Question

当我在没有存储过程的情况下进行查询时，我对存储过程不熟悉它工作正常，但是当我运行存储过程时它显示错误。

ERROR 1690（22003）：BIGINT UNSIGNED值超出范围

DELIMITER ;;

DROP PROCEDURE IF EXISTS sp_price;
Create Procedure sp_price(
 IN user_date INT,
 OUT exp INT,

BEGIN

select case 
          when (cast((((start_date) + (31536000 * a))-t2.start_time) as unsigned) )>0  
             then sum(t2.price) 
          else 0 
       end 
into exp 
from product t1 
join customer t2 on t1.p_id=t2.c_id 
where t2.created >= user_date; 

END

Answer 1

也许您需要将变量exp声明为unsigned

示例：

 ....
   Create Procedure sp_price(
   IN user_date INT,
   OUT exp INT unsigned
 ....

Answer 2

终于工作了!!!这是解决了一个......

select case 
          when (((start_date) + (31536000 * a))- (cast(t2.start_time) as signed))>0  
             then sum(t2.price) 
          else 0 
       end 
into exp 
from product t1 
join customer t2 on t1.p_id=t2.c_id 
where t2.created >= user_date;

如何在存储过程中使用CAST作为SIGNED来解决BIGINT - MYSQL？
