Welcome to the CodeIgniter forums.

Please try to remember to wrap your code in [code][/code] tags.

If you could show a bit more code to give us an idea of the context of the code, someone might be able to help you a bit better. At the moment, I don't understand what you're asking.

Fuzzy already covered the formalities about code tags, so I won't repeat that part

Are you trying to do this in a single query instead of 3 or what? What do you mean by 'good query function'?
