我们常用的操作数据库语言SQL语句在执行的时候需要要先编译,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。 一个存储过程是一个可编程的函数,它在数据库中创建并保存。它可以有SQL语句...
例如: DELIMITER//CREATEPROCEDUREDebugExample()BEGINDECLAREcountUsersINT;SELECTCOUNT(*)INTOcountUsersFROMusers;IFcountUsers=0THENSELECT'No users found.';-- 反馈信息ELSESELECTCONCAT(countUsers,' users found.');-- 反馈信息ENDIF;END//DELIMITER; 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. ...

The first approach is the same as use of debugging package DBMS_DEBUG in Oracle; it is used in dbForge Studio for MySQL. This approach guarantees validity of executed code, as an executed stored procedure/function/trigger does the same operations and gives the same result as during usual exec...
DELIMITER // CREATE PROCEDURE `example_procedure`(IN param1 INT) BEGIN DECLARE result INT; SET result = param1 * 2; SELECT CONCAT('Result: ', result) AS debug_info; END // DELIMITER ; 参考链接 MySQL官方文档 - 存储过程 MySQL官方文档 - 函数 通过以上信息,您可以更好地理解和调试MySQL中的...
在MySQL/MariaDB中,存储过程(stored procedure)、存储函数(stored function)、触发器(trigger)、事件(event)统称为存储程序(stored programs)。此外,存储过程和存储函数还合称为stored routines。 对于函数来说,除了存储函数,还有用户自定义函数(UDF,user defined function),在MySQL/MariaDB中,用户自定义函数是存储函数...

Doing it this way it would also be easy to turn debugging on and off, so either globally or locally to your procedure you can set a value which tells the mysql_debug procedure to write to the table or not. When I'm developing Oracle stored procedures I use script files and then ...
