             Summary: Vertica translator uses incorrect push down of WEEK function
                 Key: TEIID-4003
                 URL: https://issues.jboss.org/browse/TEIID-4003
             Project: Teiid
          Issue Type: Bug
            Reporter: Andrej Šmigala
            Assignee: Steven Hawkins
             Fix For: 8.12.5


TEIID-3282 changed the semantics of the WEEK function to use the iso behaviour.

The Vertica database has WEEK_ISO function that returns the iso week, but the translator does not have that alias set.

This results in the query (the datevalue in question is 2000-12-31)
{code:sql}
select week(datevalue) from source.largea where intkey = 365
{code} 
to return 54, when the correct value is 52.
