推荐答案
我愿意是您的cmd返回的内容与int类型不兼容. br/>
存储的proc的返回类型是什么?创建一个变量,首先将结果分配给该变量.然后设置一个断点,看看返回了什么.
干杯.
I''d be willing to be that your cmd is returning something that is not compatible with the int type.
What is the return type on the stored proc? Create a variable, assign the result to that first. Then set a breakpoint and see what''s returned.
Cheers.
