simple OUTER JOIN (I thought)
am 11.09.2007 16:38:36 von tescodiscolondon
Two tables:
Fruit
fruitID, fruitName
Basket
buyerID, fruitID
(ie. we can see which buyer has what fruit in their basket)
I simply want to display all available fruit and whether or not it's
in a specific persons' basket.
SELECT Fruit.fruitID, Fruit.fruitName, IsNull(buyerID, 0)
FROM Fruit INNER JOIN Basket ON Fruit.fruitID = Basket.fruitID
WHERE Basket.buyerID = 12
but this just gives me what's in buyer 12s' basket.
What am I doing wrong? Am I a basket case...

Ah yes, never put your criteria into a WHERE clause.
SELECT Fruit.fruitID, Fruit.fruitName, IsNull(buyerID, 0)
FROM Fruit INNER JOIN Basket ON Fruit.fruitID = Basket.fruitID AND
Basket.buyerID = 12
gives me what I wanted.
Forget this post.

^^^^^ OUTER, surely?
