MySQL-从多个表中选择总和,mysql,Mysql,任何人都可以帮助完成以下简短的mysql查询： SELECT mr.matcode, IFNULL(SUM(mr.mr_qty),0) AS total_mr_qty, IFNULL(SUM(mb.out_qty), 0) AS out_qty FROM mr INNER JOIN material m ON mr.matcode = m.matcode INNER JOIN job_order jo ON mr.jo_no = j

任何人都可以帮助完成以下简短的mysql查询：

SELECT 
   mr.matcode, 
   IFNULL(SUM(mr.mr_qty),0) AS total_mr_qty, 
   IFNULL(SUM(mb.out_qty), 0) AS out_qty
FROM mr 
   INNER JOIN material m

但是，使用上述查询，结果是：

-------------------------------------------------------------
600NH04R0003220    7400                     4400

列mr_数量结果将加倍，这是不正确的
有人能告诉我上面的问题是什么吗
更新1：添加物料表

更新2：在第1点添加测试小提琴：

left outer JOIN (select doc_no, item_no, matcode, sum(out_qty) out_qty, jo_no from min_out_body group by jo_no) mb
将根据您的表结构/数据生成错误。这是你在小提琴上阐明的。所以没问题
第2点：

mr_no matcode mr_qty jo_no ---------------------------------------------------------- MR001 600NH04R0003220 2800 S6914-S01 MR002 600NH04R0003220 1800 S6915-S01

left outer JOIN (select doc_no, item_no, matcode, sum(out_qty) out_qty, jo_no from min_out_body group by jo_no) mb
将加入所有mb，其中有两个条目用于相同的作业编号“S6914-S01”。这将从另一个表中获取行两次
第3点：

更正：

输出也可能是基于jou_no的。请检查。
请检查“材料”表的内容和结构？sql中引用了5个表，但列出了4个表。我对表min_out_body和mr进行了更正，将mr_no添加到它们中，并创建了一个fiddle。尝试更正，但它是一个错误。我也编辑了我的答复-你应该跳过第1点。剩下的将解释你应该做些什么来获得你想要的结果。如果您希望输出列中也有jou_no，那么也要小心。在这种情况下，输出将有更多行（每个jou_no也有）。尝试更新fiddle并进行更正，但它会生成错误，我是否遗漏了某些内容？您错过了第三次联接的条件1和条件2。勾选此项后，请将其标记为choosen Response，并向上投票。
