From "Yip Ng (JIRA)" <derby-...@db.apache.org>
Subject [jira] Commented: (DERBY-1784) When qualifying a column name with its synonym name in the select list, Derby throws SQLSTATE 42X04.
Date Sat, 02 Sep 2006 18:02:23 GMT
    [ http://issues.apache.org/jira/browse/DERBY-1784?page=comments#action_12432297 ] 
            
Yip Ng commented on DERBY-1784:
-------------------------------

Yes,  the resolution code may be move up to its caller ColumnReference's bindExpression()
instead.  This method will eventually call FromList's bindColumnReferences().  I'll resubmit
the patch but need to rerun derbyall to make sure.

> When qualifying a column name with its synonym name in the select list, Derby throws
SQLSTATE 42X04.
