SQL & PL/SQL

Hi

I am trying to create procedure using reference cursor as out parameter. It is throwing following error..

PL/SQL: Compilation unit analysis terminated
PLS-00201: identifier 'SYS_REFCURSOR' must be declared


Procedure body is as follow

create procedure getdata(cur_data out sys_refcursor) is
begin
open cur_data for select * from emp;
end;

The problem occur in 8i , however it works fine in 9i.

let me know whether 8i doesn't support SYS_REFCURSOR or there is some other problem.

Thanks
Vishal
