Hi folks.
I've got a database for my consumable stock. I have a consumables table
containing the type details, e.g. HP 4100 toner.
I then have a cons_stock table holding item details, one record per item (2
toners = 2 rows).
I have a order_dets view which pulls in all the data required including order
details (order number, state, supplier etc.), location description, supplier
details etc.
This works fine. I now want a variation of this, but instead of showing
individual items I want to show only consumable types and a quantity.
Below are the two views, along with example output. Can anyone see where I've
gone wrong?
create view order_dets as select c.cs_id, c.cs_make, c.cs_code, c.cs_type, cst.cst_desc, c.cs_colour,
cs.cost_id,cs.cost_cl_id, cs.cost_supp, o.or_id, o.or_supp, o.or_date, o.or_received, o.or_no, orst.orst_desc as
order_state, co.co_id, co.co_name, co.co_person, co.co_tel, co.co_mobile, co.co_fax, co.co_email, co.co_type,
cl.cl_desc, c.cs_comments, cs.cost_comments from consumables c, orders o, cons_stock cs, contacts co,
cons_locationscl, cons_types cst, order_states orst where cs.cost_cs_id = c.cs_id and cs.cost_or_id = o.or_id
and c.cs_type = cst.cst_id and o.or_supp = co.co_id and o.or_state = orst.orst_id and cs.cost_cl_id =
cl.cl_id;
create view order_summary as select c.cs_id, cs.count as qty, c.cs_make, c.cs_code, c.cs_type, cst.cst_desc,
c.cs_colour, o.or_id, o.or_supp, o.or_date, o.or_received, o.or_no, orst.orst_desc as
order_state, co.co_id, co.co_name, co.co_person, co.co_tel, co.co_mobile, co.co_fax, co.co_email, co.co_type,
c.cs_comments from consumables c, orders o, (select cost_cs_id, cost_or_id, count(cost_cs_id) from
cons_stock where cost_or_id is not null group by cost_cs_id, cost_or_id ) cs, contacts co,
cons_locations cl, cons_types cst, order_states orst where cs.cost_cs_id = c.cs_id and cs.cost_or_id = o.or_id
and c.cs_type = cst.cst_id and o.or_supp = co.co_id and o.or_state = orst.orst_id;
