我假设您使用的是SQL Server 2008 R2或更高版本。

以下是使用窗口函数执行此操作的方法：

with raw_data as (
  select
   warehousecode + convert(varchar(10), product_code) as productKey,
   warehousecode,
   product_code,
   stock_date,
   sum(quantity) as transaction_qty
  from Stock
  group by warehousecode, product_code, stock_date
)
select 
  productKey,
  warehousecode,
  product_code,
  stock_date,
  sum(transaction_qty) over (
    partition by productKey
    order by stock_date
  ) - transaction_qty as opening_stock,
  transaction_qty,
  sum(transaction_qty) over (
    partition by productKey
    order by stock_date
  ) as closing_stock
from raw_data
;
