This example illustrates how to get data from two tables using EQUI-JOIN.
The query lists all events and venues where they take place. Notice that only those entries will be shown that have corresponding values in both tables. If event name has empty field "VenueNo" or its value is never met in same field of table "Venues", then this event will not be included in the resulting dataset.
select e1."Event_Name", v2."Venue"
from "events" e1, "venues" v2
where (e1."VenueNo" = v2."VenueNo")
orderby e1."Event_Name" asc, v2."Venue" asc
