             Summary: rewrite skipped
                 Key: TEIID-3011
                 URL: https://issues.jboss.org/browse/TEIID-3011
             Project: Teiid
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: Query Engine
    Affects Versions: 7.7
            Reporter: Steven Hawkins
            Assignee: Steven Hawkins
             Fix For: 8.7.1, 8.7


The rewrite of a set predicate is being bypassed when all of the in values are constants, but when pushed through a view with a convert on the left expression there is still optimizations that can be performed.

For example:

select * from (select e1, e2 from pm1.g1 union all select convert(e2, string), e2 from pm1.g2) x where e1 in ('1', '2')

such that e1 is string and e2 is integer, we expect that the second branch will have criteria of the form "e2 in (1, 2)" - with no conversion.
