If i put a trigger which executes before some data is inserted/udpated into a table.
and if that trigger calls a function, which raises exception, will the insertion of data into the table will be succesfull or not ?

That depends on what kind of error it is and whther you use TRY..CATCH.. to trap it or not.

I am wondering how you can write a trigger that would be fired before inserting/updating rows into a table.
If i am not wrong a trigger will fire either after or instead of the event that actually fired the trigger.
Regards,
Sam.

If you want "before" you must use "instead" and then perform the functions you want to do before the update/delete/insert is performed and then perform the update/delete/insert in code. That's how I understand it.

Yes, you are correct Sam. The OP would have to use an INSTEAD OF trigger and then do the actual insert/update themselves.

Thankyou. I just realized it.
It's all about improvising and using the same thing it in different ways.
