If you haven't read it, I recommend Joe Celko's latest book "Thinking in Sets". It is an excellent resource and he recalls the basisc -- that we work with relational structures and not files.
Again, Celko explains the differences between SQL as a declarative language and procedural ways to solve a problem and why it is important to understand the differences. He shows the historic backgrounds (chapter 1 to 3). This helps a lot to understand why many solutions are procedural even if a declarative one would be more efficient.
