I have a calendar with events: Calendar always have a start point and end point ( example 29.04.2014 till 09.6.2014)
Events are shown from this date range:
AND DATE(event_from) >= DATE(?) //29.04.2014
AND DATE(event_to) <= DATE(?) //09.6.2014
But if event starts 28.04 and ends 10.6.2014 it want shown in calendar
How can I show this event if it exceeds the range, but also remains in range
Thanks to klin:
All together
AND (daterange(DATE(event_from), DATE(event_to)) && daterange(DATE(?), DATE(?)) OR( DATE(event_from) >= DATE(?) AND DATE(event_to) <= DATE(?) ) )
Use the type daterange
and overlap operator :
with ranges(event_from, event_to) as (
values
('2016-04-01'::date, '2016-06-01'::date),
('2016-01-01', '2016-03-01'),
('2016-05-01', '2016-05-15')
)
select *
from ranges
where daterange(event_from, event_to) && daterange('2016-05-01', '2016-05-31');
event_from | event_to
