How to retrieve Duplicate Rows only in a Table?
Suppose if a Table Name is "Education". It consists of
multiple columns. Then if we insert rows into this table
with duplicate records then how can we retrieve only
duplicate records from that table?
How well can multiple sessions access the same data
simultaneously ?

Hi,
I am new in oracle(SQL), could anyone help me in writing a
correct SQL.
Below is the table structure.
Table: Subsc
Fields:
1. Sub_no (this field will hold values of subscriber nos,
for e.g. S111111, S222222, S333333, S444444, etc.)
2. s_status (this field will hold values for different
status of subscriber, for e.g. 'A', 'S', 'C', etc.)
3. cus_id (this field will hold values of bill nos for e.g.
11111111, 22222222, 33333333, 44444444, etc.)
Table: Bill
Fields:
1. Bill_no this field will hold values of bill nos for e.g.
11111111, 22222222, 33333333, 44444444, etc.)
2. b_status = (this field will hold values for different
status of bill for e.g. 'O', 'C', 'S', etc.)
Note:
1. The Sub_no is a Primary key of Subsc table.
2. The cus_id is a foreign in Subsc table (referred from
Bill_no field of Bill table)
3. The Bill_no field is the Primary key of Bill table.
Query A --> I wrote a query to select cus_id/Bill_no which
is in status open (b_status = 'O') and having more than two
active subscriber (i.e. S_status = 'A') in it ( i.e. more
the two subscribers in same bill).
select s.cus_id
from subsc s
where exists (select 1 from bill
where bill_no = s.cus_id
and b_status = 'O')
and s_status = 'A'
group by s.cus_id
having count(sub_no) = 2
Problem : The above query will give the cus_id (or rather
bill_no) which are in open status (b_status ='O) and which
are having TWO ACTIVE Subscribers (s_status ='A') in it.
However, this query will also lists the cus_id/bill_no
which are having more than TWO subscribers in it
(but only two subscriber will be in Active status (s_status
= 'A') and the others will be in s_status = 'C' or s_status
= 'S'.
Help needed: I want to write a query which will fetch ONLY
the cus_id/bill_no which are in open status (b_status ='O')
and which are having ONLY TWO ACTIVE subscribers (s_status
='A') in it.
B--> If I include the sub_no in the above query then NO row
are returned.
select s.cus_id, s.sub_no
from subsc s
where exists (select 1 from bill
where bill_no = s.cus_id
and b_status = 'O')
and s_status = 'A'
group by s.cus_id, s.sub_no
having count(sub_no) = 2
Help needed: I want to modify the above query which will
fetch ONLY the cus_id/bill_no which are in open status
(b_status ='O') and which are having ONLY TWO ACTIVE
subscribers (s_status ='A') in it ALONG with the sub_no.
Thanks a lot in advance.

Nitin
