public final class AllOrAnyExpression extends AbstractSingleEncapsulatedExpression
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.
