Subject [jira] [Commented] (DERBY-5933) SQL sorting error
Date Mon, 24 Sep 2012 20:26:08 GMT

    [ https://issues.apache.org/jira/browse/DERBY-5933?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13462085#comment-13462085
] 

Dag H. Wanvik commented on DERBY-5933:
--------------------------------------

I checked the resulting tree after the preprocess phase of optimization, and the column reference
to A1 is indeed already labeled  (4,1). The enclosed log file shows this to be the case after
end of the optimization phase. The problematic labelling happens during preprocess time, at
which time the flattening occurs.

> Hello 
> I have a simple database with 100 records.
> I am running a SQL query from Netbeans GUI though JDBC
> This query was generated by Hibernate ORM.
> In certain circumstances the result rowset is not sorting.
> When I use  condition morefld2_.mf_id in (5) the result is unsortable.
> When I use  condition morefld2_.mf_id in (5,0) the result is sorting properly.
