SELECT column(s)
FROM table
WHERE column(s) operator ANY
(SELECT column(s) FROM table WHERE condition);

`ANY` subquery can be regarded as a generalization of `IN` subquery. And `IN`
subquery is a special case of `ANY` subquery whose operator should be "=". The
expression evaluates to `true` if the comparison between `column(s)` and any
row in the subquery's result set returns `true`.
