1。Oracle中: select org_id from organizations start with org_id= :org_id connect by prior org_id=supervision_org_id order by supervision_org_id 2。Sql Functiong: FunctionNo SubFunctionNo SubFunctionType 01. systemadmin Privilege 0 01. sys

   1。Oracle中:

  select org_id

  from organizations

  start with org_id= :org_id

  connect by prior org_id=supervision_org_id

  order by supervision_org_id

  2。Sql Functiong:

  FunctionNo SubFunctionNo SubFunctionType

  01. systemadmin Privilege 0

  01. systemadmin subsysadmin 1(表示樹枝)

  subsysadmin subsys1 0(表示leaf)

  subsysadmin subsys2 0

  subsysadmin User 1

  User UserOne 0

  請教實現此層次結構輸出的函數(在oracle中可以使用connect by實現此功能)

  先謝了.

  3。sql语句实现:

  举例:

  declare @a table (TC_Id int,TC_PID int,TC_Name varchar(200))

  insert @a values(1,0,'中国')

  insert @a values(2,0,'美国')

  insert @a values(3,0,'加拿大')

  insert @a values(4,1,'北京')

  insert @a values(5,1,'上海')

  insert @a values(6,1,'江苏')

  insert @a values(7,6,'苏州')

  insert @a values(8,7,'常熟')

  insert @a values(9,6,'南京')

  insert @a values(10,6,'无锡')

  insert @a values(11,2,'纽约')

  insert @a values(12,2,'旧金山')

  declare @tmp1 table (TC_Id int,TC_PID int,TC_Name varchar(200),lev int)

  insert @tmp1 select *,1 from @a where tc_ID=1

  while exists(select 1 from @a a,@tmp1 b where a.tc_pid=b.tc_ID and a.tc_ID not in (select tc_ID from @tmp1))

  insert @tmp1 select a.*,1 from @a a,@tmp1 b where a.tc_pid=b.tc_ID and a.tc_ID not in (select tc_ID from @tmp1)

  select * from @tmp1
