प्रति घंटे दिनांक समय की गणना द्वारा SQL सर्वर समूह?

इस बारे में कैसा है? SQL सर्वर 2008 मानते हुए:

SELECT CAST(StartDate as date) AS ForDate,
       DATEPART(hour,StartDate) AS OnHour,
       COUNT(*) AS Totals
FROM #Events
GROUP BY CAST(StartDate as date),
       DATEPART(hour,StartDate)

2008 से पहले के लिए:

SELECT DATEADD(day,datediff(day,0,StartDate),0)   AS ForDate,
       DATEPART(hour,StartDate) AS OnHour,
       COUNT(*) AS Totals
FROM #Events
GROUP BY CAST(StartDate as date),
       DATEPART(hour,StartDate)

इसका परिणाम है:

ForDate                 | OnHour | Totals
