内连接（单个表的多个外键）

Question

我需要你的帮助

我在mssql server database中有这些表：

match
---------------
matchid           int;
palyerA_fk        int;
playerB_fk        int;
playerA_scores    int;
playerB_scores    int;



players
---------------
id               int;
fullname         nvarchar;

我需要这个观点：

Resultsview
----------------
PlayerA_fullname  
PalyerA_scores 
PlayerB_fullname 
PlayerB_scores

请帮我创建该视图，谢谢

。

此查询未返回任何行：

select a.fullname as playerAfullname , b.fullname as playerBfull name ,
 match.playerA_scores , match.playerB_scores 
from match 
inner join players as a on match.palyerA_fk = a.id 
inner join players as b on match.palyerB_fk = b.id

Answer 1

检查

select a.fullname as playerAfullname , b.fullname as playerBfullname ,
m.playerA_scores , m.playerB_scores 
from match as m
inner join players as a on m.palyerA_fk = a.id 
inner join players as b on m.palyerB_fk = b.id
