Subject [jira] Resolved: (DERBY-2887) NULLS FIRST / LAST for ORDER BY
Date Wed, 26 Sep 2007 04:51:50 GMT

     [ https://issues.apache.org/jira/browse/DERBY-2887?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Bryan Pendleton resolved DERBY-2887.
------------------------------------

    Resolution: Fixed

I read the DatabaseMetaData javadoc for a while, and I didn't see
any reason to believe that our current implementation should
change due to the NULLS FIRST/LAST support. The DatabaseMetaData
javadoc doesn't specifically mention the impact of NULLS FIRST/LAST,
but since the DatabaseMetaData methods are supposed to describe
the behavior of the database system as a whole, and the NULLS
FIRST/LAST is a query-specific behavior, it seems reasonable that
the DatabaseMetadata methods should not take NULLS FIRST/LAST
into account.

So I think it's safe to re-resolve this issue.
