Sir, I doubt that you have a table with three columns with the same
name. If I am wrong, then your copy is MySQL is broken.
If your table structure is what I think it is (It's impossible to be
sure from your description), it's going to cause you a lot of
problems. Get a book on relational database design and learn to
normalize tables. In the interim, if you post a description of what
you are trying to do, there are a number of active contributors here
who can make suggestions for a schema.
