Dyre Tjeldvoll commented on DERBY-3257: --------------------------------------- Fwiw: I applied the first version of your patch and verified that the repro worked correctly. I also ran all the test with the patch. I saw no failures. +1 to commit. And thanks for addressing this - one less regression to worry about :) > SELECT with HAVING clause containing OR conditional incorrectly return 1 row > - should return 2 rows - works correctly with 10.2 DB > ---------------------------------------------------------------------------------------------------------------------------------- > > Key: DERBY-3257 > URL: https://issues.apache.org/jira/browse/DERBY-3257 > Project: Derby > Issue Type: Bug > Components: SQL > Affects Versions: 10.3.1.4, 10.3.2.1, 10.4.0.0 > Reporter: Stan Bradbury > Assignee: Kathey Marsden > Attachments: 42X24_error.sql, d3257_doNOTCommit.patch, > derby-3257_diff.txt, derby-3257_diff2.txt, derby-3257_plan_10.2.txt, > derby-3257_plan_10.4.txt, derby-3257_stat.txt, TestHaving.java > > > Attached program demonstrates the problem.
