将一个表的两列连接到另一表的一列

Question

I am trying to use my home_team and away_team fixture_id's to get their name values from a different table.

This works to get the name value of home_team

SELECT * FROM fixtures JOIN teams ON fixtures.home_teamID = teams.TeamID

To get the name value of the away team I have the following

SELECT * FROM fixtures JOIN teams ON fixtures.home_teamID = teams.TeamID 
JOIN teams ON fixtures.away_teamID = teams.TeamID

But this then returns a boolean

Answer 1

you should join the teams table two time using two different alias

  SELECT fixtures.* a.* , b.*
  FROM fixtures 
  JOIN teams a ON fixtures.home_teamID = a.TeamID
  JOIN teams b ON fixtures.home_teamID = b.TeamID
