Sql server 使用SQL Server 2008 R2在两个日期之间透视表

我有下表：

例如：

插入一些记录：

insert into test values('2014-11-07','2014-12-01');

select * from test;

col_dt1     col_dt2
----------------------
2014-11-07  2014-12-01

预期结果：

col_dt1     col_dt2    07 November 2014  08 November 2014 .................... 01 December 2014
-----------------------------------------------------------------------------------------------
2014-11-07  2014-12-01       1                 0          ....................        1

为了在透视表中包含stuff列，我不得不获取两个日期之间的所有日期

DECLARE @Start_Date DATE, @End_Date DATE, @QUERY NVARCHAR(MAX), @SUBQUERY NVARCHAR(MAX), @ROWCOUNT int

CREATE TABLE #TempTable(
ID int IDENTITY(1,1) NOT NULL,
Start_Date date,
End_Date date, 
Dates NVARCHAR(50),
HasDate int
)
CREATE TABLE #TempTable2(
Start_Date date,
End_Date date, 
Dates NVARCHAR(50), 
HasDate int
)

SET @Start_Date = (SELECT TOP 1 col_dt1 from test)
SET @End_Date = (SELECT TOP 1 col_dt2 from test)

INSERT INTO #TempTable
SELECT 
@Start_Date as Start_Date,
@End_Date as End_Date,
RIGHT(REPLICATE('0', DAY(DATEADD(DAY,number,@Start_Date))) + CAST(DAY(DATEADD(DAY,number,@Start_Date)) AS NVARCHAR(2)), 2)
+' '+DATENAME(MONTH,DATEADD(DAY,number,@Start_Date))+' '+CONVERT(NVARCHAR(50),YEAR(DATEADD(DAY,number,@Start_Date))) as Start_Date,
HasDate =
      CASE 
         WHEN DATEADD(DAY,number,@Start_Date)=@Start_Date THEN 1
         WHEN DATEADD(DAY,number,@Start_Date)=@End_Date THEN 1
         ELSE 0
      END
FROM master..spt_values
WHERE type = 'P'
AND DATEADD(DAY,number,@Start_Date) <= @End_Date
INSERT INTO #TempTable2 SELECT [Start_Date],[End_Date],[Dates],HasDate FROM #TempTable

SELECT * FROM #TempTable

SET @QUERY=''
SET @QUERY+='SELECT * FROM #TempTable2
                PIVOT
                (
                    Max(HasDate)
                    FOR Dates IN ('

SET @SUBQUERY=''
SET @ROWCOUNT=1                 
WHILE @ROWCOUNT <= (SELECT COUNT(*) FROM #TempTable)
BEGIN
    SET @SUBQUERY=@SUBQUERY+'['+(SELECT CONVERT(NVARCHAR(50),Dates)as Dates FROM #TempTable WHERE ID=@ROWCOUNT)+']'
    IF (@ROWCOUNT<>(SELECT COUNT(*) FROM #TempTable))
    BEGIN
        SET @SUBQUERY=@SUBQUERY+','
    END
    SET @ROWCOUNT=@ROWCOUNT+1
END             
SET @QUERY=@QUERY+@SUBQUERY+')
                )AS tblPivot'


PRINT(@QUERY)
EXECUTE(@QUERY)

DROP TABLE #TempTable
DROP TABLE #TempTable2

您可以尝试此操作。

预期输出不正确clear@Pradeep，有两个日期，第一个和最后一个日期分别为2014-11-07和2014-12-01。我想显示从2014-11-07到2014-12-01的这些日期的数据透视表。它必须在列中显示这两个日期之间的所有日期。因此，这两个日期下的值必须为1，其他日期的值应为0@Meem如果您的表中再包含一行，例如2014-01-01、2014-01-31，该怎么办。在这种情况下，所需的输出是什么？@Meem在这种情况下，您可以考虑使用表值函数。Pivot用于旋转表值表达式。作为输入的不是表值表达式。它只是两个标量日期：开始日期和结束日期。
