导读：--由父项递归下级? with cte(id,parentid,text)? as? (--父项? select id,text from treeview where parentid = 450? union all? --递归结果集中的下级? select t.id,t.parentid,t.text from treeview as t? inner join cte as c on t.parentid = c.id? )? s

--由父项递归下级? with cte(id,parentid,text)? as? (--父项? select id,text from treeview where parentid = 450? union all? --递归结果集中的下级? select t.id,t.parentid,t.text from treeview as t? inner join cte as c on t.parentid = c.id? )? select id,text from cte? ---------------------? --由子级递归父项? with cte(id,text)? as? (--下级父项? select id,text from treeview where id = 450? union all? --递归结果集中的父项? select t.id,t.text from treeview as t? inner join cte as c on t.id = c.parentid? )? select id,text from cte
