T - the type of the selection item.public interface Subquery<T> extends AbstractQuery<T>, Expression<T>
Subquery interface defines functionality that is
specific to subqueries.
A subquery has an expression as its selection item.| Modifier and Type | Method and Description |
|---|---|
<X,Y> CollectionJoin<X,Y> |
correlate(CollectionJoin<X,Y> parentCollection)
Create a subquery collection join object correlated to a
collection join object of the enclosing query.
|
<X,Y> Join<X,Y> |
correlate(Join<X,Y> parentJoin)
Create a subquery join object correlated to a join object
of the enclosing query.
|
<X,Y> ListJoin<X,Y> |
correlate(ListJoin<X,Y> parentList)
Create a subquery list join object correlated to a list join
object of the enclosing query.
|
<X,K,V> MapJoin<X,K,V> |
correlate(MapJoin<X,K,V> parentMap)
Create a subquery map join object correlated to a map join
object of the enclosing query.
|
<Y> Root<Y> |
correlate(Root<Y> parentRoot)
Create a subquery root correlated to a root of the
enclosing query.
|
<X,Y> SetJoin<X,Y> |
correlate(SetJoin<X,Y> parentSet)
Create a subquery set join object correlated to a set join
object of the enclosing query.

Subquery<T> |
distinct(boolean distinct)
Specify whether duplicate query results will be eliminated.
|
Set<Join<?,?>> |
getCorrelatedJoins()

Specify the expressions that are used to form groups over
the subquery results.
|
Subquery<T> |
groupBy(List<Expression<?>> grouping)

|
Subquery<T> |
having(Predicate... restrictions)
Specify restrictions over the groups of the subquery
according the conjunction of the specified restriction
predicates.
|
Subquery<T> |
select(Expression<T> expression)
Specify the item that is to be returned as the subquery
result.
|
Subquery<T> |
where(Expression<Boolean> restriction)

to the specified boolean expression.
|
Subquery<T> |
where(Predicate... restrictions)
