我有我的选择代码：
SELECT m.`genmat_id`,m.`mat_type`,m.`mat_name`, m.`category`, m.`size`, m.`req_qty`, m.`stock_received`, m.`stock_released`, m.`release_approval`,
(select sum(stock_received) - sum(stock_released)
from genmaterial m2
where m2.mat_name = m.mat_name and
m2.genmat_id <= m.genmat_id
) as Stock_balance,
(case when (select sum(stock_received)
from genmaterial m2
where m2.mat_name = m.mat_name and
m2.genmat_id <= m.genmat_id
) = req_qty
then 'Complete'
when req_qty = 0 then ''
else 'Incomplete'
end) as status,
m.`date`,
s.`sup_name`
FROM `genmaterial` m LEFT JOIN
`supplier` s
on s.sup_id = m.sup_id
ORDER BY m.`genmat_id` ASC
OUTPUT（忽略Full Textts列）：
Full Texts genmat_id mat_type mat_name category size req_qty stock_received stock_released release_approval Stock_balance status date sup_name

mat_id 74是由mat_type = pur标识的新请求
并且mat_id 77是在stock_received和mat_type = Raw上接收40的请求。现在，stock_balance恰到好处，因为它总结了material + the stock_received之前的总和。
我的问题：如何让状态完整 有这种情况吗？
它会在柜台内mat_type=raw时汇总stock_received
如果counter=req_qty有status=complete
我现有的代码会在Stock_balance = req_qty时生成状态。
我该怎么做counter = req_qty
而stock_balance是来自每个mat_name的计数器的总和
stock_balance - stock_released（stock_out）
喜欢（参见计数器专栏）： 计数器只计算每个新mat_type = pur
的stock_receivedFull Texts genmat_id mat_type mat_name category size req_qty stock_received counter stock_released release_approval Stock_balance status date sup_name
