             Summary: MongoDB translator issues with aggregate function expressions
                 Key: TEIID-5303
                 URL: https://issues.jboss.org/browse/TEIID-5303
             Project: Teiid
          Issue Type: Bug
            Reporter: Steven Hawkins
            Assignee: Steven Hawkins


MongoDB queries involing expressions with aggregate functions in the select or having clauses will fail.  It appears that another projection phase is needed to handling those computations as they are not valid in the group operation.

For example, these result in exceptions:

SELECT min(e1)+1, e2 FROM TIME_TEST GROUP BY e2
SELECT min(e1), e2 FROM TIME_TEST GROUP BY e2 HAVING year(e2) + count(\*) = 2
