显示 MySQL 存储过程的描述
mysqlmysqli database
要显示存储过程的描述，语法如下 −
SHOW CREATE PROCEDURE yourProcedureName();
首先我们创建一个存储过程 −
mysql> DELIMITER // mysql> CREATE PROCEDURE sample_Procedure() BEGIN SELECT "HELLO MYSQL!!!!"; END // Query OK, 0 rows affected (0.18 sec) mysql> DELIMITER ;
使用 CALL 命令调用存储过程。
mysql> call sample_Procedure();
这将产生以下输出 −
+-----------------+ | HELLO MYSQL!!!! | +-----------------+ | HELLO MYSQL!!!! | +-----------------+ 1 row in set (0.00 sec) Query OK, 0 rows affected (0.01 sec)
以下查询显示上面创建的 MySQL 存储过程的描述 −
mysql> show create procedure sample_Procedure;
这将产生以下输出 −
+------------------+--------------------------------------------+-----------------------------------------------------------------------------------------------+----------------------+----------------------+--------------------+ | Procedure | sql_mode | Create Procedure | character_set_client | collation_connection | Database Collation | +------------------+--------------------------------------------+-----------------------------------------------------------------------------------------------+----------------------+----------------------+--------------------+ | sample_Procedure | STRICT_TRANS_TABLES,NO_ENGINE_SUBSTITUTION | CREATE DEFINER=`root`@`%` PROCEDURE `sample_Procedure`() BEGIN SELECT "HELLO MYSQL!!!!"; END | utf8 | utf8_general_ci | utf8_unicode_ci | +------------------+--------------------------------------------+-----------------------------------------------------------------------------------------------+----------------------+----------------------+--------------------+ 1 row in set (0.00 sec)
