如何将第一列的数据作为行提取到标题和最后一列，因为行属于SQL查询中的标题？

问题描述

我在数据库中有3个表1.Warehouse，2.Product，3。Stock和我想从这三个表中获取数据。

Frirst Column是仓库名称，希望是库存中可用数量的标题。

第二列是无法复制的产品名称。

第三列是库存中的可用数量，必须与第一列仓库名称一起转换为行。 />

我想要预期的产量

我尝试过：

What I have tried:

SELECT       WareHouse.WareHouse_Name,
              Product.Cat_Name 'Product Name',
               SUM(Stock.Stock_In-Stock.Stock_Out) 'Available Quantity'

FROM            Stock INNER JOIN
                         Product_Catagory ON Stock.Cat_Id = Product_Catagory.Cat_ID INNER JOIN
                         WareHouse ON Stock.Warehouse_ID = WareHouse.WareHouse_ID

			GROUP BY    Product_Catagory.Cat_Name,WareHouse.WareHouse_Name
