Question

我最近介绍了一个名为with rollup的功能。我正在添加到我在Excel中用于趋势的报告中。问题是，我希望从最早到最新的日期订购t0.DocDate。

我读了一篇关于http://mangalpardeshi.blogspot.com/2009/08/rollup-and-order-by.html

的文章

我将代码格式化为与文章中的示例相似，但是在执行此操作后收到此错误消息：Conversion failed when converting date and/or time from character string.

无论如何都要在查询中更正此错误？如果是这样，任何能够帮助我的人都会非常感激！

我的代码是：

select  CASE WHEN GROUPING(t0.DocDate) = 1 THEN 'Total' ELSE T0.DocDate END AS 'DocDate',
        COUNT(T1.Itemcode) [# of Cross Sell],
        SUM(T1.Price * t1.Quantity) [Cross Sell $]

from ORDR t0 inner join RDR1 t1 on t0.DocEntry=t1.DocEntry

where t0.CANCELED <> 'Y'
and t1.U_SII_XSell = 'Y'

group by t0.DocDate WITH ROLLUP
order by GROUPING(t0.docdate);

如果您希望将DocDate用于汇总列值，则需要将VARCHAR转换为'Total'。该列不能同时为两种类型。

要按日期排序，并将“总计”列放在最后，您只需将t0.DocDate添加到ORDER BY子句中。

select  CASE WHEN GROUPING(t0.DocDate) = 1 THEN 'Total' ELSE Cast(T0.DocDate As Varchar(15)) END AS 'DocDate',
        COUNT(T1.Itemcode) [# of Cross Sell],
        SUM(T1.Price * t1.Quantity) [Cross Sell $]

from ORDR t0 inner join RDR1 t1 on t0.DocEntry=t1.DocEntry

where t0.CANCELED <> 'Y'
and t1.U_SII_XSell = 'Y'

group by t0.DocDate WITH ROLLUP
order by GROUPING(t0.docdate), t0.docdate;

我遇到了`与汇总`和`GROUPING'相结合的问题。如何纠正？
