MYSQL-查看数据库中的存储过程语法（六）

article 2024/10/19 21:10:15

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
*************************** 1. row ***************************
           Procedure: citycount
            sql_mode: ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,
                      NO_ZERO_IN_DATE,NO_ZERO_DATE,
                      ERROR_FOR_DIVISION_BY_ZERO,
                      NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION
    Create Procedure: CREATE DEFINER=`me`@`localhost`
                      PROCEDURE `citycount`(IN country CHAR(3), OUT cities INT)
                      BEGIN
                        SELECT COUNT(*) INTO cities FROM world.city
                        WHERE CountryCode = country;
                      END

mysql> SHOW CREATE FUNCTION test.hello\G

                      RETURNS char(50) CHARSET latin1
