Hello,
I'm trying to write a query and cannot figure out how to do it (or
whether it can be done in SQL alone). Given a table containing events
with their starting and ending days (may be single- or multi-day
events), I need a list of the events occurring each day:
CREATE TABLE test_events ( event_id serial, event_name text, start_time date, end_time date, CONSTRAINT event_pkey
PRIMARYKEY (event_id)
);
INSERT INTO test_events (event_name, start_time, end_time) VALUES
('First Event', '05/01/2006', '05/04/2006');
INSERT INTO test_events (event_name, start_time, end_time) VALUES
('Second Event', '05/02/2006', '05/02/2006');
INSERT INTO test_events (event_name, start_time, end_time) VALUES
('Third Event', '05/04/2006', '05/05/2006');
INSERT INTO test_events (event_name, start_time, end_time) VALUES
('Fourth Event', '05/07/2006', '05/07/2006');
The query results should look like:
5/1/2006 First Event
5/2/2006 First Event
5/2/2006 Second Event
5/3/2006 First Event
5/4/2006 First Event
5/4/2006 Third Event
5/5/2006 Third Event
5/7/2006 Fourth Event
I've been experimenting with set-returning functions, but I haven't
stumbled on the answer. Suggestions?
Thanks
