Hi Team,




It's my first time to use triggers so Is there a way to create a trigger when a specific column gets
updated or inserted (not the whole table)?

Hi Team,
It's my first time to use triggers so....?


So... From SSMS, press the F1 key to get into Books Online. Then search for CREATE TRIGGER and start reading. I'm not being sarcastic here. If it's truly your first time, take the opportunity to teach yourself all about triggers so you won't have to ask such questions in the future. To really do it right, create a test database and some tables to practice writting triggers on so you can actually see what they do.

Triggers can be quite the tripping point in code and if you don't have a very firm grasp on what they actually do and how they work and how to use them, you're going to make some really huge and embarassing mistakes.

RBAR is pronounced ree-bar and is a Modenism for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
Stop thinking about what you want to do to a row... think, instead, of what you want to do to a column.
If you think its expensive to hire a professional to do the job, wait until you hire an amateur. -- Red Adair
