Mysql 将两列与另一个表的相同字段联接

我对从用户表中获取发送方和接收方名称的mysql查询有一个问题

下面是

用户匹配列表的结构


这是
users
表


我想将senderId与用户表联接，并将firstname+lastname作为senderName
与receiverId相同，获取名称作为receiverName
请引导我
谢谢
听起来你想要两个
加入
s:

select uml.*,
       concat(us.firstname, ' ', us.lastname) as sendername,
       concat(ur.firstname, ' ', ur.lastname) as receivername,
from user_match_list uml join
     users us
     on uml.sendid = us.id join
     users ur
     on uml.receiverid = ur.id;

应使用两个联接：

SELECT us.firstName + ' ' + us.LastName,
       us2.firstName + ' ' + us2.LastName
FROM dbo.user_match_list AS um
INNER JOIN dbo.Users AS us ON um.senderId = us.Id
INNER JOIN dbo.Users AS us2 ON uml.receiverId = us2.Id
