I have a table of callers and I want to be able to add a new column which shows the next time they called.
so I have columns
DateTime | Customer ID | Session ID |
I want to add a new column of "Called Back" which will look down for the next row that matches the Customer ID and then enter the Session ID so I can look up that call.
I'm struggling to find a solution for this, so any help would be great.
