public class AllOrAnyExpressionStateObject
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.
