Integration

Hi!

like it is written in the Toplink JPA Extensions reference Toplink supports using named parameters in native queries.

See example from http://www.oracle.com/technology/products/ias/toplink/jpa/resources/toplink-jpa-extensions.html:
Example 1-11 Specifying a Named Parameter With #
Query queryEmployees = entityManager.createNativeQuery(
"SELECT OBJECT(emp) FROM Employee emp WHERE emp.firstName = #firstname"
);
queryEmployeeByFirstName.setParameter("firstName", "Joan");
Collection employees = queryEmployees.getResultList();


But I want to use "#" in the SQL statement so I want to disable this parameter binding somehow and let the query just execute the SELECT statement I deliver.

I have tried to add the property
<property name="toplink.jdbc.bind-parameters" value="false"/>
into the persistence.xml and I have also tried to add the query hint
query.setHint(TopLinkQueryHints.BIND_PARAMETERS, HintValues.FALSE);
but none of them prevents the # to be uses as a paramter. this causes the exception:

Exception [TOPLINK-6132] (Oracle TopLink Essentials - 9.1 (Build b22)): oracle.toplink.essentials.exceptions.QueryException
Exception Description: Query argument ######' not found in list of parameters provided during query execution.
Query: ReadAllQuery(de.merck.compas.material.SimilarLocalMaterialListItemBV)

The SQL Statement is
SELECT * FROM TABLE (
CAST ( RCGC.PHA_P_COMPASMDM.LookupSimilarMats
( 'COC003','10021500150000000997','30','30','040','standard','','001001','001001','123456','##########','X','X','X','X','U' )
AS RCGC.PHA_COMPAS_SIMILAR_MATS ) )


I am using the latest Toplink essentials build together with an Oracle 9.2i DB in a Java SE web application.


Can anyone give me a little hint what to do?


Thanks and best regards,
Alex
