You could also try EXISTS
:
SELECT EXISTS(SELECT * FROM table1 WHERE ...)
and per the documentation, you can SELECT
anything.
Traditionally, an EXISTS subquery starts with SELECT *, but it could begin with SELECT 5 or SELECT column1 or anything at all. MySQL ignores the SELECT list in such a subquery, so it makes no difference.
