This article does not place the stored procedure instance.

This is the most time-consuming problem I have encountered in developing a stored procedure, and the stored procedure can run, but the result is not what you want,

For a long time, it was found that the ID in this sentence was a curse: SET projectinfoid = (SELECT ID from temp. Project_info p WHERE 1=1 and p.issue_key = Projectkey);

Change to p.id is OK.

To develop good habits, remember to use the X.XX format when writing, and avoid unnecessary errors.
