public class QueryStructure<T> extends Object implements Serializable
CriteriaQuery
and
Subquery
.
Note the ORDER BY specs are neglected here. That's because it is not valid
for a subquery to define an ORDER BY clause. So we just handle them on the
root query directly...Constructor and Description |
