[jira] Commented: (DERBY-1894) SQLSTATE 42X10 occurs when qualifying a column with a synonym in ORDER BY clause

["Mamta A. Satoor (JIRA)" <de...@db.apache.org>]

    [ http://issues.apache.org/jira/browse/DERBY-1894?page=comments#action_12439244 ] 
            
Mamta A. Satoor commented on DERBY-1894:
----------------------------------------

Yip, I reviewed the code and it looks good to me. For the tests, should we have a test case where a correlation name is used in order by? May be there is already such a test or may be this test will not test the changes you made but here is a test case based on the sql script included in this Jira entry
set schema test2;
select testtable.id as c1 from testtable order by c1;
