More not in issue

Hi,
I have three tables, one is the client information table (T1) contain an
uniqueid for the client, the other is client address table (T2), which
contains different type of address for the client (e.g. business address,
home address) and the different type of address is identified by addtype_c,
and it is link to T1 via clientid. The third table (T3) contains the media
request from the clients and the address (add_c) they want the media sent to
.
and of course, it has the fields clientid.
I need to generate the mailing lable for the client according to the address
that the client want the materials sent to. However, how can I create a
query to alert me that the address type that the clients want the materials
sent to is not in the address table.
Thanks in advance.One option change your business logic to require a ship-to address when the
client is filling in this information. Or add a WHERE clause to your query
to exclude NULL addresses or if you use a DEFAULT to exclude addresses = to
the DEFAULT.

Hi qjlee,
Since you didn't post DDL and sample data (www.aspfaq.com/5006), I'll
have to make some wild assumptions about your tables.
SELECT T3.ClientID, T3.add_c
FROM T3
WHERE NOT EXISTS
(SELECT *
FROM T2
WHERE T2.ClientID = T3.ClientID
AND T2.AddressType = T3.AddressType)
or
SELECT T3.ClientID, T3.add_c
FROM T3
LEFT JOIN T2
ON T2.ClientID = T3.ClientID
AND T2.AddressType = T3.AddressType
WHERE T2.ClientID IS NULL
Best, Hugo
