For the life of me, I can't figure out how to call a simple stored proc taking 1 parameter:


Hibernate version: version 3.1 rc2, Oct 07, 2005


<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC

</class>

<sql-query name="test_SP" callable="true">
<return alias="portfolio" class="Portfolios">
<return-property name="Name" column="name"/>
</return>
{ ? = call test_SP( :portfolioName) }
</sql-query>

</hibernate-mapping>




try {
Query query=q_session.getNamedQuery("test_SP");
query.setParameter("portfolioName","IDA");
List booking_ref=query.list();
} catch (Exception e) {
e.printStackTrace();
}

Name and version of the database you are using: SQL Server 2000

The generated SQL (show_sql=true): 15:40:49,163 INFO [STDOUT] Hibernate: { ? = call test_SP( ?) }

Debug level Hibernate log excerpt:
15:40:49,179 WARN [JDBCExceptionReporter] SQL Error: 0, SQLState: null
15:40:49,179 ERROR [JDBCExceptionReporter] Invalid Parameter index 0. JDBC indexes start at 1.

Well, finally found the examples under "test\org\hibernate\test\sql\" and modelled my trivial implemenation after the paramhandling example and got it working, at least enough to return a scalar. Now I just have to figure out how to get the mapping to happen a la: http://www.hibernate.org/hib_docs/v3/re ... /#sp_query

Suggestions welcomed.
