Newbie question

Hi, I am new to reporting services, and I wonder if I am limited to sql queries or can I program reports? This might sound stupid but I have never had to write reports so I am not sure what to look for.

I've been using RS for about 3 months now. You can use SQL queries to populate your datasets, but you can write code to "dynamically" generate those queries.

I'd suggest picking up one of the few RS books out there, like the "Reporting Services in Action" or "Hitchhikers Guide.." books.
