Using the T-SQL OUTPUT Clause

Chad Callihan doesn’t make two calls:

Are you familiar with the OUTPUT clause in SQL Server? It can be used with commands like INSERT, UPDATE, DELETE, and MERGE. It can also be used with setting variables in stored procedures. Using the tried and true StackOverflow2013, we’ll narrow it down today to focus on how INSERT/DELETE are typically used for logging table changes as well as an example of how to use OUTPUT with stored procedures.

For really busy transactional systems, this provides a nice boost over making an update and then selecting the new values.
