查看用户us2的上级path   complete_path

select * from lc_c_user_path where user_id='us2';

查看用户us2的所有下级用户

select * from lc_c_user_path where complete_path like '%us2/us1/us0';

 

 某个开店用户下的客户数

select partent_user_id,count(1) as count from lc_c_customer where 1=1 GROUP BY partent_user_id

 当某个店铺开店,更新lc_c_customer表的partent_user_id字段，即更新当前开店用户的所有下级的partent_user_id,此partent_user_id为最近的已开店的上级的user_id

 partent_user_id可以通过获取user_id_path的第一个就是它的直接上级的已开店的partent_user_id
