------------------------------------
Summary: 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
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.
