You can‘t specify target table ‘表名‘ for update in FROM clause
mysql执行删除语句时提示You can't specify target table '表名' for update in FROM clause,意思是说不能依据某字段值做判断再来更新某字段的值，修改sql语句：
DELETE from ntm_third_user where id in (
SELECT a.id from
(SELECT t.id FROM `ntm_third_user` t LEFT JOIN t_s_base_user u on t.user_id = u.id
where u.id is null) a
)，成功删除。
或者
delete a from ntm_third_user a left join t_s_base_user b on a.user_id = b.id where b.id is null
