[ http://issues.apache.org/jira/browse/DERBY-883?page=comments#action_12432263 ] Manish Khettry commented on DERBY-883: --------------------------------------
I think the issue can be closed. I'm not sure if we want to allow the use of grouping expressions in the having clause; i.e. select c+1, count(*) from t group by c+1 having c+1 > 1; I only have access to mysql, which doesn't allow this but does let you do select c, count(*) from t group by c having c > 1; If we do, then we need another bug or a subtask of this issue. > Enhance GROUP BY clause to support expressions instead of just column > references. > --------------------------------------------------------------------------------- > > Key: DERBY-883 > URL: http://issues.apache.org/jira/browse/DERBY-883 > Project: Derby > Issue Type: New Feature > Components: SQL > Affects Versions: 10.1.2.1, 10.2.1.0 > Environment: JDK 1.5.0_05 > Reporter: Lluis Turro > Assigned To: Manish Khettry > Fix For: 10.3.0.0 > > Attachments: 883.patch.txt, 883.patch3.txt, 883.patch4.txt, > 883.patch5.txt, 883.patch6.txt, 883.patch6.txt, 883.patch7.txt > > > This select would return an error syntax on finding "(" after month if group > by clause: > select idissue, month(creation), year(creation), count(distinct idissue) > where > .... > group by idissue, month(creation), year(creation) -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
