SQL - Inserting a row and returning primary key

Question

I have a little witty problem. Say, I inserted a row with some data in a table where a primary key is present. How would one \"SELECT\" the primary key of the row one just i

Answer 1

select MAX(id_column) from table

That, in theory, should return you that last inserted id. If it's a busy database with many inserts going on it may not get the one you just did but another.

Anyhow, an alternative to other methods.
