The EXISTS quantifier is supported as the predicate of a search condition in a WHERE clause.

EXISTS tests the result of the subquery. The subquery is performed for each row of the table specified in the outer query when the subquery is correlated.

If the subquery returns response rows, then its WHERE condition is satisfied.
