SQL在查询结果中替换另一个表中的多个变量

Question

我有一个团队日程表,看起来像这样:

DBO.SCHEDULE

Game1_Time  |  Game1_Home_Team   | Game1_Away_Team 
===================================================
12:00:00    |         1          |         2

我想将团队值替换为另一个表中存在的相应团队:

DBO.TEAM

Team_Number  |  Team_Name
========================
    1        |  The Monsters
    2        |  Bug Bites

尝试这样做:如何在查询结果中用"The Monsters"和"Bug Bites"替换附表中的1&2？

Game1_Time  |  Home Team         | Away Team 
===================================================
12:00:00    |  The Monsters      |  Bug Bites

Answer 1

基本上只做两个连接一个用于主页名称和一个用于离开名称.

SELECT 
     s.Game1_Time, 
     t.Team_Name as 'Home Team', 
     t1.Team_Name as 'Away Team'
FROM `SCHEDULE` s
JOIN `TEAM` t on t.Team_Number = s.Game1_Home_Team
JOIN `TEAM` t1 on t1.Team_Number = s.Game1_Away_Team

我添加了反引号,因为schedule是一个关键字,所以只是为了不弄乱你应该在tablename上使用backtics
