SQL should be in every programmer's bag of tricks. True, it's not Turing complete, but what it does, it does well. I classify it as one of those mind stretching languages. It forces you to think in sets, and complex queries have very much an inside out flavor. From the practical point of view, a good knowledge of SQL gives you a decided advantage over those who depend on an ORM.
