Steven Hawkins updated TEIID-4451:
----------------------------------
      Component/s: Query Engine
    Fix Version/s: 9.1
                   9.0.5


This is a general issue with the conversion of a plan that calls a subquery repeatedly into a semi-join plan.  If the projection is an aggregate, then the parent plan isn't finding the value.
