             Summary: Copy criteria within a left outer join removes predicates
                 Key: TEIID-3236
                 URL: https://issues.jboss.org/browse/TEIID-3236
             Project: Teiid
          Issue Type: Bug
          Components: Query Engine
    Affects Versions: 8.4
            Reporter: Steven Hawkins
            Assignee: Steven Hawkins
             Fix For: 8.10


With a query such as:

select bqt1.smalla.intkey from bqt1.smalla inner join (select bqt3.smalla.intkey from bqt2.smalla left outer join bqt3.smalla on bqt2.smalla.intkey = bqt3.smalla.intkey and bqt3.smalla.intkey = 1) foo on bqt1.smalla.intkey = foo.intkey

where the left outer join is not pushed to the source, we will process it as if  bqt2.smalla.intkey = bqt3.smalla.intkey doesn't exist.

This is somewhat unlikely to occur for user queries as the join predicates are not likely to occur and could easily be simplified.
