oracle中的connect,by,在sql,server中实现:sqlserver使用教程

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
