Nathan Deckard commented on HHH-1050:
-------------------------------------

Matt,

I just used UNION in an HQL query, and observed the same behavior as Trevor (the query gets truncated at UNION). Could you please describe the syntax that you used to get it to work? Also, what version of hibernate are you using?

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
