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語句實現：
舉例：
declare @a table (TC_Id int,TC_PID int,TC_Name varchar(200))
insert @a values(1,0,'中國')
insert @a values(2,0,'美國')
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,'江蘇')
insert @a values(7,6,'蘇州')
insert @a values(8,7,'常熟')
insert @a values(9,6,'南京')
insert @a values(10,6,'無錫')
insert @a values(11,2,'紐約')
insert @a values(12,2,'舊金山')
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
