Shawn Kerstetter commented on HHH-951:
--------------------------------------

I should include the log files depicting the error:

     [exec] 15:58:16,484 DEBUG [SQL] select * from ( select testhhh951x0_.primaryKey as primaryKey417_, testhhh951x0_.TRANID as TRANID417_, testhhh951x0_.tranid as tranid417_ from TestHHH951 testhhh951x0_ ) where rownum <= ?
     [exec] 15:58:16,593 WARN  [JDBCExceptionReporter] SQL Error: 918, SQLState: 42000
     [exec] 15:58:16,593 ERROR [JDBCExceptionReporter] ORA-00918: column ambiguously defined

*ALSO* note that the work around is really simple, just use UPPERCASE column names.
