Question

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）：

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_received
