Question

我正在尝试显示两个队伍在比赛结果页面上显示的头对头胜利记录。这是一个累积的计数，将在每场比赛之后在竞争团队之间发生变化。我需要定义'Team'和'Opponent'变量来运行查询，但我似乎无法让它工作。 $ GameID变量通过GET方法传递，但我需要将查询的Team和Opponent变量设置为特定GameID的Team和Opponent。

SELECT @team := Team, @opponent := Opponent FROM MatchDetails2017 WHERE GameID = $GameID AND HA = 'H')

                                            SELECT @Team, @Opponent,
                                            COUNT(*) AS Played,
                                            SUM(WL LIKE 'W%') AS Won,
                                            SUM(WL LIKE 'L%') AS Lost,
                                            SUM(WL = 'D') AS Drawn 
                                            FROM MatchDetails2017 
                                            WHERE Team = '@Team'
                                            AND Opponent = '@Opponent'
                                            AND GameID <= $GameID
                                            ");
