13.7.5.9 SHOW CREATE PROCEDURE 语句

SHOW CREATE PROCEDURE proc_name

此语句是 MySQL 扩展。它返回确切的字符串 ，可用于重新创建命名的存储过程。SHOW CREATE FUNCTION，显示有关存储函数的信息 （参见第 13.7.5.8 节“ SHOW CREATE FUNCTION 语句”）。

您必须是 routine 子句或具有对表的 SELECT 访问权限。

mysql> SHOW CREATE PROCEDURE test.citycount\G

character_set_client 是系统变量。 是 collation_connection系统 变量。 是数据库的排序规则
