You can't specify target table 'Person' for update in FROM clause

DELETE FROM Persons WHERE Id NOT IN  (SELECT MIN(Id)AS id FROM Persons GROUP BY Email) ;

You can't specify target table 'Person' for update in FROM clause

问题出现：同一个表里删除操作 和查询连同一起了

把后半句

(SELECT MIN(Id)AS id FROM Persons GROUP BY Email)

改

(select * from (SELECT MIN(Id)AS id FROM Persons GROUP BY Email)temp )
