。。怎么没人额- - #

-----建表
create table staff(id int,managerid int)
create table newtable(ID int,[Path] varchar(100))
----------所有id
create proc allid
as
begin

declare @nid int
declare cursor_id cursor for select id from staff
open cursor_id
fetch next from cursor_id into @nid
while(@@fetch_status=0)
begin

exec ppp @nid,@nid

fetch next from cursor_id into @nid
end
close cursor_id
deallocate  cursro_id

end



----------------单个id执行
create proc ppp
(@id int,@child_id int)
as
begin
  declare @managerid int
  select @managerid=managerid from staff where id=@child_id
  
  if not exists(select 1 from newtable where ID=@id)
  begin
  select 1
  insert into newtable(ID,[Path])
  values(@id,cast(@id as varchar))
  end

  if(@managerid is null)
  select 2
  else
  begin
  select 3
  update newtable set [Path]=[Path]+','+cast(@managerid as varchar) where ID=@id
  exec ppp @id,@managerid
  end
end

-----测试，执行存储过程allid即可
