SQL - INSERT and catch the id auto-increment value

Question

What is the best way to get the auto-id value in the same SQL with a SELECT?

A forum said adding this \"; has Return Scope_Identity()\"
in the end

Answer 1

Be very careful: Apparently select nextval(seq) does not work in high concurrency - some other connection can insert between the time when you inserted and the time when you called select nextval(seq). Always test such code in high concurrency test harnesses.
