Say I have a startdate = '2010/04/01'
and an enddate = '2011/02/01'
.
How would I set up a query such that I retrieve the following table as a response:
month
2010/04/01
2010/05/01
2010/06/01
2010/07/01
2010/08/01
2010/09/01
2010/10/01
2010/11/01
2010/12/01
2011/01/01
2011/02/01
Note that I'm not too fussed about the format, anything that works will do.
PostgreSQL有generate_series()
使这项任务变得简单:
SELECT generate_series('2010-04-01', '2011-02-01', interval '1 month')::date
