Avoid External Dependencies in SQL Server Triggers

I sometimes want to perform auditing or other actions in a trigger based on some criteria. More specifically, there are a few cases that may warrant an e-mail; for example, if a web sale takes place that requires custom or overnight shipping and handling. It is tempting to just add code to the trigger that sends an e-mail when these criteria are met. But this can be problematic for two reasons: (1) your users are waiting for that processing to occur, and (2) if you can't send the e-mail, how do you decide whether or not to roll back the transaction, and how do you bring the problem to the attention of the administrator?

This tip shows how to use INSTEAD OF triggers to handle these DML operations on views.
