Subject [jira] [Commented] (DERBY-5369) Restricted Table Function support should pass NOT EQUAL restrictions to initScan
Date Wed, 21 Mar 2012 18:51:41 GMT

    [ https://issues.apache.org/jira/browse/DERBY-5369?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13234852#comment-13234852
] 

Rick Hillegas commented on DERBY-5369:
--------------------------------------

As I see it, this is an improvement to a feature which makes the feature more usable. The
crucial documentation change is in the public api javadoc and that is part of the patch. Thanks.

> Restricted Table Function support should pass NOT EQUAL restrictions to initScan.  Currently
any "!=" or "<>" constraints on the SQL used in the WHERE clause of a SELECT on a Restricted
Table Funtion are not passed to the initScan method.  These can be useful depending on how
the Restricted Table Function is implemented.
