-------------------------------------

             Summary: Non-pushed subquery may have evaluatable predicates not pushed
                 Key: TEIID-5529
                 URL: https://issues.jboss.org/browse/TEIID-5529
             Project: Teiid
          Issue Type: Bug
          Components: Query Engine
            Reporter: Steven Hawkins
            Assignee: Steven Hawkins
             Fix For: 12.0


For example, a source that does not support lower nor correlated subqueries and a query like:

SELECT array_agg((select intkey from bqt1.smallb where stringkey = lower(a.stringkey))) from bqt1.smalla a

will not push stringkey =  lower(a.stringkey) to the n-many subquery, even though it can be pre-evaluated with the correlated value.
