An ALL conditional expression is a predicate that is true if the comparison operation is true for all values in the result of the subquery or the result of the subquery is empty. An ALL conditional expression is false if the result of the comparison is false for at least one row, and is unknown if neither true nor false.

An ANY conditional expression is a predicate that is true if the comparison operation is true for some value in the result of the subquery. An ANY conditional expression is false if the result of the subquery is empty or if the comparison operation is false for every value in the esult of the subquery, and is unknown if neither true nor false. The keyword SOME is synonymous with ANY. The comparison operators used with ALL or ANY conditional expressions are =, <, <=,>, >=, <>. The result of the subquery must be like that of the other argument to the comparison operator in type.
