What you have done so far?

And, more importantly, what is your DB design?
If you only have one table, not at least two tables and probably three or more, then it's a bad design that will only be made worse by trying to do this query.

Bad design. Makes it tough to create a good query.
Your only real choice is 5 separate queries, though you could use a UNION to make it *look* like one query.
