Key: DERBY-1319
URL: http://issues.apache.org/jira/browse/DERBY-1319
Project: Derby
Type: Sub-task
Components: Demos/Scripts
Versions: 10.2.0.0
Reporter: Stan Bradbury
Priority: Minor
Docuement the toursdb schema and provide examplet queries so toursdb can be
used by newbie Derby users. To jump start this here is a query that
demonstrates how to join the tables in the schema to list the with seats
available on a given day from one city to another. It's not pretty - a good
candidate for a view. (sans the hardcoded values listed below:
This example hardcodes the following string values:
Travel Date: '2004-04-12' , Departing city: Copenhagen , Destination
city: Paris
select f.flight_id, a.airline_full,
fa.flight_date|| ' ' || f.depart_time Departing,
CAST(orig_city.city_name ||', ' || orig_ctry.country as varchar(30)) as
Origin,
f.flying_time Hours, f.arrive_time Arriving,
CAST(dest_city.city_name ||', ' || dest_ctry.country as varchar(30)) as
Destination
from flights f, airlines a, countries orig_ctry, cities orig_city,
countries dest_ctry, cities dest_city, flightavailability fa
where f.flight_id = fa.flight_id and f.segment_number = fa.segment_number
and orig_city.airport = f.orig_airport and dest_city.airport = f.dest_airport
and orig_city.country_iso_code = orig_ctry.country_iso_code
and dest_city.country_iso_code = dest_ctry.country_iso_code
and f.flight_id like a.airline || '%'
and fa.flight_date = '2004-04-12'
and (a.business_seats - fa.business_seats_taken) > 0
and orig_city.city_name = 'Copenhagen' and dest_city.city_name = 'Paris'
order by f.flight_id, f.segment_number
NOTE: uses some kludgy formatting tricks
To cut N paste the query all at once into IJ set maximumdisplaywidth larger
(about 985 characters in the query)
