The most powerful bug

This is a bug I encountered when I was working on the project. I haven't processed it all day! Seeking for help is still not handled! I have handled it myself!

I personally think there is a problem with the ing file, but I didn't find it! The processing method is to fill in the int type data of the corresponding table of the database!
