Steven Hawkins updated TEIID-2189:
----------------------------------

               Priority: Minor  (was: Major)
    Bugzilla References: https://bugzilla.redhat.com/show_bug.cgi?id=855017  (was: https://bugzilla.redhat.com/show_bug.cgi?id=855017)


Our logic isn't really amenable to handling || differently than concat.  This would probably have to be implemented as having both || and concat map to concat2.  That by itself is not a large change especially if it's enabled via a system property and affects the system globally (user queries transformations etc.)  If that's not desirable then we need more information.
