[ http://issues.apache.org/jira/browse/DERBY-1319?page=all ]
Myrna van Lunteren updated DERBY-1319:
--------------------------------------
Summary: Need documentation on the toursdb demo database (was: Need
documentation on the toursdb schema.)
In fact, we need to document the entire toursdb database. I propose the name
'toursdb_readme.html', to be placed in the same place as the toursdb database
dir.

> Key: DERBY-1319

> Project: Derby
> Issue Type: Sub-task
> Components: Demos/Scripts
> Affects 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)
