推荐答案
这个问题与此无关SQL代码。
它与您放入参数的值有关，特别是记录的ID。
传递的值是什么？这就是调试器非常方便的地方。我建议你学习如何使用它，如何使用断点和检查变量内容。
来自网格的选定值显然不是你认为的值它是。
This problem has nothing to do with the SQL code.
It has to do with the values you're placing into the parameters, specifically, the ID of the record.
What are the values being passed in? That's where the debugger is going to come in very handy. I suggest you learn how to use it, how to user breakpoints and inspect variable contents.
The "selected value" coming from the grid is obviously not the value you think it is.
