Netezza queries returning "TEIID30328 Unable to evaluate A.IntKey: No value was available" ------------------------------------------------------------------------------------------ Key: TEIID-2564 URL: https://issues.jboss.org/browse/TEIID-2564 Project: Teiid Issue Type: Bug Components: Query Engine Affects Versions: 8.4 Reporter: Warren Gibson Assignee: Steven Hawkins Attachments: server.log Netezza queries returning "TEIID30328 Unable to evaluate A.IntKey: No value was available". Queries involved all use HAVING. The log file is attached. A couple example queries are: SELECT A.INTKEY, A.STRINGNUM FROM BQT1.SMALLA AS A WHERE CONVERT(LONGNUM, STRING) = 8 GROUP BY A.INTKEY, A.STRINGNUM HAVING A.STRINGNUM = (SELECT MAX(B.STRINGNUM) FROM BQT1.SMALLA AS B WHERE A.INTKEY = B.INTKEY SELECT A.INTKEY, A.FLOATNUM FROM BQT1.SMALLA AS A WHERE NOT (A.INTNUM IS NULL) GROUP BY A.INTKEY, A.FLOATNUM HAVING A.FLOATNUM = (SELECT MIN(B.FLOATNUM) FROM BQT1.SMALLA AS B WHERE A.INTKEY = B.INTKEY Analysis from engineering: The issue is happening when a the subquery is converted to a join (this is happening under to covers based upon the costing of the subquery plan) and the correlated column is a grouping expression. If the subplan is not converted to a join or the correlated column is not a grouping expression, then there is no issue.
