Sql 如何通过关联这两个表来显示可用数量

我有两个表，tbl_storage_Depositor_Master和tbl_storage_Depositor_log，一个表的总数量为1000，另一个表的事务量为500300100

现在我想显示如下数据：

Date           issue quantity      available quantity
-----------------------------------------------------
20/10/2014          500                  500
21/10/2014          300                  200
21/10/2014          100                  100

我的问题是：

SELECT 
    mg.Godown_Name, [Bags_Weight],
    CONVERT(VARCHAR(10), ssd.[CreatedDate], 103) AS Date
FROM
    [tbl_storage_Depositor_log] AS sdl
INNER JOIN
    tbl_MetaData_GODOWN AS mg ON sdl.Godown_ID = mg.Godown_ID
INNER JOIN
    tbl_MetaData_STACK AS ms ON sdl.Stack_ID = ms.Stack_ID
WHERE 
    Depositor_Id = '232700'

它返回出库数量、行李、仓库和日期等

date            godown            qty      availableqty
-------------------------------------------------------
20/10/2014         k1             500           ?
21/10/2014         k2             300           ?

如何计算可用数量

请帮忙

根据答案，但有错误。

一种方法是使用递归CTE

模式设置

更新尝试这样更改您的查询

您好，我正在使用以下代码，但出现错误…Msg 240，级别16，状态1，行1类型在递归查询cte1的\u包的第\u列中的锚和递归部分之间不匹配。Msg 240，级别16，状态1，行1类型在递归查询cte1的rn列中的锚和递归部分之间不匹配。Msg 240，级别16，状态1，行1类型在递归查询cte1的CreatedDate列中的锚和递归部分之间不匹配。Msg 240，级别16，状态1，行1类型在列available_quantity中的锚定和递归部分之间不匹配o@user3373573-现在更新支票。你完全搞乱了ctethank现在只有一个错误消息240，级别16，状态1，行1类型在递归查询cte1的可用数量列中的锚和递归部分之间不匹配。
