MySQL DELETE - 这个版本的MySQL还不支持'LIMIT＆amp; IN / ALL / ANY / SOME子查询'

Question

是一种重写此查询的方法，因此我不会收到此消息This version of MySQL doesn't yet support 'LIMIT & IN/ALL/ANY/SOME subquery'：

DELETE FROM city WHERE id IN (SELECT id FROM city_data LIMIT 10000);

任何想法？

Answer 1

您可以将查询更改为

DELETE
FROM city 
WHERE id IN (SELECT id FROM city_data )
LIMIT 10;

Answer 2

如果限制不是必须的，你可以

 delete c.* 
 from city as c
 inner join city_data as cd on cd.id = c.id;
