[hibernate-issues] [Hibernate-JIRA] Closed: (HHH-3908) Expose way to fully control fetching and result mapping on SQLQuery

Expose way to fully control fetching and result mapping on SQLQuery ------------------------------------------------------------------- Key: HHH-3908 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3908 Project: Hibernate Core Issue Type: New Feature Components: core Reporter: Steve Ebersole Assignee: Steve Ebersole Fix For: 3.6.0.Beta2 Time Spent: 6.1h Remaining Estimate: 0h Currently, in order to fully control fetching in native-sql queries, users must revert to using a named sql query (at least the xml, not sure if the annotations variety supports as well). We alreasy have all the objects/contracts in place to handle this for the named queries, just need to clean-up and properly document them. The current API calls to deal with this are the overloaded SQLQuery#addJoin methods. Ideally I'd see these changed to return the representation of the join-fetch to be configured; but addJoin already defines a return : the query itself :( So probably we will need new methods like addFetch: 1) public JoinFetch addFetch(String alias, String ownerAlias, String ownerProperty) 2) public JoinFetch addFetch(String alias, String ownerAlias, String ownerProperty, LockMode lockMode) interface JoinFetch { public void addPropertyMapping(String propertyName, String sqlAlias); } This can be expanded to the "root returns" as well (currently the overloaded #addEntity methods): public RootReturn addRoot(String alias, Class entityClass) etc... ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Example ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ SQLQuery query = session.createSQLQuery( "select c.cust_id as cid, " + " c.cust_name as cname, " + " o.order_id as oid, " + " o.order_num as onum " + " from customer c " + " inner join orders o " + " on c.cust_id = o.cust_id" ); query.addRoot( "c", Customer.class ) .addPropertyMapping( "id", "cid" ) .addPropertyMapping( "name", "cname" ); query.addFetch( "o", "c", "orders" ) .addPropertyMapping( "id", "oid" ) .addPropertyMapping( "orderNumber", "onum" ); ...
