MongoDB translator issues with aggregate function expressions ------------------------------------------------------------- Key: TEIID-5303 URL: https://issues.jboss.org/browse/TEIID-5303 Project: Teiid Issue Type: Bug Components: Misc. Connectors Affects Versions: 8.7 Reporter: Steven Hawkins Priority: Major Fix For: 12.x 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
