如何在SQL

Question

我试图找出过去4周没有销售的商店数量。由于网格在DevExpress中的结构方式，我需要将周显示为Wk1，Wk2，Wk3，Wk4作为列（这些列中的数据将是零销售商店的商店数）。

现在我的数据已连续销售财政周。我需要它看起来基本上就像：

Vendor        | Store  | City   | State | Category     | Wk1 | Wk2 | Wk3| Wk4
------------------------------------------------------------------------    
Prairie Farms | #16141 | Adrian | MI    | 2% Gallon    |  1  |  0  |  1  |  1
Prairie Farms | #16141 | Adrian | MI    | Whole Gallon |  1  |  1  |  0  |  0

而不是

Vendor        | Store  | City   | State | Category     | Sale Cal Wk | Sale Fiscal Wk
--------------------------------------------------------------------------    
Prairie Farms | #16141 | Adrian | MI    | 2% Gallon    | 2015-10-23  | 38
Prairie Farms | #16141 | Adrian | MI    | Whole Gallon | 2015-10-23  | 38

我已经包含了迄今为止有效的代码。我有一个计数（存储）功能作为＆＃39; ZeroStore＆＃39;在最终的select语句中，将商店指示为零销售商店。
