‘start_date’ which is the ORDER_DATE (day the order was placed), the second argument is ‘end_date’, which is the SHIP_DATE (date the order was shipped). So by subtracting as follows: SHIP_DATE – ORDER_DATE, we can find the delay in shipping.
Click OK.

For example, consider the following two tables originating from a single data source:
