Thank you.
One more question (hopefully, for your sake :), last one for today. Your code (below) works.
declare @QtyUse as Int;
set @QtyUse = 1;
update t1 set t1.qty_left = t1.qty_left - @QtyUse
from myTable t1
inner join
(select top (1) t2.pk from MyTable t2 where t2.rec_id = '1'
order by t2.date_rec) t2 on t1.pk = t2.pk
The only thing is, how do I determine that no record is found in the Select top(1) clause? So, that I can exit the While?
