SQL 服务器：多列的动态数据透视

Question

我有一个 table 看起来像这样：

DECLARE @Temp TABLE (
 fldID bigint
,fldYear bigint
,fldMonth bigint
,fldMonthName nvarchar(350)
,fldPayrollId bigint
,fldFullName nvarchar(350)
,fldDailyWage float
,fldMonthlyWage  float
,fldkarkardDay  float
,fldPriceMaskan  float
,fldPriceChild float
,fldPriceFood  float
,fldAllAdditions  float
,fldPriceTax  float
,fldPriceSanavat  float
,fldPriceEzafeKari  float
,fldPriceEidiPadash  float
,fldEmployeeShare  float
,fldEmployerShare  float
,fldUnemploymentShare  float
,fldSumEmployer  float);

insert @Temp(fldID, fldYear, fldMonth, fldMonthName, fldPayrollId, fldFullName, fldDailyWage, fldMonthlyWage , fldkarkardDay , fldPriceMaskan , fldPriceChild, fldPriceFood , fldAllAdditions , fldPriceTax , 
fldPriceSanavat, fldPriceEzafeKari , fldPriceEidiPadash , fldEmployeeShare , fldEmployerShare , fldUnemploymentShare , fldSumEmployer  )
values(1, 1400, 2, N'February', 212, N'500000', N'6500', N'29', N'52000', N'98750', N'1900000', N'900000', N'30000', N'900000', N'60000', N'650000', N'0', N'0', N'1900000', N'256000', N'256000'),(2, 1399, 3, N'March'   , 214, N'5200000', N'0', N'30', N'65900', N'6520', N'1900000', N'1000', N'98500', N'1900000', N'1900000', N'1900000', N'0', N'1900000', N'0', N'256000', N'0'),(3, 1400, 4, N'April'   , 216, N'62200000', N'35600', N'30', N'87900', N'65000', N'0', N'6520', N'1900000', N'1900000', N'0', N'1900000', N'1900000', N'1900000', N'1900000', N'256000', N'25600'),(4, 1399, 5, N'May'       , 218, N'522000', N'85000', N'2800', N'65400', N'52200', N'0', N'14780', N'1900000', N'1900000', N'0', N'1900000', N'0', N'1900000', N'1900000', N'256000', N'0')

我正在按如下方式尝试调整它：

我的代码如下，但是pivot命令无法识别代码和正确的输出

SELECT 
     N'parameter' parameter
    ,p.fldMonthName 
    ,p.fldCols
FROM 
(
    SELECT 
        N'[fldDailyWage],[fldMonthlyWage],[fldkarkardDay],[fldPriceMaskan],[fldPriceChild],[fldPriceFood],[fldAllAdditions],[fldPriceTax]' fldCols
        ,* 
    FROM @Temp where fldYear = 1399
) x
PIVOT  
(
    count(fldID)
    FOR fldMonthName IN (fldCols)
) p

Answer 1

我将按列参数分组使用 unpivot，如下所示：

Select u.parameter, Sum(Case When fldMonth=2 Then u.value End) As 'February',
                    Sum(Case When fldMonth=5 Then u.value End) As 'May'
From
(
select fldMonth, [fldDailyWage],[fldMonthlyWage],[fldkarkardDay],[fldPriceMaskan],[fldPriceChild],[fldPriceFood],[fldAllAdditions],[fldPriceTax]
from @Temp) t
unpivot
( 
  value
  for parameter in ([fldDailyWage],[fldMonthlyWage],[fldkarkardDay],[fldPriceMaskan],[fldPriceChild],[fldPriceFood],[fldAllAdditions],[fldPriceTax])
) u
Group by u.parameter
