SHOW提供了许多关于数据库、表、列或服务器状态信息的表单。本节将介绍以下内容：

SHOW {  BINARY | MASTER} LOGSSHOW BINLOG EVENTS [IN 'log_name'] [FROM pos] [LIMIT [offset,] row_count]SHOW CHARACTER SET [like_or_where]SHOW COLLATION [like_or_where]SHOW [FULL] COLUMNS FROM tbl_name [FROM db_name] [like_or_where]SHOW CREATE DATABASE db_nameSHOW CREATE EVENT event_nameSHOW CREATE FUNCTION func_nameSHOW CREATE PROCEDURE proc_nameSHOW CREATE TABLE tbl_nameSHOW CREATE TRIGGER trigger_nameSHOW CREATE VIEW view_nameSHOW DATABASES [like_or_where]SHOW ENGINE engine_name {  STATUS | MUTEX}SHOW [STORAGE] ENGINESSHOW ERRORS [LIMIT [offset,] row_count]SHOW EVENTSSHOW FUNCTION CODE func_nameSHOW FUNCTION STATUS [like_or_where]SHOW GRANTS FOR userSHOW INDEX FROM tbl_name [FROM db_name]SHOW MASTER STATUSSHOW OPEN TABLES [FROM db_name] [like_or_where]SHOW PLUGINSSHOW PROCEDURE CODE proc_nameSHOW PROCEDURE STATUS [like_or_where]SHOW PRIVILEGESSHOW [FULL] PROCESSLISTSHOW PROFILE [types] [FOR QUERY n] [OFFSET n] [LIMIT n]SHOW PROFILESSHOW RELAYLOG EVENTS [IN 'log_name'] [FROM pos] [LIMIT [offset,] row_count]SHOW {REPLICAS | SLAVE HOSTS}SHOW {REPLICA | SLAVE} STATUS [FOR CHANNEL channel]SHOW [GLOBAL | SESSION] STATUS [like_or_where]SHOW TABLE STATUS [FROM db_name] [like_or_where]SHOW [FULL] TABLES [FROM db_name] [like_or_where]SHOW TRIGGERS [FROM db_name] [like_or_where]SHOW [GLOBAL | SESSION] VARIABLES [like_or_where]SHOW WARNINGS [LIMIT [offset,] row_count]like_or_where: {    LIKE 'pattern'  | WHERE expr}

如果给定的SHOW语句包含LIKE 'pattern'部分，'pattern'是一个可以包含%和_ SQL 通配符的字符串。该模式用于将语句输出为限制匹配的值。

一些SHOW语句还接受WHERE子句，该子句在指定显示哪些行方面提供了更大的灵活性。参见。

许多 MySQL API（比如 PHP）允许你处理SHOW语句返回的结果，就像处理SELECT语句返回的结果一样；有关更多信息，请参阅或您的 API 文档。此外，您可以对INFORMATION_SCHEMA数据库中的表的查询结果进行 SQL 处理，而使用SHOW语句的结果则不容易做到这一点。参见。
