Very Good Article. I have a question. Suppose you have a dimension that contains certain columns that are type 2 where you want to keep track of historical changes. However, the dimension also contains type 1 columns where you just want to overwite existing values without creating a new record with a different surrogate key.

For example, I have a customer record that contains an address field. If the address changes, I want to handle it as a type 2 change. However, the record also contains a phone number which I just want updated in place when it changes but does not require the creation of a new record with a different surrogate key.

Can you handle this scenario within the same merge statement?
