Question

坚持这个查询。显然我下面的内容是错误的，但希望它能成为我想要做的事情。

SELECT branch, 
SUM(price * quantity) as "Office" FROM orders WHERE account LIKE "0%" 
and 
SUM(price * quantity) as Personal FROM orders WHERE account LIKE "1%" 
GROUP BY branch;

我确定我离开这里。

由于

Answer 1

在每笔金额中使用case：

select branch,
    sum(case when account like '0%' then price * quantity else 0 end) as Office,
    sum(case when account like '1%' then price * quantity else 0 end) as Personal
from orders
group by branch
