[jira] Updated: (CAY-1376) Certain EJBQL queries have mismatched table aliases

["Dave Dombrosky (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/CAY-1376?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Dave Dombrosky updated CAY-1376:
--------------------------------

    Attachment: testGroupByChainedJoins.patch

Added attachment that shows the problem.  Looks like the tables don't need to be in different schemas, which would explain why the getTablesAlias() fixes didn't resolve the issue.

> On some EJBQL queries, the wrong table aliases are being use to refer to columns.  A similar issue was solved earlier in CAY-1114.  This problem seems to occur when EJBQLTranslationContext.getTableAlias() is called on relationships that span database schemas.
