[jira] Commented: (DERBY-4045) Subquery causes error: 'updateString' not allowed because the ResultSet is not an updatable ResultSet

["Dag H. Wanvik (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/DERBY-4045?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12724675#action_12724675 ] 

Dag H. Wanvik commented on DERBY-4045:
--------------------------------------

Since this limitation has now been documented, I intend to resolve this as a "not a bug" in a day or two.
Feel free to file an improvement request for this particular query form, since Knut has established that it might work.

> Embedded Derby (don't know about client) demoted an updatable result set apparently due to a nested query.
> select * from orders where (orders.recordno = (select max(orders.recordno) from orders))
> Fix if possible. 
> If it can't be fixed, the documentation should be changed.
