SHOW has many forms that provide information about databases, tables, columns, or status information about the server. This section describes those following:

SHOW [FULL] COLUMNS FROM tbl_name [FROM db_name] [LIKE 'pattern']
SHOW CREATE DATABASE db_name
SHOW CREATE TABLE tbl_name
SHOW DATABASES [LIKE 'pattern']
SHOW ENGINE engine_name {LOGS | STATUS }
SHOW [STORAGE] ENGINES
SHOW ERRORS [LIMIT [offset,] row_count]
SHOW GRANTS FOR user
SHOW INDEX FROM tbl_name [FROM db_name]
SHOW INNODB STATUS
SHOW [BDB] LOGS
SHOW PRIVILEGES
SHOW [FULL] PROCESSLIST
SHOW [GLOBAL | SESSION] STATUS [LIKE 'pattern']
SHOW TABLE STATUS [FROM db_name] [LIKE 'pattern']
SHOW [OPEN] TABLES [FROM db_name] [LIKE 'pattern']
SHOW [GLOBAL | SESSION] VARIABLES [LIKE 'pattern']
SHOW WARNINGS [LIMIT [offset,] row_count]

The SHOW statement also has forms that provide information about replication master and slave servers and are described in Section 13.6, “Replication Statements”:

SHOW BINARY LOGS
SHOW BINLOG EVENTS
SHOW MASTER STATUS
SHOW SLAVE HOSTS
SHOW SLAVE STATUS

If the syntax for a given SHOW statement includes a LIKE 'pattern' part, 'pattern' is a string that can contain the SQL ‘%’ and ‘_’ wildcard characters. The pattern is useful for restricting statement output to matching values.

Many MySQL APIs (such as PHP) allow you to treat the result returned from a SHOW statement as you would a result set from a SELECT; see Chapter 17, APIs and Libraries, or your API documentation for more information.
