Trigger Status

Have you ever spent hours looking at an issue only to have your investigation hindered by a trigger?  I know I have and on more than one occasion!  This little script can be added to a SQL Agent Job and scheduled as you require to email an operator with a list of all triggers for all user databases, the table they are on and the status.

Remember, fully understanding your environment, the features you use and what is the norm is something that pays dividends when things go bad.

Enjoy!
