mysql - 如何使用另一个条件(例如 "name"而不是mysql中的id)从共享id的数据库中删除行

Question

我已经在 phpmyadmin 中尝试过此操作，但它带来了此错误“#1109 - MULTI DELETE 中未知的表'training_session'”

我有两个表(athlete)和(training_session)。 athlete 的相关列是 name、id，training_session 的相关列是 athlete_id.

DELETE training_session  FROM training_session t
INNER JOIN athlete a
iN t.athlete_id = a.id
WHERE a.name = ‘Per Persen’;

MySQL 说:

1109 - Unknown table 'training_session' in MULTI DELETE

Answer 1

您需要使用FROM子句中定义的别名:

DELETE t
    FROM training_session t INNER JOIN
         athlete a
         ON t.athlete_id = a.id
WHERE a.name = 'Per Persen';
