procedure.

declare @inv_id integer,
@sales_rep_id integer

declare cursor1 cursor for
select inv_id,sales_rep_id
from invoice

open cursor1

fetch cursor1 into @inv_id,@sales_rep_id

while (@@sqlstatus=0)
begin

update employee
set commiss_tot = commiss_tot + 15
where emp_id = @sales_rep_id

fetch cursor1 into @inv_id,@sales_rep_id
end
