Question

This question is in continuation of existing question here.

I need to compare two similar tables in two databases on the same instance and update the data if record exists and insert if not. I planning to use merge as given as answer to above question.

But I want to know whether there is any simple solution to update the entire table with other table without writing all the columns in the SET statement in UPDATE query.

I mean I dont want to write SET t1.col1 = t2.col2, t1.col2=t2.col2 and so on.

Answer 1

There is no simple way to do this besides creating the query dynamically and executing it dynamically, both of which are pure evilness.
