ABSTRACT
Experience with a platform gives us patterns: common techniques which we can use to solve a number of recurring problems. They also give us anti-patterns: common techniques we often use to solve a number of recurring problems incorrectly. This session will cover a number of anti-patterns related to writing T-SQL code. We will cover each anti-pattern in detail, explaining the problem, why you might reach for the anti-pattern, and better alternatives which won't leave you hurting for performance.
