Subject [jira] Created: (OPENJPA-356) DB2 requires CASTs when parameters appear in SELECT clause
Date Fri, 07 Sep 2007 19:27:30 GMT
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.
