Question

我正在使用此查询获取过去12个月的销售额。

SELECT *
FROM (SELECT
    gp_etablissement [ETABLISSEMENT],
    datename(month, dateadd(m,-1,getdate())) [Month], 
    COUNT(1) [Sales Count]
    FROM PIECE
    GROUP BY gp_etablissement,
    datename(month, dateadd(m,-1,getdate()))) AS MontlySalesData
PIVOT( SUM([Sales Count])   
    FOR Month IN ([January],[February],[March],[April],[May],
    [June],[July],[August],[September],[October],[November],
    [December])) AS MNamePivot

我收到此错误：

每个GROUP BY表达式必须至少包含一列外部参考。

我更改了分组依据中的许多列，但存在相同的问题。

Answer 1

使用以下代码消除错误。当分组依据使用日期部分时，数据透视表不适用于子查询。

;WITH CTE
AS
(
SELECT
    gp_etablissement [ETABLISSEMENT],
    datename(month, dateadd(m,-1,getdate())) [Month], 
    COUNT(1) [Sales Count]
    FROM PIECE
    GROUP BY gp_etablissement,
    datename(month, dateadd(m,-1,getdate())) 
)
SELECT *
FROM CTE
PIVOT( SUM([Sales Count])   
    FOR Month IN ([January],[February],[March],[April],[May],
    [June],[July],[August],[September],[October],[November],
    [December])) AS MNamePivot

数据透视表和分组依据
