[jira] [Commented] (DERBY-6689) Assert failure/NPE when using ROW_NUMBER in MERGE ... INSERT

["Knut Anders Hatlen (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/DERBY-6689?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14087362#comment-14087362 ] 

Knut Anders Hatlen commented on DERBY-6689:
-------------------------------------------

I believe the failing statement is not allowed by the standard. See SQL 2011, part 2, 6.10 <window function>, syntax rule 4.
