Re: Sql help, for electronic meter reading

["Graham Kiff" <kiff@xxxxxxxxxxxxx>]

Hi Paul

I think this should do the trick:

SELECT datepart(hh,Date) AS HourOfDay, Sum(reading) AS Reading
FROM `electric`
where Date between '2005-03-29 00:00:00' and '2005-03-29 23:59:59'
group by datepart(hh,Date)

Cheers
Graham
