public final class AllOrAnyExpression
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 result 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.
