Perform a loop in SQL

Question

Hello I am trying to test one of my PL/SQL procedures by trying to write one single query that should do exactly what the procedure does. The problem is the procedure contains a loop in it that looks like so:
For i in 1..10
loop
LS := LS + 1;
end loop;
does anyone know how i can replicate this loop in a query.
I came the the solution of just writing 10 levels of query. Where the inside query would calculate LS, the outer would calculate LS + 1 and so on and so forth. But this method is quite slow. Any other ideas????
Thanks ahead of time!

I am trying to test one of my PL/SQL procedures by trying to write one single query that should do exactly what the procedure doesForgive me, but that seems to be a bizarre way of tackling things. Apart from anything else, we should only be using PL/SQL for stuff we cannot do in SQL. So if you could write the query maybe you don't need the procedure...
Anyway, a better test would be to make an assertion about what the PL/SQL actually does and exercise the code. For instance, let's say you're inserting a record with LS as the primary key.
DECLARE
   dummy varchar2(10);
BEGIN
   call_your_proc;
   SELECT null INTO dummy
   FROM   some_table
   WHERE  pk = 10;
EXCEPTION
   WHEN no_data_found THEN
      RAISE_APPLICATION_ERROR(-20000, 'The test failed!');
END;
