Hi,
I'm looking for a query to find the first dates and last dates in a table conaining overlapping dates.
I have a subscription table which has for each Customer start and end date for different subscriptions.
I want to know the different ranges of date where there is subscriptions active.
so if the table has this:
CustID, Start date, end date
1, 2008-01-01, 2012-06-06
1 ,2009-01-01, 2011-01-01
1, 2011-01-01, 2013-02-02
1, 2013-01-01, 2013-08-08
1, 2014-01-01, 2014-04-04
I want to produce this result:
custid, range start, range end
1, 2008-01-01, 2013-08-08
1, 2014-01-01, 2014-04-04
the first row is the range identified from the 4 rows in my subscription table.
thanks :)
