some time yesterday trying to call an Oracle stored procedure(function) using the org.springframework.jdbc.object.StoredProcedure...When I tried to use the code above I kept getting an error like “invalid number or type of arguments”...Note that I had to use the OracleTypes.CURSOR, which I wasn’t sure would work....as an explicitly declared ref-cursor out parameter....There is no such restriction in SQL Server so the way we retreive the resultset using standard JDBC API
