SQL Server：兩個表連接顯示每天沒有數據的所有行

Question

我試圖創建一個報表查詢，顯示給定日期範圍，所有名稱，日期以及是否有數據。我非常接近，但是我對如何在數據中獲得這些最終的零值感到茫然。因此，這裏就是我想：

Name ID  Mth Day Count 
Auburn 7261 10 14 0 
Auburn 7261 10 15 0 
Auburn 7261 10 16 0 
Auburn 7261 10 17 0 
Auburn 7261 10 18 0 
Concord 7262 10 14 2 
Concord 7262 10 15 0 
Concord 7262 10 15 0 
Concord 7262 10 17 1 
Katey 7263 10 14 0 
Katey 7263 10 15 0 
Katey 7263 10 16 0 
Katey 7263 10 17 0 
Katey 7263 10 18 0 

相反，我得到：

Name ID  Mth Day Count 
Auburn 7261 10 14 0 
Auburn 7261 10 15 0 
Auburn 7261 10 16 0 
Auburn 7261 10 17 0 
Auburn 7261 10 18 0 
Concord 7262 10 14 2 
Concord 7262 10 17 1 
Katey 7263 10 14 0 
Katey 7263 10 15 0 
Katey 7263 10 16 0 
Katey 7263 10 17 0 
Katey 7263 10 18 0 

這裏是我的查詢：

SELECT PUE.Name as [Name], pue.EventID, 
MONTH(dates.Date) AS Month, DAY(dates.Date) AS Day, 
puc.idcount AS PicturesTaken 
from (
select name, eventid from Events where 
TourID = 444 and EventID > 7256 and EventID < 7323 
) PUE 
outer apply (
SELECT 
    Date = DateAdd(Day, n1.number * 10 + n0.number, '2014-10-14') 
FROM 
    (SELECT 1 AS number UNION SELECT 2 UNION SELECT 3 UNION SELECT 4 UNION SELECT 5 UNION SELECT 6 UNION SELECT 7 UNION SELECT 8 UNION SELECT 9 UNION SELECT 0) as n0 
CROSS JOIN 
    (SELECT 1 AS number UNION SELECT 2 UNION SELECT 3 UNION SELECT 4 UNION SELECT 5 UNION SELECT 6 UNION SELECT 7 UNION SELECT 8 UNION SELECT 9 UNION SELECT 0) as n1 
WHERE DateAdd(Day, n1.number * 10 + n0.number, '2014-10-14') BETWEEN '2014-10-14' AND '2014-10-18' 
) dates 
left outer join (
select eventid, convert(date,picturetakendate) as picdate, count(consumerdataid) as idcount from ConsumerData 
where EventID > 7256 and EventID < 7323 
group by eventid, convert(date,picturetakendate) 
) puc 
on pue.EventID = puc.EventID 
where puc.picdate = dates.Date or puc.idcount is NULL 
order by pue.eventid, MONTH(dates.Date), DAY(dates.Date) 

我明白爲什麼零點沒有顯示的名字了，這裏的外接表結果如下：

7262 2014-10-14 2 
7262 2014-10-17 1 
7265 2014-10-14 2 
7266 2014-10-14 2 

所以它在where子句中是非常有意義的，它不爲空或匹配日期。但是，如果我拿出where子句我爲每一個計數一排每日期即：

Concord 7262 10 14 2 
Concord 7262 10 14 1 
Concord 7262 10 15 1 
Concord 7262 10 15 2 
Concord 7262 10 16 2 
Concord 7262 10 16 1 
Concord 7262 10 17 1 
Concord 7262 10 17 2 
Concord 7262 10 18 2 
Concord 7262 10 18 1 

我這麼近，我知道那裏只是只是一些簡單的我失蹤，但每次嘗試我作出修復它實際上會使結果變得更糟，所以我在這裏尋求幫助。我想我只需要在外連接中修復查詢以某種方式顯示每個日期，如果我可以引用日期，則應用會更容易或更改其中的位置。但我一直無法弄清楚如何。

Answer 1

添加ISNULL條件的SELECT子句中

SELECT PUE.Name as [Name], pue.EventID, 
MONTH(dates.Date) AS Month, DAY(dates.Date) AS Day, 
ISNULL(puc.idcount,0) AS PicturesTaken 

轉換where子句ON

on pue.EventID = puc.EventID 
AND puc.picdate = dates.Date 

，而不是

where puc.picdate = dates.Date or puc.idcount is NULL
