[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-5220) Unit tests related to HHH-5063 and HHH-5135 fail on some dialects

[Steve Ebersole (JIRA)]

    [ http://opensource.atlassian.com/projects/hibernate/browse/HHH-5220?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=37124#action_37124 ] 

Steve Ebersole commented on HHH-5220:
-------------------------------------

In reference to HHH-5063 at least, I wanted to point out the new dialect methods I added:
{code}
/**
 * Does this dialect support `count(a,b)`?
 *
 * @return True if the database supports counting tuples; false otherwise.
 */
public boolean supportsTupleCounts() {
    return false;
}

/**
 * Does this dialect support `count(distinct a,b)`?
 *
 * @return True if the database supports counting disintct tuples; false otherwise.
 */
public boolean supportsTupleDistinctCounts() {
    // oddly most database in fact seem to, so true is the default.
    return true;
}
{code}

Note, that I said it is odd that most databases seem to "supportsTupleDistinctCounts" only because most in fact seem to not "supportsTupleCounts".  The ANSI SQL spec in fact says both should be valid.

> The fixes for HHH-5063 and HHH-5135 are OK, but there are problems when using particular dialects.
> For example:

> There may be other dialects that are affected as well.
