Incorrect aggregate rewriting on DB2/AS400 using UDF
----------------------------------------------------
Key: TEIID-2202
URL: https://issues.jboss.org/browse/TEIID-2202
Project: Teiid
Issue Type: Bug
Components: JDBC Connector, Query Engine
Affects Versions: 7.7.1
Reporter: Hisanobu Okuda
Assignee: Steven Hawkins
When I run the following query, the count(*) in the middle inline view, gets rewritten as
a sum and a count in the most inner inline view. This has something to do with my the
parseDate_ UDF. This is a change from EDS 5.2 where it worked correctly. I've included
logs from both for contrast.
Query:
{code}
SELECT
examiner,
exam_date,
exam_date_code,
num_claims,
company_id,
1 AS enterprise_id
FROM
(
SELECT
examiner,
parseDate_(exam_date_code) AS exam_date,
exam_date_code,

SELECT
CASE

AND (ME4.APRUSR <> ' ')
THEN
