[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-4652) em#createQuery(String, Class<?>) must support results returning multiple lines

[Emmanuel Bernard (JIRA)]

    [ http://opensource.atlassian.com/projects/hibernate/browse/HHH-4652?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=34892#action_34892 ] 

Emmanuel Bernard commented on HHH-4652:
---------------------------------------

The JavaDoc wording is a bit unclear but here is the story.
The number of elements returned (column) must be 1, ie List<Address> but not a List<Object[]> where Object[] contains address street and address city.

In other words, multi select queries are not supported by the spec (though could optionally).

The current code disallow results where the number of rows are > 1, which is not the intend.
