I've tried using various formulas I could find for columns, but I haven't been successful. (Admittedly, my Excel skills aren't very sophisticated.)

问题 I am trying to calculate average monthly value of premiums for each POLICY_ID in monthly basis as shown below.

Note: Oracle version 12c What I've tried: SELECT T.*, SUM(PREMIUM) OVER(PARTITION BY T.POLICY_ID ORDER BY T.POLICY_ID, T.PAYMENT_DATE ROWS
