我有三个表，user / team / user_team（多对多）
user
-----------
id name
1 Tom
2 Jerry
3 John
team
------------
id name
1 t1
2 t2
3 t3
user_team
---------------------
userid teamid isdeleted
1 t1 0 <----(0 means not deleted record, which can be searched out)
2 t2 1 <----(1 means deleted record, which can not be searched out)
我想获取所有团队记录信息以及相关的用户信息，如下所示
--------------
tid tname username
1 t1 Tom
2 t2
3 t3
您能告诉我如何编写sql语句吗？
对不起，我错了。我通过在团队表中再添加一条记录t3更新了我的问题。
试试这个：
Select a.id as tid
a.name as tname
b.name as username
from team a
LEFT JOIN user_team c on a.name = c.teamid and c.isdeleted = 0
LEFT JOIN user b on b.id = c.userid
