[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-1050) HQL Unions

[Lucas de Oliveira Arantes (JIRA)]

    [ http://opensource.atlassian.com/projects/hibernate/browse/HHH-1050?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=40009#action_40009 ] 

Lucas de Oliveira Arantes commented on HHH-1050:
------------------------------------------------

Same behavior as Nathan and others reported: query gets truncated at the 'union' keyword. Using Hibernate 3.3.2.GA with PostgreSQL 8.4. Query is: 
select pr1.value as val, it1.name as description from ProductPrice pr1, Item1 it1 where pr1.relitem.class = 'Item1' and pr1.relitem.id = it1.id
union
select pr2.value as val, it2.observation as description from ProductPrice pr2, Item2 it2 where pr2.relitem.class = 'Item2' and pr2.relitem.id = it2.id

Any plans for this issue to be resolved?
Thanks!

> Add the ability to define unions in HQL.  Support will be initially limited to only:
> 1) scalar queries : select id from Animal union select id from Car
> 2) the same entity : from Animal where ... union from Animal where ...
> Support both UNION and UNION ALL
