    [ https://issues.apache.org/jira/browse/DERBY-3765?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12611579#action_12611579 ] 

Knut Anders Hatlen commented on DERBY-3765:
-------------------------------------------

I think this is intentional behaviour and not a bug. See Bryan Pendleton's interpretation of the SQL standard for this case here: https://issues.apache.org/jira/browse/DERBY-2351?focusedCommentId=12505472#action_12505472

Also see Yip Ng's comment explaining that such a query is ambiguous: https://issues.apache.org/jira/browse/DERBY-2351?focusedCommentId=12473871#action_12473871
