Question

现在我有一个cte，它给了我每个销售人员每月的总销售额。我希望专门使用pivot为每个月列和列出的销售人员，以便更轻松地显示每个列下的总销售额一个月。

QUERY：

WITH SalesCTE (Salesperson, Date, TotalSales) AS ( SELECT FirstName + ' ' + LastName AS 'SalesPerson', CAST(YEAR(OrderDate) AS nvarchar(10)) + '-' + DateName(MONTH,OrderDate) AS 'Date', SUM(TotalDue) FROM Person.Person p JOIN Sales.SalesOrderHeader s ON p.BusinessEntityID = s.SalesPersonID GROUP BY FirstName, LastName, OrderDate ) SELECT SalesPerson, Date, TotalSales FROM SalesCTE ORDER BY Date, SalesPerson

此时输出：

David Campbell 2011-December 78223.3018 Garrett Vargas 2011-December 10254.8552 Jillian Carson 2011-December 52586.674 José Saraiva 2011-December 119678.9211 Linda Mitchell 2011-December 6167.1672 Michael Blythe 2011-December 71792.8437

理想情况下我想要这个：

December-11 January-12 February-12 …. David Campbell 78223.3018 73343.3652 77431.389 Garrett Vargas 10254.8552 176300.293 46954.6224 Jillian Carson 52586.674 300998.1522 158997.3466 José Saraiva 119678.9211 180684.8446 182343.3114 Linda Mitchell 6167.1672 305145.2225 205684.0069

列表中还有很多其他月份和销售人员，之前我没有做过这样的事情。看了几个小时的支点，但却无法了解它们的工作方式。

Answer 1

将包含原始日期的新列的表插入新的临时表

SELECT *,CAST(DATES+'-01' AS DATE) ORGDATE 
INTO #NEWTABLE
FROM TEMP

现在声明变量以动态获取枢轴列

DECLARE @cols NVARCHAR (MAX)

SELECT @cols = COALESCE (@cols + ',[' + DATENAME(MONTH,ORGDATE)+'-'+RIGHT(CAST(YEAR(ORGDATE) AS
               VARCHAR(4)),2) + ']', 
              '[' + DATENAME(MONTH,ORGDATE)+'-'+RIGHT(CAST(YEAR(ORGDATE) AS VARCHAR(4)),2) + ']')
               FROM    (SELECT DISTINCT ORGDATE,[DATES] FROM #NEWTABLE) PV  
               ORDER BY ORGDATE

现在做转轴

DECLARE @query NVARCHAR(MAX)
SET @query = 'SELECT * FROM 
             (
                 SELECT NAME, DATENAME(MONTH,ORGDATE)+''-''+RIGHT(CAST(YEAR(ORGDATE)AS VARCHAR(4)),2) logdate, value 
                 FROM #NEWTABLE
             ) x
             PIVOT 
             (
                 SUM(value)
                 FOR logdate IN (' + @cols + ')
            ) p;' 

EXEC SP_EXECUTESQL @query

的 SQL FIDDLE

使用Month-YY格式进行旋转
