我正在使用另一个Stackoverflow用户帮助我的以下查询，这对我来说是全新的：

"SELECT CONCAT(u1.firstname,' ',u1.lastname) as sender,CONCAT(u2.firstname,' 
',u2.lastname) as receiver, t.points as points FROM transactions t INNER JOIN users u1 ON 
u1.id=t.sender_id INNER JOIN users u2 ON u2.id=t.receiver_id ORDER BY date DESC limit 5"

它工作正常，但我意识到我没有从数据库中获得值
