如何在 SQL 服务器中加入两个动态数据透视表（table 数据透视表后的数据）

Question

说明

我有一个 table 并且我对它们的 table 进行了透视，以便只获得 1 table 的所有数据。我附上了一张图片，其中包含我拥有的 table 和我想要得到的结果。

Table:

使用下面的查询进行动态数据透视后，我们将根据需要获得记录，但分为两个 table

DECLARE @cols nvarchar(max)
DECLARE @cols1 nvarchar(max)

DECLARE @stmt nvarchar(max)
DECLARE @stmt1 nvarchar(max)

SELECT @cols = STRING_AGG(QUOTENAME([YearMonth]), ',') WITHIN GROUP (ORDER BY [YearMonth])
FROM (
SELECT REPLACE(RIGHT(CONVERT(VARCHAR(9), CreatedOn, 6), 6), ' ', '/') AS [YearMonth]
FROM [dbo].[TblDemoData]
UNION
SELECT NULL
WHERE 1 = 0
) t
SELECT @cols1 = STRING_AGG(QUOTENAME([YearMonth1]), ',') WITHIN GROUP (ORDER BY [YearMonth1])
FROM (
SELECT REPLACE(RIGHT(CONVERT(VARCHAR(9), CreatedOn, 6), 6), ' ', '_') AS [YearMonth1]
FROM [dbo].[TblDemoData]
UNION
SELECT NULL
WHERE 1 = 0
) t1

print @cols1


SELECT * INTO #Data
FROM
(
select AgentId,
case
when sum( MaximumScore)=0
then 0
else
sum(ISNULL(AchievedScore,0)*100)/sum(ISNULL(MaximumScore,0))
end as Score,
COUNT(T.Id) as NumberOfAudit,
REPLACE(RIGHT(CONVERT(VARCHAR(9), T.CreatedOn, 6), 6), ' ', '/') AS [YearMonth]
from [dbo].[TblDemoData] T
where T.AgentId=49
group by AgentId,REPLACE(RIGHT(CONVERT(VARCHAR(9), T.CreatedOn, 6), 6), ' ', '/')
)TAB



SELECT * INTO #Data1
FROM
(
select T.AgentId,
case
when sum( MaximumScore)=0
then 0
else
sum(ISNULL(AchievedScore,0)*100)/sum(ISNULL(MaximumScore,0))
end as Score,
COUNT(T.Id) as NumberOfAudit,
REPLACE(RIGHT(CONVERT(VARCHAR(9), T.CreatedOn, 6), 6), ' ', '_') AS [YearMonth1]
from [dbo].[TblDemoData] T

where T.AgentId=49
group by T.AgentId,REPLACE(RIGHT(CONVERT(VARCHAR(9), T.CreatedOn, 6), 6), ' ', '_')
)TAB
SELECT @stmt =
'SELECT * from
(
SELECT AgentId,NumberOfAudit, YearMonth FROM #Data
) x

PIVOT
(
sum(NumberOfAudit)
FOR [YearMonth] IN (' + @cols + ')
) as p1
 

SELECT * from
(
SELECT AgentId,Score, YearMonth1 FROM #Data1
) x

PIVOT
(
sum(Score)
FOR [YearMonth1] IN (' + @cols1 + ')
) as p2
'
exec sp_executesql @stmt

上述查询的输出

我们的需要

Answer 1

老实说，这应该是您的表示层而不是 SQL 层；特别是当你想要合并单元格时（SQL 中不存在的概念）。

我个人会切换到条件聚合，而不是限制性的 PIVOT 运算符，然后执行如下操作：

DECLARE @SQL nvarchar(MAX),
        @CRLF nchar(2) = NCHAR(13) + NCHAR(10);

DECLARE @Delimiter nchar(3) = N',' + @CRLF;

WITH DateRanges AS(
    SELECT DISTINCT
           DATEADD(MONTH, DATEDIFF(MONTH,0,CreatedOn),0) AS StartDate,
           DATEADD(MONTH, DATEDIFF(MONTH,0,CreatedOn)+1,0) AS EndDate
    FROM dbo.TblDemoData)
SELECT @SQL = N'SELECT DD.AgentID,' + @CRLF + 
              STRING_AGG(N'       COUNT(CASE WHEN DD.CreatedOn >= ' + QUOTENAME(CONVERT(varchar(8),DR.StartDate,112),'''') + N' AND DD.CreatedOn < ' + QUOTENAME(CONVERT(varchar(8),DR.EndDate,112),'''') + N' THEN 1 END) AS ' + QUOTENAME(CONCAT(YEAR(DR.StartDate),'-',DATENAME(MONTH,DR.StartDate),N'-Audits')) + N',' + @CRLF +
                         N'       SUM(CASE WHEN DD.CreatedOn >= ' + QUOTENAME(CONVERT(varchar(8),DR.StartDate,112),'''') + N' AND DD.CreatedOn < ' + QUOTENAME(CONVERT(varchar(8),DR.EndDate,112),'''') + N' THEN AchievedScore* 1. ELSE 0 END) / ' + @CRLF +
                         N'       SUM(CASE WHEN DD.CreatedOn >= ' + QUOTENAME(CONVERT(varchar(8),DR.StartDate,112),'''') + N' AND DD.CreatedOn < ' + QUOTENAME(CONVERT(varchar(8),DR.EndDate,112),'''') + N' THEN MaximumScore ELSE 0 END) AS ' + QUOTENAME(CONCAT(YEAR(DR.StartDate),'-',DATENAME(MONTH,DR.StartDate),N'-Score')),@Delimiter) WITHIN GROUP (ORDER BY DR.StartDate) + @CRLF +
              N'FROM dbo.TblDemoData DD' + @CRLF + 
              N'GROUP BY DD.AgentId;'
FROM DateRanges DR;

--PRINT @SQL; Your debugging best friend

EXEC sys.sp_executesql @SQL;

请注意，这不会按照您要求的顺序给出列，但是，列的顺序没有意义，并且（再次）应该在您的表示层中进行控制。
