessarily exact even for small tables. The higher the\n  cardinality, the greater the chance that MySQL uses the index when\n  doing joins.\n\no Sub_part\n\n  The index prefix.

However, prefix lengths for\n  index specifications in CREATE TABLE, ALTER TABLE, and CREATE INDEX\n  statements are interpreted as number of characters for nonbinary\n  string types (CHAR, VARCHAR, TEXT) and number of bytes for binary\n  string types (BINARY, VARBINARY, BLOB). Take this into account when\n  specifying a prefix length for a nonbinary string column that uses a\n  multibyte character set.\n\n  For additional information about index prefixes, see\n  https://dev.mysql.com/doc/refman/8.0/en/column-indexes.html, and\n  [HELP CREATE INDEX].\n\no Packed\n\n  Indicates how the key is packed.

For details,\nsee\nhttps://dev.mysql.com/doc/refman/8.0/en/performance-schema-replication-\ntables.html.\n\nFrom MySQL 8.0.27, you can set the GTID_ONLY option on the CHANGE\nREPLICATION SOURCE TO statement to stop a replication channel from\npersisting file names and file positions in the replication metadata\nrepositories. With this setting, file positions for the source binary\nlog file and the relay log file are tracked in memory. The SHOW REPLICA\nSTATUS statement still displays file positions in normal use. However,\nbecause the file positions are not being regularly updated in the\nconnection metadata repository and the applier metadata repository\nexcept in a few situations, they are likely to be out of date if the\nserver is restarted.\n\nFor a replication channel with the GTID_ONLY setting after a server\nstart, the read and applied file positions for the source binary log\nfile (Read_Source_Log_Pos and Exec_Source_Log_Pos) are set to zero, and\nthe file names (Source_Log_File and Relay_Source_Log_File) are set to\nINVALID. The relay log file name (Relay_Log_File) is set according to\nthe relay_log_recovery setting, either a new file that was created at\nserver start or the first relay log file present. The file position\n(Relay_Log_Pos) is set to position 4, and GTID auto-skip is used to\nskip any transactions in the file that were already applied.\n\nWhen the receiver thread contacts the source and gets valid position\ninformation, the read position (Read_Source_Log_Pos) and file name\n(Source_Log_File) are updated with the correct data and become valid.\nWhen the applier thread applies a transaction from the source, or skips\nan already executed transaction, the executed position\n(Exec_Source_Log_Pos) and file name (Relay_Source_Log_File) are updated\nwith the correct data and become valid. The relay log file position\n(Relay_Log_Pos) is also updated at that time.\n\nURL: https://dev.mysql.com/doc/refman/8.0/en/show-replica-status.html\n\n','','https://dev.mysql.com/doc/refman/8.0/en/show-replica-status.html'),(681,'SHOW SLAVE STATUS',3,'Syntax:\nSHOW {SLAVE | REPLICA} STATUS [FOR CHANNEL channel]\n\nThis statement provides status information on essential parameters of\nthe replica threads.

It requires the\nSHUTDOWN privilege.\n\nOne use for RESTART is when it is not possible or convenient to gain\ncommand-line access to the MySQL server on the server host to restart\nit. For example, SET PERSIST_ONLY can be used at runtime to make\nconfiguration changes to system variables that can be set only at\nserver startup, but the server must still be restarted for those\nchanges to take effect. The RESTART statement provides a way to do so\nfrom within client sessions, without requiring command-line access on\nthe server host.\n\n*Note*:\n\nAfter executing a RESTART statement, the client can expect the current\nconnection to be lost. If auto-reconnect is enabled, the connection is\nreestablished after the server restarts. Otherwise, the connection must\nbe reestablished manually.\n\nA successful RESTART operation requires mysqld to be running in an\nenvironment that has a monitoring process available to detect a server\nshutdown performed for restart purposes:\n\no In the presence of a monitoring process, RESTART causes mysqld to\n  terminate such that the monitoring process can determine that it\n  should start a new mysqld instance.\n\no If no monitoring process is present, RESTART fails with an error.\n\nThese platforms provide the necessary monitoring support for the\nRESTART statement:\n\no Windows, when mysqld is started as a Windows service or standalone.\n  (mysqld forks, and one process acts as a monitor to the other, which\n  acts as the server.)\n\no Unix and Unix-like systems that use systemd or mysqld_safe to manage\n  mysqld.\n\nTo configure a monitoring environment such that mysqld enables the\nRESTART statement:\n\n1. Set the MYSQLD_PARENT_PID environment variable to the value of the\n   process ID of the process that starts mysqld, before starting\n   mysqld.\n\n2. When mysqld performs a shutdown due to use of the RESTART statement,\n   it returns exit code 16.\n\n3. When the monitoring process detects an exit code of 16, it starts\n   mysqld again. Otherwise, it exits.\n\nHere is a minimal example as implemented in the bash shell:\n\n#!/bin/bash\n\nexport MYSQLD_PARENT_PID=$$\n\nexport MYSQLD_RESTART_EXIT=16\n\nwhile true ; do\n  bin/mysqld mysqld options here\n  if [ $? -ne $MYSQLD_RESTART_EXIT ]; then\n    break\n  fi\ndone\n\nOn Windows, the forking used to implement RESTART makes determining the\nserver process to attach to for debugging more difficult. To alleviate\nthis, starting the server with --gdb suppresses forking, in addition to\nits other actions done to set up a debugging environment. In non-debug\nsettings, --no-monitor may be used for the sole purpose of suppressing\nforking the monitor process. For a server started with either --gdb or\n--no-monitor, executing RESTART causes the server to simply exit\nwithout restarting.\n\nURL: https://dev.mysql.com/doc/refman/8.0/en/restart.html\n\n','','https://dev.mysql.com/doc/refman/8.0/en/restart.html'),(696,'SHUTDOWN',3,'Syntax:\nSHUTDOWN\n\nThis statement stops the MySQL server.
