Hi folks,
here's a straight forward join that I simply can't get my head round.
I've got
consumables: cs_id, cs_make, cs_comments
cons_locations: cl_id, cl_desc
cons_stock: cs_id, cl_id, status (1=ordered, 2=in-stock)
(one stock record per stock item, qty=3 means 3 records)
I'm struggling to create a quiery to produce
cs_id, cs_make, cs_comments, cl_desc, hand_qty, order_qty
where hand_qty and order_qty is the number of records grouped by cs_id, cl_id,
and status.
I've done the simple part and created a view balances to tally the cons_stock
as:
create view balances as
select cost_cs_id, cost_cl_id, cost_css_id, count(*) as qty
from cons_stock
group by cost_cs_id, cost_cl_id, cost_css_id;
I then have trouble joining this to the consumables and locations table to get
the results I need.
