Hi, I have two tables CustomerAddress(CustomerId, City, Country) and CustomerTransactions(TransactionId, CustomerId, CustomerContact). Here are the values in the tables:
For CustomerAddress:
1001, El Paso, USA
1002, Paris, France
1003, Essen, Germany
For CustomerTransactions:
98, 1001, Phillip
99, 1001, NULL
100, 1001, NULL
101, 1003, Carmen
102, 1003, Carmen
103, 1003, Lola
104, 1003, NULL
105, 1002, NULL
I'm trying to join both tables and have the following result set:
1001, El Paso, USA, Phillip
1002, Paris, France, (empty string)
1003, Essen, Germany, Carmen
1003, Essen, Germany, Lola
It seems like a simple join but I'm having trouble coming up with the above result set. Please help.
Thanks.
