Question

以下查询正在生成数据，但仅返回值的周数是过去四个月中的第10,11,12周。我需要能够获得过去12周的周数，即在枢轴部分使用的周数10,11,12,13,14,15,16,17,18,19,20,21,22但是公式像dateadd（周，-1，发票）不起作用

我正在使用sql server 2008 r2

                        [12] ) ) AS pvtmonth

Answer 1

而不是使用

DATEPART(week, Invoicedate)  as Tweek

您可以使用

-DATEDIFF(WEEK, CURRENT_TIMESTAMP, InvoiceDate) AS Tweek

这将显示现在和发票日期之间的差异，而不是发票日期的周数

选择数据透视表中的最近12周销售额
