Sorry. Maybe my first post question was unclear enough.

I have two big tables. I want to compare the two table content to see if they are identical. If they are not, then I should exchange their content.

Please tell me how I can do these two steps using SQL. And for the second step, if I am not allowed to create a temp table, how can I do it?

Thanks.
