             Summary: Key usage can convert an outer join into an inner join
                 Key: TEIID-2107
                 URL: https://issues.jboss.org/browse/TEIID-2107
             Project: Teiid
          Issue Type: Bug
          Components: Query Engine
    Affects Versions: 7.4
            Reporter: Steven Hawkins
            Assignee: Steven Hawkins
            Priority: Critical
             Fix For: 8.1


If a left outer join is against a table/view with a index and the join is using all equi-join predicates and there is an additional predicate beyond what is in the index, then the join will be erroneously converted to an inner join.
