Retrieving Data from Child Table

Hi Experts,

I have the following 2 table structures:


Both locations are ints related to the following table


Now, my question is how can I get the date, pickup location id, pickup location name, dropoff id and dropoff name within 1 query?

Thank you

Assuming the pickup_location and dropoff_location are id's that tie into the Location table, you would query as follows:
        d.pickup_location, AS pickup_location_name,
        d.dropoff_location, AS dropoff_location_name
FROM    Deliveries d
LEFT JOIN Location t1 ON = d.pickup_location
LEFT JOIN Location t2 ON = d.dropoff_location

I used left joins just in case that location doesn't exist in the location table. If you know it always will, you can change the LEFT JOIN to INNER JOIN.
