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?
