Hi guys,
I need a function that will return No. of Days and No. of Nights in a given period of Date and Time.
e.g. 28/11/2012 01:00 and 30/11/2012 12:00
Consider below
From 00:00 to 06:00 should be considered as DAY and From 06:01 to 23:59 should be considered as NIGHT...
Plz reply...

Something like this:

SELECT DATEDIFF(dd,@startDate, @endDate)
	+ CASE WHEN CAST(@startDate AS TIME ) > '06:00' THEN -1 ELSE 0 END AS [Days],
	DATEDIFF(dd,@startDate, @endDate) 
	+ CASE WHEN CAST(@endDate AS TIME ) <= '06:00' THEN -1 ELSE 0 END AS [Nights]
