Identify Different Groups in the Organization (Group the Same data together)

Question

Version : Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production
Help me in Identifying the groups(different Sectors) in the Organization
Each Group will have the same Group id if  We_org_id , We_addr_id or We_org_id , Ein Matches
In the below Example Row 1 and 2 Are linked with We_org_id , We_addr_id
and row 2 and 3 are linked with We_org_id , Ein  so all the three rows has the same groupid
Included Output Required.
Example
311    563          72-1500000    2
311    563          72-1500001    2
311    565          72-1500001    2

Answer 1

It would be nice to know the roots. I did assume two with
start with we_addr_id in (
select min(we_addr_id)
from org_mismatch group by we_org_id
Otherwise it could taken a while ...
That below doesnt really work ..
select
WE_ORG_ID
,WE_ADDR_ID
,EIN
,dense_rank() over (partition by WE_ORG_ID order by r) grp
from (
select
WE_ORG_ID
,WE_ADDR_ID
,EIN
,connect_by_root WE_ADDR_ID r
from ORG_MISMATCH  
connect by nocycle
prior we_org_id = we_org_id
and (
(prior we_addr_id = we_addr_id and prior ein < ein)
or
(prior ein = ein and prior we_addr_id < we_addr_id)
start with we_addr_id in (
select min(we_addr_id)
from org_mismatch group by we_org_id
group by
WE_ORG_ID
,WE_ADDR_ID
,EIN
,r
order by
WE_ORG_ID
,WE_ADDR_ID
,EIN
,R
WE_ORG_ID
WE_ADDR_ID
EIN
