Key: DERBY-3257
URL: https://issues.apache.org/jira/browse/DERBY-3257
Project: Derby
Issue Type: Bug
Affects Versions: 10.3.1.4, 10.3.1.5, 10.4.0.0
Reporter: Stan Bradbury
Attachments: TestHaving.java
Attached program demonstrates the problem. Only one count is returned
(matching CODE= GBR) - the count of CODE=CHA is not returned. Works fine with
versions 10.1 and 10.2 or if program is run using 10.3 jars and 10.2 database
(soft upgrade).
Query:
SELECT COUNT(t0.ID) FROM CTS1.TEST_TABLE t0
GROUP BY t0.CODE
HAVING (t0.CODE = 'GBR' OR t0.CODE = 'CHA') AND t0.CODE IS NOT NULL
Incorrect results (see last line):
Database product: Apache Derby
Database version: 10.3.1.5 - (579866)
Driver name: Apache Derby Embedded JDBC Driver
Driver version: 10.3.1.5 - (579866)

Correct results:
Database product: Apache Derby
Database version: 10.2.2.0 - (485682)
Driver name: Apache Derby Embedded JDBC Driver
Driver version: 10.2.2.0 - (485682)
