Sql 对于相同的销售id，如何从两个具有相等总和的不同表中获取数据？

我有以下两个表格：

saleid

是常用列。我可以单独获得每个表的总计：

select saleid, sum(quantity) 
from table1
group by saleid;

select saleid, sum(extracted) 
from table2
group by saleid;

我需要将表2中提取的数量总和与表1中每次销售的数量总和进行比较

我可以使用哪种SQL Server或SQL工具来连接sum查询的输出并获得如下结果：

尝试以下带有内部联接和子查询的查询：

select a.saleid, quantity ,extracted from
(select saleid, sum(quantity) as quantity from table1 group by saleid)a
inner join
(select saleid, sum(extracted) as extracted from table2 group by saleid)b
on a.saleid=b.saleid
group by a.saleid

假设两个表中的

saleid

相同，您可以通过列连接两个表，并通过下面的查询获取数据

select t1.saleid, 
       sum(t1.quantity) , 
       sum(t2.extracted)
  from table1 t1 join table2 t2 
    on t1.saleid = t2.saleid
group by t1.saleid;

试试这个：

select t1.saleid, t1.quantitySum, t2.extractedSum from
(Select saleid, sum(quantity) as quantitySum from table1 group by saleid)t1 
inner join (Select saleid, sum(extracted) as extractedSum from table2 group by saleid)t2 on t1.saleid= t2.saleid and t1.quantitySum=t2.extractedSum ;
