VC 7.0 Oracle stored procedures resultset with ref cursor

Can VC (we are on NW7 SP13) handle Oracle's datatype ref cursor - which is the standard solution in Oracle to return result sets - as the return value of a stored procedure?

When testing a data service in the VC story board based upon a simple Oracle function like:

create or replace package pkg_dev


type t_cursor is ref cursor;


create or replace function vc_stub return pkg_dev.t_cursor


l_cursor pkg_dev.t_cursor;


open l_cursor for select ename from emp;

return l_cursor;


(just as example - I know that could be easily retrieved using the BI JDBC connector framework and accessing tables / views)

I am always running in the "portal request failed ( Could not execute Stored Procedure)" error - so I am not able to use the "add fields" function to bind the output.

The defaulttrace contains entries like:



com.sapportals.connector.execution.ExecutionException: Could not execute stored procedure


Caused by: java.sql.SQLException: Invalid column type

at oracle.jdbc.driver.DatabaseError.throwSqlException(

We deployed Oracle's own jdbc-driver for Oracle 10g. Using that driver and a portal jdbc connector framework entry the stored procedures of the Oracle database user mapped to the portal user are discovered and available in the "Find Data Services" section.
