Can't specify target table for update in FROM clause

UPDATE tbl SET col = (
  SELECT ... FROM (SELECT.... FROM) AS x);

额外嵌套了一个 SELECT 语句

例如LeetCode 中的 Delete Duplicate Emails

正解：

DELETE
FROM
    Person
WHERE
    id NOT IN ( SELECT id FROM ( SELECT min( id ) AS id FROM Person GROUP BY email ) AS m );

错解：

DELETE
FROM
    Person
WHERE
    id NOT IN ( SELECT min( id ) AS id FROM Person GROUP BY email );
