Subqueries and the ALL test

The ALL test is used with one of the SQL comparison operators (=, >, <, >=, <=, !=, <>, !>, !<) to compare a single value to the data values produced by the subquery. To perform the test, SQL uses the specified comparison operator to compare the test value to each data value in the result set. If all the comparisons yield TRUE results, the ALL test returns TRUE.
