Dynamic SQL is one of the most powerful tools in the database developer's arsenal. When you need a complex search stored procedure that takes all kinds of parameters (price, category, location, color), dynamic SQL can run extremely quickly by leveraging better indexes. However, when done wrong, it's extremely painful to troubleshoot.
