help with cost query

Hi,

 

I have a table that contains the stores, and the number of an item it sold.

store     apple    orange blueberry           pineapple            peach

s1            0              10           3              6              1

s2            6              8              4              3              4

s3            4              3              20           0              48

s4            9              0              45           35           1

s5            4              3              0              8              4

 

I have another table, that has the cost of each of these items

apple     25

orange  21

blueberry            18

pineapple            10

peach    15

 

I need a query that will provide me the cost per store for each item based on the cost table e.g.

store     apple    orange blueberry           pineapple            peach

s1            0              210         54           60           15

s2            150         168         72           30           60

s3            100         63           360         0              720

s4            225         0              810         350         15

s5            100         63           0              80           60

 

If possible I would also like a "total" column at the end of this query that sums up the cost.

 

Any idea how to go about doing this?  Thanks

Freely admit I'm not strong with Access, but understand it doesn't have an 'unpivot'. Here the data is in presented in a 'pivoted' (non-normalized) fashion which as seen above will require multiple joins (one per column in effect).

I'm tempted to propose something like the following, which you could then "cross tab" to pivot for presentation.
select
  store
, item
, qty
, qty * rate
from ((
        select store, apple as qty     , 'apple' as item    where apple > 0
        union all
        select store, orange as qty   , 'orange' as item    where orange > 0
        union all
        select store, blueberry as qty, 'blueberry' as item where blueberry > 0
        union all
        select store, pineapple as qty, 'pineapple' as item where pineapple > 0
        union all
        select store, peach as qty    , 'peach' as item     where peach > 0
     ) s
inner join rates on s.item = rates.item)

nb: the quantity of brackets required is a best guess, access seems to need more than most products.

Try something like this.

SELECT (apple.Itemtablename*applerate.ratetablename),(orange.Itemtablename*orangerate.ratetablename),(blueberry.Itemtablename*blueberryrate.ratetablename),(pineapple.Itemtablename*pineapplerate.ratetablename),(peach.Itemtablename*peachrate.ratetablename)
FROM iteams
INNER JOIN Rates
ON uniquefiled.Iteams=uniquefiled.Rates
ORDER BY Store.Itemstablename;

I really don't know how to go about doing this.  but this is what i did below

SELECT storeName, appleCount * Apple.cost as appleSubtotal, orangeCount * Orange.cost as orangeSubtotal, blueberryCount * Blueberry.cost as blueberrySubtotal
FROM storeData,
(SELECT * FROM costSchedule WHERE item = 'Apple') as Apple,
(SELECT * FROM costSchedule WHERE item = 'Orange') as Orange,
(SELECT * FROM costSchedule WHERE item = 'Blueberry') as Blueberry

netballi,

In your query do I need additional tables?

I will call the firsttable as itemtable and the second table as costtable. Since there is no relation between the tables, here is what I think a way to do it:
select i.store
	 , i.apple * c1.cost as applecost
	 , i.orange * c2.cost as orangecost
	 , i.blueberry * c3.cost as blueberrycost
	 , i.pinapple * c4.cost as pinapplecost
	 , i.peach * c5.cost as peachcost
	 , (i.apple * c1.cost + i.orange * c2.cost + i.blueberry * c3.cost + i.pinapple * c4.cost + i.peach * c5.cost) as totalcost
  from itemtable i
  JOIN costtable c1 ON c1.item='apple'
  JOIN costtable c2 ON c1.item='orange'
  JOIN costtable c3 ON c1.item='blueberry'
  JOIN costtable c4 ON c1.item='pinapple'
  JOIN costtable c5 ON c1.item='peach'
