Or...
SELECT
Shop,
Product,
CASE WHEN sp.fkProduct IS NULL THEN 'no' ELSE 'yes' END AS
'Available'
FROM Shop, Product
LEFT OUTER JOIN ShopProduct AS sp ON ( Product.pk = sp.fkProduct ) ORDER
BY Shop
I've never seen a problem that was solved with a cartesian join before,
interesting :O)

Get rid of the hashs and change the names to your table names Justin and it
should work.

I havent had a chance to look at it, and this will work, but you shouldn't
need to use a temporary table for this......will have a look post-work and
see what I can come up with.!

This seems to work on SQL Server....
CREATE TABLE #product ( pk int, product varchar(50) ) CREATE TABLE #shop (
pk int, shop varchar(50) ) CREATE TABLE #shopProduct ( fkProduct int, fkShop
int )
INSERT INTO #product ( pk, product ) VALUES ( 1, 'pro_1' ) INSERT INTO
#product ( pk, product ) VALUES ( 2, 'pro_2' ) INSERT INTO #product ( pk,
product ) VALUES ( 3, 'pro_3' ) INSERT INTO #product ( pk, product ) VALUES
( 4, 'pro_4' )
INSERT INTO #shop ( pk, shop ) VALUES ( 1, 'shop_1' ) INSERT INTO #shop (
pk, shop ) VALUES ( 2, 'shop_2' ) INSERT INTO #shop ( pk, shop ) VALUES ( 3,
'shop_3' )
INSERT INTO #shopProduct ( fkProduct, fkShop ) VALUES ( 1, 1 ) INSERT INTO
#shopProduct ( fkProduct, fkShop ) VALUES ( 1, 2 ) INSERT INTO #shopProduct
( fkProduct, fkShop ) VALUES ( 2, 1 ) INSERT INTO #shopProduct ( fkProduct,
fkShop ) VALUES ( 3, 2 )
SELECT
Shop,
Product,
CASE WHEN sp.fkProduct IS NULL THEN 'no' ELSE 'yes' END AS
'Available'
FROM #shop, #product
LEFT OUTER JOIN #shopProduct AS sp ON ( #product.pk = sp.fkProduct ) ORDER
BY Shop
It looks right to me, but you'll know for sure if it's doing what you need.

Where is the availability flag? Is it simply if it exists in a shop?

My brain is still in xmas mode, and what should be simple sql is a
challange!
I want to do a query, that lists all the products , with a column with a
yes/no (boolean/bit) column to say if the product is available in that shop
or not
so with
[Product]
pk product
------------------
1 product1
2 product2
3 product3
[Shop]
pk shop
--------------
1 shop_1
2 shop_2
[ShopProduct]
FKProduct FKShop
-------------------
1 1
1 2
2 1
3 2
I should have
Shop product available
------------------------------
shop_1 product1 yes
shop_1 product2 yes
shop_1 product3 no
shop_2 product1 yes
shop_2 product2 no
shop_2 product3 yes
I know its a CROSS JOIN between shop and product with a outer? join on the
ShopProduct table but just can't get it together...
Thanks
Justin
