我有一个抛出错误的存储过程。
这是电话：
CALL campaign_strat_placement_test（'10541'，'2013-1-1'，'2013-1-7'，2,0， 2 ，0,0,32）
我已经粗体化导致错误的部分，因为如果我将该选项更改为0或1，则该过程将运行。
以下是整个程序：

以下是我遇到的错误：

这令人困惑，因为我在第38行找不到该代码......
错误似乎围绕代码的 WHEN mrt_opt = 2 THEN 部分。因为（如前所述）如果该选项为0或1，则该过程有效。
我花了很长时间看这个，想要一双新鲜的眼睛。
谢谢！
答案 0 :(得分：0)
您在声明中围绕该代码获得了额外的,0)。
搜索并更改以下行：
WHEN mro_opt = 2 THEN
' ,ifnull(sum(MRO_PC_3P),0),0) as MRO_PC
到此：
WHEN mro_opt = 2 THEN
' ,ifnull(sum(MRO_PC_3P),0) as MRO_PC
