Get last previous value of a record if condition is true
I have the following table:
+ ---------+------------+--------------+-------------+-------------+----------------+
| RecordId | Client | Subscription | Status | Date | Payment Method |
+ ---------+------------+--------------+-------------+-------------+----------------+
| ABC1234 | John Doe | NetFlex | Renewed | 13 Nov 2018 | Credit Card |
| ABC1233 | Jane Smith | SplitiFy | Not Renewed | 01 Sep 2018 | NULL |
| ABC1232 | John Doe | NetFlex | Renewed | 13 Nov 2017 | PayPart |
| ABC1231 | Jane Smith | SplitiFy | Renewed | 01 Sep 2017 | Cash |
| ABC1230 | John Doe | NetFlex | Renewed | 13 Nov 2016 | Cash |
+ ---------+------------+--------------+-------------+-------------+----------------+
I would like to have a new column in which I can provide the previous payment method for a specific client, and setting it to NULL if there was not a previous payment. In other words, I would like to have the following information
+ ---------+------------+--------------+-------------+-------------+----------------+-------------------------+
| RecordId | Client | Subscription | Status | Date | Payment Method | Previous Payment Method |
+ ---------+------------+--------------+-------------+-------------+----------------+-------------------------+
| ABC1234 | John Doe | NetFlex | Renewed | 13 Nov 2018 | Credit Card | PayPart |
| ABC1233 | Jane Smith | SplitiFy | Not Renewed | 01 Sep 2018 | None | Cash |
| ABC1232 | John Doe | NetFlex | Renewed | 13 Nov 2017 | PayPart | Cash |
| ABC1231 | Jane Smith | SplitiFy | Renewed | 01 Sep 2017 | Cash | NULL |
| ABC1230 | John Doe | NetFlex | Renewed | 13 Nov 2016 | Cash | NULL |
+ ---------+------------+--------------+-------------+-------------+----------------+-------------------------+

If you are using SQL Server 2012 or higher then you can make use of LAG which will return data from a previous row in the same result set without the use of a self-join
So here we can use LAG In combination with PARTITION BY to get the Expected Result
SELECT RecordId,Client,Subscription,Status,Date,PaymentMethod
,LAG (PaymentMethod, 1, 0) OVER (PARTITION BY Client,Subscription ORDER BY Date)
AS PreviousPaymentMethod
FROM Table
