当其中一个表不包含行

Question

我使用以下MYSQL从两个不同的表中删除记录：

DELETE rfw_leaguepos, rfw_events 
FROM rfw_leaguepos 
INNER JOIN rfw_events 
ON rfw_events.official = rfw_leaguepos.fk_official 
WHERE rfw_leaguepos.fk_official = 11 && rfw_leaguepos.league = 1

如果rfw_leaguepos和rfw_events表都包含行，则一切正常。我希望它能从两个表中删除行。

我非常感谢大家的帮助。谢谢!!

Answer 1

我相信我明白了！我将查询从INNER JOIN更改为LEFT OUTER JOIN。这似乎有效。

 DELETE rfw_leaguepos, rfw_events FROM rfw_leaguepos LEFT OUTER JOIN rfw_events ON rfw_events.official = rfw_leaguepos.fk_official WHERE rfw_leaguepos.fk_official = 11 && rfw_leaguepos.league = 1
