Steven Hawkins commented on TEIID-5193:
---------------------------------------
[~rareddy] Our logic typically moves predicates from the having clause to the where if
they do not involve aggregates. The issue here must be that the subquery must prevent
that. I can address this in the engine.
Osisoft translator - correlated subquery on HAVING clause fails
---------------------------------------------------------------
Key: TEIID-5193
URL:
https://issues.jboss.org/browse/TEIID-5193
Project: Teiid
Issue Type: Bug
Components: JDBC Connector
Affects Versions: 8.12.x-6.4
Reporter: Andrej Šmigala
Assignee: Ramesh Reddy
Running a query with a correlated subquery in a HAVING clause, such as
{code:sql}
SELECT INTKEY, STRINGKEY
FROM BQT1.SMALLA AS A
WHERE NOT (INTKEY IN (10))
GROUP BY INTKEY, STRINGKEY
HAVING INTKEY = (SELECT MIN(STRINGKEY) FROM BQT1.SMALLA AS B WHERE A.INTKEY = B.INTKEY)
{code}
fails on the datasource with
bq. com.osisoft.rdsa.RdsaException: [PIOLEDBENT] HAVING condition cannot be
nonaggregate.
This seems to be an issue on the Osisoft PI datasource side, as running the query
directly against the datasource produces the same failure.
