CURSOR crs_validate IS
select * FROM <ACT_JUN_2006_LOB>;
this ACT_JUN_2006_LOB table name, I should able to pass it when I open the cursor ... any help appreciated. thanks.

Thanks all for the response. REFCURSOR does work: here is an example ... which I found on-line
procedure emp_test(
month varchar2,
year varchar2)
is
type cur_typ is ref cursor;
c cur_typ;
query_str varchar2(200);
emp_number number := 7900;
salary number;
name varchar2(30);
Begin
query_str := 'Select empno, ename, sal from emp_' || month ||'_'||year
|| ' where empno = :id';
open c for query_str using emp_number;
loop
fetch c into emp_number, name, salary;
exit when c%notfound;
dbms_output.put_line(emp_number);
end loop;
close c;
end;
