多個SELECT語句 - PHP + MySQL的

Question

表： 玩家： ID（PK），名稱，隊，波什

，對位： matchupID（PK），player1ID，player2ID
player1ID和2 FKs to Players.ID

我想選擇兩個球員的名字，但不能正確提取查詢。我不想在這裏工會。

有些事情，我也打開一個更好的建議來格式化我有兩個表。

$queryString = "SELECT Players.name FROM Players 
        INNER JOIN Matchup WHERE Players.ID = player1ID, 
        SELECT Players.name FROM Players 
        INNER JOIN Matchup WHERE Players.ID = player2ID"; 

Answer 1

您shoudl加入兩個時間播放器，而不是對決

$queryString = "select a.name, b.name from Matchup as c 
      Inner Join Players as a on c.player1ID = a.ID 
      Inner Join Players as b on c.player2ID = b.ID";
