我有下表称为 CustomerDetails

我正在尝试编写一个查询，该查询为具有以下条件的客户趋势提供一个额外的列

Case When *SalesQty2012* is higher than *SalesQty2011* THEN "Increasing"
Case When *SalesQty2011* is higher than *SalesQty2012* THEN "Decreasing"
Case When *SalesQty2011* is equal 0 (No Sales) AND  *SalesQty2012* grater than 0 THEN "NEW"
Case When *SalesQty2012* is equal 0 (No Sales) AND  *SalesQty2011* grater than 0 THEN "Lost"

这是我写的最后两个条件没有正确应用的地方

    Select top 10 [Status],DivisionCode,CustomerCode,CustomerName,
SalesQty2012=ISNULL(SalesQty2012,0),
SalesQty2011=ISNULL(SalesQty2011,0),
CustomerTrend= ( CASE WHEN SalesQty2012>SalesQty2011 THEN 'Increasing'
WHEN SalesQty2012<=SalesQty2011 THEN 'Decreasing'
WHEN SalesQty2011=0 and SalesQty2012>0 THEN 'NEW'
WHEN (SalesQty2011>0 and SalesQty2012 =0) THEN 'Lost'  else 'Nothing' END)
from dbo.CustomerMasterSalesView

order by customerTrend

我需要您的帮助来告诉我如何编写查询来处理 New and Lost 场景的案例。

非常感谢阿里

我在上面的查询中遇到了一个问题，我需要确保 salesQty2012 期间与 SalesQty2011 相同，因为 2012 年的销售仍未结束，我的比较将是错误的。我的问题是如何编写查询以根据当前时间段带来 salesqty 2011。我的原始查询以获取上述数据：

From ACCMST a full join accsub b on    a.accode=b.accode where  a.GRPCD LIKE 'SDD%' and a.LOCK=0

从上面的视图我使用数据从下面的查询中显示客户销售趋势

      WHEN SQ.SalesQty2012 > SQ.SalesQty2011 THEN 'Increasing'
      WHEN SQ.SalesQty2012 <= SQ.SalesQty2011 THEN 'Decreasing'

      ELSE 'Nothing' 
    END
from [Sales_Data10] WHERE InvoiceDate BETWEEN '2011-01-01' AND '2012-12-31'

  CROSS APPLY (
              SELECT ISNULL(SV.SalesQty2011, 0) AS SalesQty2011, 
                     ISNULL(SV.SalesQty2012, 0) AS SalesQty2012
              ) SQ

总结一下，我需要编写查询以确保 2012 年和 2011 年的销售数量在同一时间段内。

谢谢阿里

该案例从左到右进行评估，当有匹配时，它会采用它并且不再查找。

尝试将最后两个when子句移到顶部。

Select top 10
  [Status],
  DivisionCode,
  CustomerCode,
  CustomerName,
  SalesQty2012=ISNULL(SalesQty2012,0),
  SalesQty2011=ISNULL(SalesQty2011,0),
  CustomerTrend= 
    (
     CASE
      WHEN SalesQty2011 = 0 and SalesQty2012 > 0 THEN 'NEW'
      WHEN SalesQty2011 > 0 and SalesQty2012 = 0 THEN 'Lost'
      WHEN SalesQty2012 > SalesQty2011 THEN 'Increasing'
      WHEN SalesQty2012 <= SalesQty2011 THEN 'Decreasing'
      ELSE 'Nothing' 
     END
    )
from dbo.CustomerMasterSalesView
order by customerTrend

更新

对于列NULL中的值，您SalesQty*也需要ISNULL在CASE表达式中使用。
这是一个CROSS APPLY用于获取0而不是NULL.

SELECT TOP 10
  SV.[Status],
  SV.DivisionCode,
  SV.CustomerCode,
  SV.CustomerName,
  SQ.SalesQty2012,
  SQ.SalesQty2011,
  CustomerTrend= 
    (
    CASE
      WHEN SQ.SalesQty2011 = 0 and SQ.SalesQty2012 > 0 THEN 'NEW'
      WHEN SQ.SalesQty2011 > 0 and SQ.SalesQty2012 = 0 THEN 'Lost'
      WHEN SQ.SalesQty2012 > SQ.SalesQty2011 THEN 'Increasing'
      WHEN SQ.SalesQty2012 <= SQ.SalesQty2011 THEN 'Decreasing'
      ELSE 'Nothing' 
    END
    )
FROM CustomerMasterSalesView SV
  CROSS APPLY (
              SELECT ISNULL(SV.SalesQty2011, 0) AS SalesQty2011,
