Sql 逐小时报表的查询数据

我的任务是写一份报告，它会显示一个条形图，其中X轴是班次的小时数，所以底部是1-8。条形图是每小时完成的事务数。所以柱状图很容易让你看到，在第一个小时我们处理了30份订单，第二个小时我们处理了25份，以此类推，直到轮班结束

不过，我很难弄清楚如何实际创建此报告。这是我做类似事情的唯一选择。请理解这只是伪代码，不要费心评论语法问题：

create table #temp
(
  Hour int,
  Units int
)

insert into #temp
SELECT 1 as Hour, sum(Units) Units
FROM orders
WHERE DateCreated >= '6/14/2013 08:00:00' AND DateCreated < '6/14/2013 09:00:00'

insert into #temp
SELECT 2 as Hour, sum(Units) Units
FROM orders
WHERE DateCreated >= '6/14/2013 09:00:00' AND DateCreated < '6/14/2013 10:00:00'

insert into #temp
SELECT 3 as Hour, sum(Units) Units
FROM orders
WHERE DateCreated >= '6/14/2013 11:00:00' AND DateCreated < '6/14/2013 12:00:00'

.. and so on ..

select * from #temp

此外，它位于报表调用的存储过程中

有更好的方法吗？我是否应该将一整天的数据发送到报告中，并在报告中进行处理？任何见解都将不胜感激。

+1这为我提供了一种更好的获取所需数据的方法。我现在正在修补它，如果这最终解决了我的问题，我会把它标记为答案。非常感谢。

SELECT DATEPART(hh, DateCreated) AS hour, sum(Units) Units
FROM orders
WHERE DateCreated >= '6/14/2013' AND DateCreated < '6/15/2013'
GROUP BY DATEPART(hh, DateCreated)

SELECT DATEPART(dd, DateCreated) AS day, DATEPART(hh, DateCreated) AS hour, sum(Units) Units
FROM orders
WHERE DateCreated >= '6/10/2013' AND DateCreated < '6/15/2013'
GROUP BY DATEPART(dd, DateCreated), DATEPART(hour, DateCreated)
