在IndexedDB中查找重叠的日期范围

Question

I would like to find which date ranges overlaps a period in IndexedDB.

My idea was to store my events in a database, then make a query to get the events which overlap the period range.

Something like the following query (sorry, I don't really remember how to write SQL):

SELECT * FROM events
WHERE (startTime BETWEEN periodStart AND periodEnd)
OR 
(periodStart > startDate AND periodStart < endTime)

Unfortunately, the only possibility that I found with IndexedDB is to test if a date overlap a range.

For your informations, my events look like the following object:

[{
  title: 'foo',
  start: '2013-06-30',
  end: '2013-07-03'
},
{
  title: 'bar',
  start: '2013-07-04',
  end: '2013-07-11'
}]

And a period is like:

var periodStart = '2013-06-30';
var periodEnd = '2013-07-05';

为什么不只使用时间戳的数值？
