创建程序以列出特定数据库中附带详细信息的表格。
假设当前我们正在使用一个名为“query”的数据库,它包含以下表格 -
mysql> Show tables in query; +-----------------+ | Tables_in_query | +-----------------+ | student_detail | | student_info | +-----------------+ 2 rows in set (0.00 sec)
以下是将为我们提供包含详细信息的表格列表的存储过程 -
mysql> DELIMITER// mysql> CREATE procedure tablelist() -> BEGIN -> Select * from Information_schema.tables WHERE table_schema = 'query'; -> END // Query OK, 0 rows affected (0.06 sec) mysql> DELIMITER; mysql> CALL tablelist()\G *************************** 1. row *************************** TABLE_CATALOG: def TABLE_SCHEMA: query TABLE_NAME: student_detail TABLE_TYPE: BASE TABLE ENGINE: InnoDB VERSION: 10 ROW_FORMAT: Dynamic TABLE_ROWS: 4 AVG_ROW_LENGTH: 4096 DATA_LENGTH: 16384 MAX_DATA_LENGTH: 0 INDEX_LENGTH: 0 DATA_FREE: 0 AUTO_INCREMENT: NULL CREATE_TIME: 2017-12-13 16:25:44 UPDATE_TIME: NULL CHECK_TIME: NULL TABLE_COLLATION: latin1_swedish_ci CHECKSUM: NULL CREATE_OPTIONS: TABLE_COMMENT: *************************** 2. row *************************** TABLE_CATALOG: def TABLE_SCHEMA: query TABLE_NAME: student_info TABLE_TYPE: BASE TABLE ENGINE: InnoDB VERSION: 10 ROW_FORMAT: Dynamic TABLE_ROWS: 4 AVG_ROW_LENGTH: 4096 DATA_LENGTH: 16384 MAX_DATA_LENGTH: 0 INDEX_LENGTH: 0 DATA_FREE: 0 AUTO_INCREMENT: NULL CREATE_TIME: 2017-12-12 09:52:51 UPDATE_TIME: NULL CHECK_TIME: NULL TABLE_COLLATION: latin1_swedish_ci CHECKSUM: NULL CREATE_OPTIONS: TABLE_COMMENT: 2 rows in set (0.01 sec) Query OK, 0 rows affected (0.06 sec)
