DB2 requires CASTs when parameters appear in SELECT clause
----------------------------------------------------------

                 Key: OPENJPA-356
                 URL: https://issues.apache.org/jira/browse/OPENJPA-356
             Project: OpenJPA
          Issue Type: Bug
          Components: jdbc
    Affects Versions: 1.0.0, 0.9.7, 0.9.6, 0.9.0
         Environment: Kodo JDO
            Reporter: Patrick Linskey
             Fix For: 1.1.0


When executing a query that selects a literal value, OpenJPA converts the 
literal into a parameter in the SQL SELECT clause. In DB2, such parameters must 
be CAST to the appropriate type.

Note that this is not reproducible via OpenJPA's JPA bindings, as JPQL does not 
allow literals in the SELECT clause. However, the OpenJPA query parse trees do 
allow this syntax, and Kodo's JDO bindings allow such constructs.
