Full Join SQL Example
This example illustrates use of FULL JOIN action.
This query retrieves all event names and places where they happen. Venue is attached to event name if value of field "VenueNo" is equal in both tables. If there is no corresponding venue for event, then NULL is placed beside it. Likewise, if a corresponding event for a venue couldn"t be found, NULL is placed to the left of it.

select e1."Event_Name", v2."Venue"
from "events" e1 
full outer join "venues" v2
on (e1."VenueNo" = v2."VenueNo")
order by e1."Event_Name" asc, v2."Venue" asc

Testimonials

The other people in the office didn't believe me when I said that all I had to do was document the problem and you would probably give me a fix overnight. Unbelievable! Keep up the great work. I hope you guys all make a fortune out of this product because it is truly fantastic and the support is the best I have ever encountered.
