You can specify a scalar subquery as an operand of a scalar predicate in the WHERE, HAVING, and QUALIFY clauses of a query.

The following example specifies a scalar subquery (SELECT AVG(price)…) as an operand in its WHERE clause.

     SELECT category, title, price
     FROM movie_titles AS t2
     WHERE (SELECT AVG(price) 
            FROM movie_titles AS t1
            WHERE t1.category = t2.category)<(SELECT AVG(price)
                                              FROM movie_titles);
