SUBQUERY SELECT AS FIELD SQL Example
This sample demonstrates use of subquery representing a separate field.
For each entry in table "Venues" the query counts quantity of events from table "Events" and places this number in a column named "EventsCount".

select v1."Venue", 
(select count(*) from "Events" e1 where e1."VenueNo" = v1."VenueNo") as "EventsCount"
from "venues" v1
order by "EventsCount" desc

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.
