"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.
can't test, but try this :
SELECT count(0) as nMessages, convert(nvarchar, datetimein, 103) as currDate, RIGHT(CONVERT(VARCHAR,datetimein, 100),7) as currHour
FROM [radiomix].[dbo].[chat]
GROUP BY convert(nvarchar, datetimein, 103), RIGHT(CONVERT(VARCHAR,datetimein, 100),7)
If you are wanting to see the hours across the report, try this:
SELECT reqport,
SUM(CASE WHEN DATEPART(hh, datetimein) = 0 THEN 1 ELSE 0 END) AS 'Midnight',
SUM(CASE WHEN DATEPART(hh, datetimein) = 1 THEN 1 ELSE 0 END) AS '1:00 AM',
SUM(CASE WHEN DATEPART(hh, datetimein) = 2 THEN 1 ELSE 0 END) AS '2:00 AM',
-- additional times here
SUM(CASE WHEN DATEPART(hh, datetimein) = 23 THEN 1 ELSE 0 END) AS '11:00 PM'
FROM radiomix.dbo.chat
GROUP BY reqport,
YEAR(datetimein),
MONTH(datetimein),
DAY(datetimein)
The above won't give you the date. Use
SELECT reqport,
CAST(datetimein AS DATE) AS Date,
SUM(CASE WHEN DATEPART(hh, datetimein) = 0 THEN 1 ELSE 0 END) AS 'Midnight',
SUM(CASE WHEN DATEPART(hh, datetimein) = 1 THEN 1 ELSE 0 END) AS '1:00 AM',
SUM(CASE WHEN DATEPART(hh, datetimein) = 2 THEN 1 ELSE 0 END) AS '2:00 AM',
-- additional times here
SUM(CASE WHEN DATEPART(hh, datetimein) = 23 THEN 1 ELSE 0 END) AS '11:00 PM'
FROM dbo.chat
GROUP BY reqport,
CAST(datetimein AS DATE)

WHEN DATEPART(hh, datetimein) BETWEEN 1 AND 11 THEN DATENAME(HH, datetimein) + ':00 AM'
