Can someone help me with a query. I am lost as how to write this code.
I need to set the "Active" column to a value of Zero if it's DUP_PARAM value is equal to "2" and if there are duplicate values for the TransoporationValue within the same group of records with the same SSN.
Below is an example of what I am talking about. attached is the actual database table


Before Update :

SSN                       Active             DUP_PARAM       TransoporationValue

111119077            1                          2                      AirPlane
111119077            1                          0                      AirPlane
111119077            1                          3                      AirPlane
888990000              1                          3                          Train
222334000            1                          2                      Car
222334000            1                          13                    Car
222334000            1                          15                    Car
222334000            1                           2                      Truck

After Update :

SSN              Active             DUP_PARAM              TransoporationValue

111119077    0                             2                          AirPlane

111119077    1                             3                          AirPlane
888990000      1                             3                           Train
222334000    0                             2                           Car
222334000    1                             13                        Car
