Michael Dick updated OPENJPA-511:
---------------------------------
Attachment: (was: OPENJPA-511.patch.txt)
> Unable to execute native queries which start with the WITH keyword.
> --------------------------------------------------------------------

> Key: OPENJPA-511
> URL: https://issues.apache.org/jira/browse/OPENJPA-511
> Project: OpenJPA
> Issue Type: Bug
> Components: jdbc
> Affects Versions: 1.0.1
> Environment: DB2
> Reporter: Michael Dick
> Assignee: Michael Dick
> Fix For: 1.1.0

> Attachments: OPENJPA-511.patch.txt

> Some databases support using WITH ${var} AS (SELECT . . .) SELECT ${var}, . .
> . The variable may be used in a future select statement.
> Currently OpenJPA checks whether a native query begins with "select" (case
> insensitive) and throws an exception if an application calls
> getSingleResult() or getResultList() if select isn't found. As I understand
> it the WITH statement may only be used in conjunction with a SELECT
> statement, so it should be safe to treat the WITH statement as a select.
> I'm not sure how many databases support this syntax so it might be best to
> limit the support to specific databases.
> The only database to support the WITH statement that I know of is DB2, but
> this may apply to other databases too. Additional documentation can be found
> in the DB2 infocenter :
> http://publib.boulder.ibm.com/infocenter/db2luw/v8/index.jsp?topic=/com.ibm.datatools.sqlbuilder.doc/topics/ruisqlbldrwth.html.
