The SQL NOT EXISTS Operator will act quite opposite to EXISTS Operator. It is used to restrict the number of rows returned by the SELECT Statement.

Note that you can use SELECT , SELECT column, SELECT aconstant, or anything in the subquery. The results are the same because MySQL ignores the select list appeared in the SELECT clause..
