儲存過程排錯，一般要用錯誤處理器。詳細內容參考上方連結。

使用示例：

##定義一個錯誤資訊展示函式，方便儲存過程展示更精確的錯誤資訊

DELIMITER $$

CREATE FUNCTION fn_get_error()

RETURNS VARCHAR(250)

BEGIN

    DECLARE code CHAR(5) DEFAULT '00000';

    DECLARE msg TEXT;

    DECLARE errno INT;

    GET DIAGNOSTICS CONDITION 1 code = RETURNED_SQLSTATE,  

        errno = MYSQL_ERRNO, msg = MESSAGE_TEXT;

    RETURN COALESCE(CONCAT("ERROR ", errno, " (", code, "): ", msg), '-');

END

$$  

##定義相關的儲存過程，可參照此模板寫儲存過程，對排錯和維護有意義

DELIMITER $$

CREATE PROCEDURE procedure_name()

BEGIN

    DECLARE errpos int default 0;

    DECLARE EXIT HANDLER FOR SQLEXCEPTION SELECT 'SQLException encountered' as No_TLucky, errpos as Position_Error,fn_get_error() AS  Error_massage;

set errpos=1;/*錯誤位置1*/

    insert into test.test set  name='p1';

set errpos=2;

    insert into test.test set  name='p2';

set errpos=3;

    insert into test.test set  name='p3';

insert into test.test set  name=p2;

END
