I am trying to load Entities from an Oracle Stored Procedure (not
function), as per NH-847 Stored Procedures with ref cursor out should
be supported. i am using v2.1.2, so this fix should be available.
However i am having problems in calling the stored procedure. as per
the documentation the first parameter of the procedure should be out
sys_refcursor and my procedure satisfies this condition. Below is a
simple example of the scenario:
Procedure:
CREATE OR REPLACE PROCEDURE GetAllUsers(
cp_users_out OUT sys_refcursor
)
AS
BEGIN
OPEN cp_users_out FOR
Select User_ID,User_name From Users;
END;
Mapping File:
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2"
namespace="NHibSample.Entities" assembly="NHibSample">
<class name="User">
<id name="Id" column="User_Id"/>
<property name="Name" column="User_Name"/>
</class>
<sql-query name="FetchUsers" callable="true">
<return alias="Users" class="User">
</return>
call astmGetAllUsers_prc()
</sql-query>
</hibernate-mapping>
Code:
var usersList = session.GetNamedQuery("FetchUsers").List();
Error Message:
ORA-06553: PLS-306: wrong number or types of arguments in call to
'ASTMGETALLUSERS_PRC'\n
There are some examples for functions but none for Oracle Stored
procedures, so even though the first parameter over here is sys ref
cursor, the documentation does not suggest whether the procedure
should include any paramaters. i tried doing but that failed, saying
the parameter value is not being set.
If anybody has tried out a Oracle Stored Procedure (not function)
could you please point me to a working example. I looked at Nhibernate
tests, and they are for functions.

Dinesh
