public final class AllOrAnyExpression extends AbstractSingleEncapsulatedExpression
An ALL conditional expression is a predicate that istrue
if the comparison operation istrue
for all values in the result of the subquery or the result of the subquery is empty. An ALL conditional expression isfalse
if the result of the comparison isfalse
for at least one row, and is unknown if neithertrue
norfalse
.An ANY conditional expression is a predicate that is
true
if the comparison operation istrue
for some value in the result of the subquery. An ANY conditional expression isfalse
if the result of the subquery is empty or if the comparison operation isfalse
for every value in the result of the subquery, and is unknown if neithertrue
norfalse
. 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.BNF:all_or_any_expression ::= {ALL|ANY|SOME}(subquery)
