Question

建立数据库，插入数据

进行结果查询

SELECT COMM_NAME,ORDER_DATE,ORDER_TYPE,
LAG((SELECT SUM(ISNULL(QTY_IN,0))-SUM(ISNULL(QTY_OUT,0)) FROM TB_ORDER A WHERE A.ORDER_DATE <= B.ORDER_DATE AND A.ORDER_TYPE<=B.ORDER_TYPE AND A.COMM_NAME = B.COMM_NAME))OVER (PARTITION BY COMM_NAME  ORDER BY COMM_NAME) AS BEG_QTY,
SUM(ISNULL(QTY_IN,0)-ISNULL(QTY_OUT,0)) AS QTY,
(SELECT SUM(ISNULL(QTY_IN,0))-SUM(ISNULL(QTY_OUT,0)) FROM TB_ORDER A WHERE A.ORDER_DATE <= B.ORDER_DATE AND A.ORDER_TYPE<=B.ORDER_TYPE AND A.COMM_NAME = B.COMM_NAME GROUP BY COMM_NAME)AS END_QTY
FROM TB_ORDER B
GROUP BY COMM_NAME,ORDER_DATE,ORDER_TYPE
ORDER BY COMM_NAME,ORDER_DATE ASC

求看看，或者换种方法获取库存

Answer 1

;with t as (
    select *,ROW_NUMBER() over(partition by comm_name order by id) as nid 
    from [dbo].[TB_ORDER]
),t1 as (
    select *,0 as BEG_QTY,ISNULL(QTY_IN,0)-ISNULL(QTY_OUT,0) as QTY,ISNULL(QTY_IN,0)-ISNULL(QTY_OUT,0) as END_QTY from t where nid=1
    union all
    select b.*,a.END_QTY,ISNULL(b.QTY_IN,0)-ISNULL(b.QTY_OUT,0),a.END_QTY+ISNULL(b.QTY_IN,0)-ISNULL(b.QTY_OUT,0) from t1 a,t b where a.nid=b.nid-1 and a.COMM_NAME=b.COMM_NAME
)
select * from t1
order by COMM_NAME,ID

你是要这样的结果？
