如何按小時日期時間範圍計算唯一列值？

Question

我有一個查詢，我一直在努力，不能拼湊在一起的最後一部分。我希望以下查詢根據給定的StartTime範圍每小時返回一個總計數[Meta_ID]列，並且總計僅在該小時內計數[Meta_ID]，且沒有任何愚蠢行爲。在此先感謝您的任何建議！

SELECT [Detail_ID] 
,[Meta_ID] as PlayerID 
,p.FirstName 
,p.LastName 
,u.FirstName as Host 
,[StartTime] 
,CAST(StartTime as date) AS ForDate, 
     DATEPART(hour,StartTime) AS OnHour, 
     COUNT(*) AS Totals 
FROM [SDIDW].[dbo].[CDS_StatDetail] (nolock) 
join CDS_Player p on p.Player_ID = Meta_ID 
join CDS_User u on u.User_ID = p.HostUser_ID 
--join dbo.PlayerDAP d on d.PlayerId = Meta_ID 
WHERE StartTime >= '2017-06-04 00:00:00.000' 
AND StartTime <= '2017-06-10 23:59:59.999' 
AND StatType like '%SLOT%' 
AND Meta_ID in (
10, 
111, 
112, 
126, 
127, 
147, 
155, 
189, 
234, 
237, 
271, 
273, 
287, 
321, 
404) 
GROUP BY CAST(StartTime as date), 
     DATEPART(hour,StartTime), 
[Detail_ID] 
,[Meta_ID] 
,p.FirstName 
,p.LastName 
,u.FirstName 
,[StartTime] 

這是目前我所得到的。我已經刪除了這張表中的名字。

+-----------+----------+-----------------+----------+--------+--------+ 
| Detail_ID | PlayerID | StartTime | ForDate | OnHour | Totals | 
+-----------+----------+-----------------+----------+--------+--------+ 
| 209381040 |  1115 | 6/4/17 12:08 AM | 6/4/2017 |  0 |  1 | 
| 209381317 |  1115 | 6/4/17 12:15 AM | 6/4/2017 |  0 |  1 | 
| 209381453 |  492 | 6/4/17 12:10 AM | 6/4/2017 |  0 |  1 | 
| 209381800 |  1891 | 6/4/17 12:36 AM | 6/4/2017 |  0 |  1 | 
| 209381805 |  1200 | 6/4/17 12:37 AM | 6/4/2017 |  0 |  1 | 
| 209382181 |  1200 | 6/4/17 12:48 AM | 6/4/2017 |  0 |  1 | 
| 209382753 |  1069 | 6/4/17 12:13 AM | 6/4/2017 |  0 |  1 | 
| 209382581 |  1200 | 6/4/17 1:02 AM | 6/4/2017 |  1 |  1 | 
| 209383570 |  1069 | 6/4/17 1:10 AM | 6/4/2017 |  1 |  1 | 
| 209383752 |  1069 | 6/4/17 1:47 AM | 6/4/2017 |  1 |  1 | 
| 209386313 |  126 | 6/4/17 5:10 AM | 6/4/2017 |  5 |  1 | 
| 209386352 |  126 | 6/4/17 5:22 AM | 6/4/2017 |  5 |  1 | 
+-----------+----------+-----------------+----------+--------+--------+ 

但是我想得到的是更多沿右邊添加列的行，如下所示。我試圖每小時獲得一次Meta_ID的唯一計數。

+-----------+----------+-----------------+----------+--------+--------+------+--------+

+-----------+----------+-----------------+----------+--------+--------+------+--------+

| 209381317 |  1115 | 6/4/17 12:15 AM | 6/4/2017 |  0 |  1 | 1 |  2 | 
| 209381453 |  492 | 6/4/17 12:10 AM | 6/4/2017 |  0 |  1 | 5 |  1 |
