我正在尝试构建一个具有开始和结束日期的查询，并且此查询的结果为我提供了介于两者之间的日期和日期名称。然后我想JOIN到另一张预计支付日期和金额的表格。 JOINED表可能有更多天数在开始日期和结束日期之外，我想要排除这些日期。
我有我想要的东西，但没有正确的输出，到目前为止我创建了以下内容：
DECLARE
@startDate DATETIME,
@endDate DATETIME
SET @startDate = CONVERT(VARCHAR(4), DATEPART(YEAR, DATEADD(MONTH, -1, GETDATE())))+'-'+CONVERT(VARCHAR(2), DATEPART(MONTH, DATEADD(MONTH, -1, GETDATE())))+'-21'
SET @endDate = CONVERT(VARCHAR(4), DATEPART(YEAR, DATEADD(MONTH, -1, GETDATE())))+'-'+CONVERT(VARCHAR(2), DATEPART(MONTH, DATEADD(MONTH, -0, GETDATE())))+'-20'
;WITH dates AS
(
SELECT @startdate as Date,DATENAME(Dw,@startdate) As DayName
UNION ALL
SELECT DATEADD(d,1,[Date]),DATENAME(Dw,DATEADD(d,1,[Date])) as DayName
FROM dates
WHERE DATE < @enddate
)
SELECT LEFT(CONVERT(VARCHAR(30),Date, 106), 2) + '-' + LEFT(CONVERT(VARCHAR(30),Date, 10), 2) Date,DayName, SUM(ExpectedAmount), ExpectedDate FROM dates
FULL JOIN Commissions.dbo.ThreeMonthPayment on CONVERT(VARCHAR(30),Date) = Commissions.dbo.ThreeMonthPayment.ExpectedDate
GROUP BY Date, DayName, ExpectedDate
Order by ExpectedDate
这个表中的结果（抱歉这么久）：

在上述结果中，我尝试将ExpectedDate与date列匹配，因此我没有看到上述结果，而是看起来像这样:(保留它简而言之，我没有创建从开始和结束日期收到的所有日子）
+-------+-----------+------------------+--------------+
| Date | DayName | (No column name) | ExpectedDate |
+-------+-----------+------------------+--------------+
| NULL | NULL | 0 | NULL |
| 21-03 | Friday | 21074 | 21-03 |
| 22-03 | Saturday | 28401 | 22-03 |
| 23-03 | Sunday | 76562 | 23-03 |
| 24-03 | Monday | 47008 | 24-03 |
+-------+-----------+------------------+--------------+
但是您可以在上面看到expectedDate和date列已经很好地分组/连接在一起。并且不会显示不在expectedDates范围内的date。
整个上午我一直在努力:(这可能吗？
我可能错过的任何帮助或链接都很棒！
I am using SQL SERVER 2008
非常感谢。
答案 0 :(得分：1)
首先full join包含所有内容。从两个表。如果您只想要dates cte中的日期，请使用左连接。
其次，CONVERT(VARCHAR(30),Date) = Commissions.dbo.ThreeMonthPayment.ExpectedDate似乎不起作用。你确定需要转换吗？
我建议你试试这个：
DECLARE
@startDate DATETIME,
@endDate DATETIME
SET @startDate = CONVERT(VARCHAR(4), DATEPART(YEAR, DATEADD(MONTH, -1, GETDATE())))+'-'+CONVERT(VARCHAR(2), DATEPART(MONTH, DATEADD(MONTH, -1, GETDATE())))+'-21'
SET @endDate = CONVERT(VARCHAR(4), DATEPART(YEAR, DATEADD(MONTH, -1, GETDATE())))+'-'+CONVERT(VARCHAR(2), DATEPART(MONTH, DATEADD(MONTH, -0, GETDATE())))+'-20'
;WITH dates AS
(
SELECT @startdate as Date,DATENAME(Dw,@startdate) As DayName
UNION ALL
SELECT DATEADD(d,1,[Date]),DATENAME(Dw,DATEADD(d,1,[Date])) as DayName
FROM dates
WHERE DATE < @enddate
)
SELECT LEFT(CONVERT(VARCHAR(30),Date, 106), 2) + '-' + LEFT(CONVERT(VARCHAR(30),Date, 10), 2) Date
, DayName, SUM(ExpectedAmount), ExpectedDate
FROM dates
LEFT JOIN Commissions.dbo.ThreeMonthPayment
on Date = Commissions.dbo.ThreeMonthPayment.ExpectedDate
GROUP BY
Date
, DayName
, ExpectedDate
Order by
ExpectedDate
