Oracle stored procedures, SYS_REFCURSOR and NHibernate

Question

I have a legacy Oracle (10.2g) database that I'm connecting to and I'd like to use NHibernate (2.0.1) to give me back objects from a stored procedure. The stored procedure in question uses a SYS_REFCURSOR to return results. According to the documentation this should be doable but I've found a few posts on the internet that suggest otherwise.

Here's my paraphrased code:

Mapping file:

<?xml version="1.0" encoding="utf-8" ?>
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" 
assembly="OracleStoredProcedures" namespace="OracleStoredProcedures">
    <class name="Person" mutable="false">
        <id name="PersonCode" type="AnsiString" column="PERSONCODE">
            <generator class="assigned" />
        </id>
        <property name="Name" type="String" column="PERSON_NAME" />
        <property name="Surname" type="String" column="PERSON_SURNAME" />
    </class>

    <sql-query name="getpeople">
        <return class="Person" />

        EXEC RS_DB.GETPERSONTEST 

    </sql-query>
</hibernate-mapping>

Stored procedure:

CREATE OR REPLACE PROCEDURE RS_DB.GETPERSONTEST (
   io_cursor   IN OUT   sys_refcursor
)
IS
BEGIN
   OPEN io_cursor FOR
      SELECT PERSONCODE, PERSON_NAME, PERSON_SURNAME
      FROM PEOPLE

END GETPERSONTEST;

Answer 1

What a royal pain this was. This finally worked. I turned the store procedure into a function. Function returned sys_refcursor. Used similar mapping as the OP and name query as below.

<sql-query name="getpeople">
 <return class="Person" />

 { ? = call RS_DB.GETPERSONTEST }
</sql-query>

As far as I remember this was a bug I also found a couple of years ago when working with oracle, I've tracked back the issue in NH tracker and is fixed but on version 2.1.1GA; Can you verify that this is the same problem you have? https://nhibernate.jira.com/browse/NH-847
