查看MySQL中的存储过程/函数定义?
要在MySQL中查看存储过程/函数定义,可以使用show命令。语法如下-
SHOW CREATE PROCEDURE yourProcedureName;
要了解上述语法,您可以创建一个过程并检查该定义。让我们创建一个存储过程-
mysql> delimiter //mysql> create procedure AllRecords() -> begin
-> select *from student;
-> end //
您可以在call命令的帮助下调用存储过程。查询如下-
mysql> delimiter ;mysql> call AllRecords();
以下是输出-
+------+-------+| id | Name |
+------+-------+
| 1 | John |
| 2 | Bob |
| 3 | Smith |
| 6 | John |
+------+-------+
4 rows in set (0.14 sec)
现在,您可以在开始讨论的上述语法的帮助下检查定义。查询如下-
mysql> show create procedure AllRecords;
这是输出-
+------------+--------------------------------------------+-----------------------------------------------------------------------+----------------------+----------------------+--------------------+| Procedure | sql_mode | Create Procedure | character_set_client | collation_connection | Database Collation |
+------------+--------------------------------------------+-----------------------------------------------------------------------+----------------------+----------------------+--------------------+
| AllRecords | STRICT_TRANS_TABLES,NO_ENGINE_SUBSTITUTION | CREATE DEFINER=`root`@`%` PROCEDURE `AllRecords`() begin select *from student;end | utf8 | utf8_general_ci | utf8mb4_unicode_ci |
+------------+--------------------------------------------+-----------------------------------------------------------------------+----------------------+----------------------+--------------------+
1 row in set (0.00 sec)
要检查MySQL中的函数定义,可以使用函数代替过程。语法如下:-
SHOW CREATE FUNCTION yourFunctionName;
