The T-Sql Merge statement, introduced in SQL 2008, is powerful, versatile, and performant. However, it is also one of T-SQL's least understood statements. Most DBAs know they can use It to insert, update, and delete data in a target table in a single transaction, generally outperforming separate statements. Fewer know, however, that it can be used to load slowly changing dimensions, facilitate auditing, and for many other uses. Come to the user group meeting and learn the in and outs of T-SQL Merge. I'll even show you how to write complex Merge statements with lightning speed.
