Before starting to debug a MySQL stored procedure, you need to deploy a Debug Engine to the server. Studio for MySQL will create a cr_debug database and fill it with stored routines and tables. To deploy a Debug
create procedure pr_add ( a int, b int ) as - 错误,MySQL 不需要 “as” begin mysql statement ...; end; 5. 如果 MySQL 存储过程中包含多条 MySQL 语句,则需要 begin end 关键字。 create procedure pr_add ( a int, b int ) begin mysql statement 1 ...; mysql statement 2 ...; end;...
SQL语句需要先编译然后执行,而存储过程(Stored Procedure)是一组为了完成特定功能的SQL语句集, 经编译后存储在数据库中,用户通过指定存储过程的名字并给定参数(如果该存储过程带有参数)来调用执行它。 ``` ## 二、存储过程的特点 ### 优点 ``` 1、能完成较复杂的判断和运算 2、可编程行强,灵活 3、SQL编程的...

MySQL Workbench是一个图形化的数据库设计和管理工具,它提供了对存储过程的调试支持。 设置断点:在MySQL Workbench中打开存储过程编辑器,在需要设置断点的行上点击行号左侧的灰色边框。 启动调试:右键点击存储过程名称,选择"Debug Stored Procedure"来启动调试。 单步执行:使用调试工具栏上的按钮(如"Step Over"、"Step...
存储过程debug可通过在关键位置添加PRINT语句输出变量值,或使用数据库提供的调试工具,如MySQL的DELIMITER和DEBUG命令。 存储过程(Stored Procedure)是一组为了完成特定功能的SQL语句集合,它被存储在数据库中并通过名字来调用,调试存储过程可能比调试普通的SQL语句更为复杂,因为它涉及到程序流程控制、异常处理以及多条SQL语句...
1、检查用户权限:需要确认当前用户是否具有足够的权限来操作存储过程,可以通过查询数据库系统的权限表或使用相关命令来查看用户的权限,在MySQL中,可以使用以下命令查看用户权限: SHOW GRANTS FOR 'username'@'host'; 2、检查存储过程所有者:确保存储过程的所有者具有相应的权限,如果存储过程是由其他用户创建的,那么当前...
