Question

我需要你帮助创建一个INNER JOIN查询。

所以我目前有3张不同的表格。

1. Tablename: Players (ID - PLAYER_NAME)
   Entry:              1    PLAYER_TEST

-

2. Tablename: Maps (ID - MAP_NAME)
   Entry:           1  MAP_TEST

-

3. Tablename: Broken (ID - PLAYER_ID - MAP_ID)
                      1       1          1

我想执行一个查询，从表格中选择 NAME ：表格中的玩家和 NAME ：地图

这样我就可以得到输出：

[PLAYERNAME:'PLAYER_TEST', MAP_NAME:'MAP_TEST']

我已尝试过：

SELECT players.name, maps.name, xyz FROM broken INNER JOIN players ON recentlybroken.player_id=players.id ORDER BY xyz DESC LIMIT 0,100

Answer 1

我会试一试：

SELECT pp.name, m.name, o.date,FROM broken AS o INNER JOIN players AS pp ON o.player_id  = pp.id INNER JOIN maps         AS  m ON m.map_id = o.id DESC LIMIT 0,100;

Answer 2

你可以试试这个：

SELECT 
  players.players_name AS playerName,
  maps.map_name AS mapName
FROM players 
  LEFT JOIN broken ON broken.player_id=players.id 
  LEFT JOIN maps ON broken.map_id=maps.id 
ORDER BY columnname DESC 
LIMIT 0,100

SQL Query Inner Join获取2项
