Split single row into multiple rows containing time periods
Hi,
I have a table with rows like this:
id, intime, outtime
1, 2010-01-01 00:10, 2010-01-3 20:00
I would like to split this row into multiple rows, 1 for each 24hr period in the record.
i.e. The above should translate into:
id, starttime, endtime, period
1, 2010-01-01 00:10, 2010-01-02 00:10, 1
1, 2010-01-02 00:10, 2010-01-03 00:10, 2
1, 2010-01-03 00:10, 2010-01-03 20:00, 3
The first starttime should be the intime and the last endtime should be the outtime.
Is there a way to do this without hard-coding the 24hr periods?
Thanks,
Dan Scott
