我想创建sql余额计算我有4个表这样的股票，stocklist，sub，子列表结果不工作。平衡错误看我的代码

SELECT cc.mm,cc.dd,cc.name,cc.q1,cc.q2,cc.staff,(select sum(q1) - sum(q2) 
    from (SELECT s1.qty AS q1,"" AS q2,i.item_id,s2.receive_date as dd,concat('A',s2.id) AS mm
             FROM  mitem i 
             JOIN mstocklist s1 ON s1.item_id=i.item_id
             JOIN mstock s2 ON s2.id=s1.stock_id
             JOIN msupplier sp ON sp.supplier_id=s2.supplier_id
             WHERE s2.receive_date BETWEEN '2016-10-01' AND '2017-09-30'
             AND i.item_id='3' UNION SELECT "" AS q1,s1.qty AS q2,i.item_id,s2.receive_date as dd,concat('B',s2.id) AS mm
             FROM mitem i 
             JOIN msublist s1 ON s1.item_id=i.item_id
             JOIN msub s2 ON s2.id=s1.sub_id
             WHERE s2.receive_date BETWEEN '2016-10-01' AND '2017-09-30'
             AND i.item_id='3') as a where a.item_id=cc.item_id and a.mm <= cc.mm) as balance FROM(SELECT i.item_id,s2.receive_date as dd,i.name,s1.qty AS q1,"" AS q2,s2.staff_receive AS staff,concat('A',s2.id) AS mm FROM mitem i

             AND i.item_id='3') as cc ORDER BY dd ASC

如果我没有记错（你的代码很难得到）：有FROM没有选择。这一个：

FROM (SELECT i.item_id
             , s2.receive_date AS dd
             , i.name
             , s1.qty AS q1
             , "" AS q2
             , (s1.qty*i.unitcost) AS cost
             , s2.staff_receive AS staff
             , s2.id AS mm
