Question

I have a SQL Server 2008 database with a table that has a column (datetime datatype) recording when an order is placed.

I would like to run a query that will give a breakdown of total amount of orders per hour on any given date or date range but am unsure of the best way to write the query.

Answer 1

It should be something along the lines of:

SELECT DATEPART(HOUR, OrderDate) AS [Hour], COUNT(*) AS [Count]
FROM [Orders]
WHERE OrderDate BETWEEN @StartDate AND @EndDate --or whatever criteria
GROUP BY DATEPART(HOUR, OrderDate)
