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.
