[Steve Hawkins (JIRA)]

Steve Hawkins updated TEIID-715:
--------------------------------

        Summary: Add support for nulls first/last  (was: Allow the user to set null ordering behavior)
    Description: Add language and pushdown support for nulls first/last  (was: Sources that support order by may have different null ordering behavior than Teiid (which currently treats null as low).  We should support the option for the server to be configured as nulls high, low, always high, or always low.

Connectors will need to indicate the sort mode they support so the appropriate push-down and compensating actions can be taken.)


Changing issue to be specifically about nulls first/last.  

At a later time it may be worthwhile to allow the engine default sorting behavior to be set.
