对于我的实习，我在休息时间安排比赛（台球、FIFA、飞镖等）
我制作了一个包含所有玩家的数据库以及一个包含游戏和获胜者的列表。
Players (p_id PK, name)
Games (g_id PK, player_one FK, player_two FK)
Winners (g_id FK, winner FK)
因此，在游戏中，您可以选择玩家，而根据获胜者，您可以从玩家中选择获胜者。
如何在表格中显示玩家的姓名而不是玩家的 ID？
就像是
SELECT
g.g_id,
p1.name as `player_one`,
p2.name as `player_two`
FROM Games g
INNER JOIN Players p1
ON p1.p_id = g.player_one
INNER JOIN Players p2
ON p2.p_id = g.player_two
为您的游戏桌和
SELECT
w.g_id,
p.name as `winner`
FROM Winners w
INNER JOIN Players p
ON p.p_id = w.winner
为您的赢家表
并将这三者结合在一起
SELECT
g.g_id
,p1.name AS `player_one`
,p2.name AS `player_two`
,pw.name AS `winner`
FROM Games g
INNER JOIN Players p1
ON p1.p_id = g.player_one
INNER JOIN Players p2
ON p2.p_id = g.player_two
LEFT JOIN Winners w
ON w.g_id = g.g_id
LEFT JOIN Players pw
ON pw.p_id = w.winner
