sql server - Reference where clause in instead of update trigger -

Is there a way to reference the clause instead of triggering the update?

** More information **

I am trying to get this issue:.

This amazing product will try to update those rows that have changed or who are not present. Since I do not need any care about existing data / if I can modify it that due to being more normal the update will be going on and I can move forward.

The well-deleted table shows the data that you selected with the clause, so if You know where the pen is at 1, then you know the values ​​you ask? But know exactly where it is, no one. The only data available in the trigger is data in the table before and after the update statement.

It may be that if you have expressed that it is easy to help you, then the intrigue you want to trigger is easy.
