[英]Medoo PHP Framework and joining multiple tables
Trying to join 3 tables: leagues, leagues_teams, and teams. 尝试加入3个表:Leagues,Leagues_teams和team。
With the query: 与查询:
$teams = $database->select(
'teams',
[
'[>]leagues_teams' =>
[
'fifa_id' => 'fifa_team_id'
],
'[>]leagues' =>
[
'fifa_league_id' => 'fifa_id'
]
], [
'teams.fifa_id',
'teams.name',
'teams.rating'
], [
'ORDER' => 'teams.name ASC'
]
);
Which results in the following query: 这将导致以下查询:
SELECT "teams"."fifa_id","teams"."name","teams"."rating"
FROM "teams"
LEFT JOIN "leagues_teams" ON "teams"."fifa_id" = "leagues_teams"."fifa_team_id"
LEFT JOIN "leagues" ON "teams"."fifa_league_id" = "leagues"."fifa_id"
ORDER BY "teams"."name" ASC
When adding the second LEFT JOIN , it should join with leagues_teams.fifa_league_id=leagues.fifa_id and not teams.fifa_league_id 当添加第二个LEFT JOIN时 ,它应该与Leagues_teams.fifa_league_id = leagues.fifa_id而不是team.fifa_league_id一起加入
How would I go about this join? 我该如何加入?
In case someone was still having this problem, from MEDOO documentation: 如果有人仍然有此问题,请参阅MEDOO文档:
You can refer the previous joined table by adding the table name before the column. 您可以通过在列之前添加表名称来引用之前的联接表。
Example: 例:
"[>]album" => ["account.user_id" => "user_id"],
