--The following will show records of all customers who haven't bought item
number 901.

SELECT * FROM Customers A
WHERE NOT EXISTS
(SELECT * FROM Link
WHERE CID = A.CID AND PID = 901)

I have three tables:

Products Table
PID
PName
PType

Linking Table
LID
PID
CID

Customers Table
CID
CName
CPhone

I am trying to make a single statement that will give me all the customers
that haven't bought a certain single product so i can make a list of people
to contact regarding that product.

Any help or suggestions would be greatly appreciated... I just can't seem to
get this one right.

SELECT c.CName, c.Cphone
FROM Customers c
LEFT OUTER JOIN
(Linking l
INNER JOIN Products p
ON l.pid = c.pid)
ON c.CID = l.CID
AND p.PName = 'some product name'
WHERE l.CID IS NULL

or
SELECT c.CName, c.Cphone
FROM Customers c
WHERE NOT EXISTS(
SELECT NULL
FROM Linking l
INNER JOIN Products p
ON l.pid = c.pid
WHERE c.CID = l.CID
AND p.PName = 'some product name')

I see you have got an answer.

But please next time, do not cross-post to every newsgroup you find. This is
not a Windows Server problem, nor a datamining or datawarehouse problem.
