addNestedTableGroupJoin
public void addNestedTableGroupJoin(TableGroupJoin join)
Description copied from interface:TableGroup
A nested table group join is a join against a table group, that is ensured to be joined against the primary table reference and table reference joins in isolation, prior to doing other table group joins e.g.select * from entity1 e left join ( collection_table c1 join association a on a.id = c1.target_id ) on c1.entity_id = e.id and c1.key = 1
is modeled asTableGroup( primaryTableReference = TableReference(entity1, e), tableGroupJoins = [ TableGroupJoin( TableGroup( primaryTableReference = TableReference(collection_table, c1), nestedTableGroupJoins = [ TableGroupJoin( TableGroup( primaryTableReference = TableReference(association, a) ) ) ] ) ) ] )
This is necessary to correctly retain the cardinality of an HQL join like e.g.from Entity1 e left join e.collectionAssociation c on key(c) = 1
