             Summary: Inappropriate aggregate pushdown over nested table join
                 Key: TEIID-5934
                 URL: https://issues.redhat.com/browse/TEIID-5934
             Project: Teiid
          Issue Type: Bug
          Components: Query Engine
            Reporter: Steven Hawkins
            Assignee: Steven Hawkins
             Fix For: 14.0


Related to TEIID-5932, a query with multiple lateral joins and a group by is optimized incorrectly.  Altering the unit test query to:

{code}
SELECT xt.event_id, count(*) FROM tbl AS d, 
    TABLE (select d.event_id from tbl limit 1) xt
      LEFT JOIN TABLE (select tbl.str as some_col from tbl where str = 'a' || d.str) xt2
      ON xt.event_id = -1
group by xt.event_id
{code}

Results in a processing error because the initial pushdown for tbl only selects count star and does not select tbl.str.
