There are a couple of other things that I don't care for in this example in addition to the large list of my my my's.

• Calling functions with &. It isn't needed in most cases, none of which I see in this code.
• Generating raw SQL without binding columns. There are very few cases where you should not bind columns. This isn't one of them.
• Using the results of $#{ $data } with a while loop. foreach, last and next are your friends.

Titles consisting of a single word are discouraged, and in most cases are disallowed outright.

Read Where should I post X? if you're not absolutely sure you're posting in the right place.
