The following SQL statements evaluate the distribution of incoming messages over time and thus give an indication of the times of greatest utilization.

SELECT DATEPART(hour,EntryDate) AS OnHour,
       COUNT(*) AS Totals
FROM [eBiss3].[dbo].[Message]
GROUP BY DATEPART(hour,EntryDate)
       order by OnHour asc

SELECT CAST(EntryDate as date) AS ForDate,
       DATEPART(hour,EntryDate) AS OnHour,
       COUNT(*) AS Totals
FROM [eBiss3].[dbo].[Message]
GROUP BY CAST(EntryDate as date),
       DATEPART(hour,EntryDate)

DECLARE @TotalMessages INT;
SET @TotalMessages = select COUNT(*)from [eBiss3].[dbo].[Message];

SELECT 
       DATEPART(hour,EntryDate) AS OnHour,
       COUNT(*) AS Totals,
       CAST(round(COUNT(*) * 100.0 /@TotalMessages, 1) as decimal(5,1)) as Percentage,
       REPLICATE ( '*' , COUNT(*) * 100.0 /@TotalMessages) as BarGraph
FROM [eBiss3].[dbo].[Message]
GROUP BY 
       DATEPART(hour,EntryDate)
       order by OnHour asc
