MySQL DELETE-此版本的MySQL尚不支持“ LIMIT＆IN / ALL / ANY / SOME子查询”

Question

是重写此查询的一种方法，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);

有任何想法吗？

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

如果不是必须的限制，则可以

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