Hi Group -
1) I have 3 tables: A, B and C
2) Each table has an unqiue associative field called cust_id
3) The cust_id HAS to be in table A, the cust_id *could* be in table
B, and the cust_id *could* be in table C
4) I need my query to: a) count all rows where cust_id is in table A but *not* in table B
AND *not* in table C b) display all emails where cust_id is in table A but *not* in table
B AND *not* in table C
Here's some of my queries of what I have:
This one is close I think:
select distinct A.email from A
left join A as ics on ics.custid = A.custid
left join B on B.custid = A.custid
left join C on C.custid = A.custid
where ics.custid <> A.custid;
THANK YOU!
