Merge multiple rows to get single row result

Question

Hi,
Below is the sample data from my table USERINFO-
personid userid username orgid
1234 1235 TOM 1
2345 2346 HARRY 1
1111 2222 BOND     2
3333 4444 BERY 2
Now I want a query which can give me the following result-
personid userid username personid userid username orgid
1234 1235 TOM 2345 2346 HARRY     1
1111 2222 BOND     3333 4444 BERY 2
i.e., two records belonging to the same orgid should be merged into a single row resulset.
Please let me know the SQL query to get the desired result.
Thanks

SQL> select * from test_otn;
  PERSONID     USERID USERNAME                  ORGID
      1234       1235 TOM                           1
      2345       2346 HARRY                         1
      1111       2222 BOND                          2
      3333       4444 BERY                          2
SQL> select max(decode(rn, 1, personid, null)) person_id1,
  2        max(decode(rn, 2, personid, null)) person_id2,
  3        max(decode(rn, 1, userid, null)) user_id1,
  4        max(decode(rn, 2, userid, null)) user_id2,
  5        max(decode(rn, 1, username, null)) username1,
  6        max(decode(rn, 2, username, null)) username2,
  7        orgid
  8  from
  9  (select row_number() over (partition by orgid order by orgid) rn,
10         personid, userid, username, orgid from test_otn)
11  group by orgid
12  /
PERSON_ID1 PERSON_ID2   USER_ID1   USER_ID2 USERNAME1            USERNAME2                 ORGID
      1234       2345       1235       2346 TOM                  HARRY                         1
      1111       3333       2222       4444 BOND                 BERY                          2
