计算用户消费总额， MySQL 查询问题请教？

    这是一个创建于 3292 天前的主题，其中的信息可能已经有所发展或是发生改变。

    目前有两表，一个用户信息表(users),一个消费记录表(shopping)。

    想要查询有消费记录的用户信息，并计算出消费总额。

    我尝试如下 select u.id,u.name,f.money from data.users u ,data.shopping s where s.users_id = u.id

    但这样查询出来的每条单独的消费记录和用户信息，我想将消费总金额合并 SUM(money),最终显示出每个用户的消费总金额，请问该如何写？

  • 消费
  • users
  • Data
  • 查询

    select shop.*,u.name,u.uid (select SUM(money) as s,id from shopping group by uid ) as shop,users where shop.id=u.users_id
