SQL & PL/SQL :: Duplicate Value In Table
Dec 15, 2010I have a following table,
create table ashok_temp11(col1 varchar2(10),col2 varchar2(10));
and have the following values,
insert into ashok_temp11 values('A1','1001');
insert into ashok_temp11 values('A2','1001');
insert into ashok_temp11 values('A3','1002');
insert into ashok_temp11 values('A4','1003');

I need the duplicate values in the table. That means
col1 col2

Duplicate Database To Another Host
Mar 10, 2013I will be duplicating my production database back to a few weeks ago on my test server, to retrieve certain data. I am running 11g standard edition, not using a recovery catalog.
Below are the basic steps I plan to take in a nutshell.
1. Copy the backup files to the test system
2. In the rman run block (on the test server)
A. Set newname for each of the datafiles and tempfiles (don't have many files)
B. Duplicate command to point in time, specifying backup location and no filename check.
3. Export the data

Removing Duplicate Keys
Jul 3, 2008Trying to delete duplicate rows from a table. The problem is, they aren't exactly duplicate rows. Let me explain.
I am migrating data from a Oracle 8.1.7 db to a 10.2.1 db. In the older db, this certain table does not have a PK/Unique Index, but in the new db there is a unique index. The fields that the index is unique on are:
SUBSCR_NO, SUBSCR_NO_RESETS, EXTERNAL_ID, EXTERNAL_ID_TYPE, ACTIVE_DATE.
In the old db, when I run this query I get 1229 rows. With a count of 2 each.
select SUBSCR_NO, SUBSCR_NO_RESETS, EXTERNAL_ID, EXTERNAL_ID_TYPE, ACTIVE_DATE, count(*)
from customer_id_equip_map
group by SUBSCR_NO, SUBSCR_NO_RESETS, EXTERNAL_ID, EXTERNAL_ID_TYPE, ACTIVE_DATE
having count(*)>1;
They are duplicates on those fields, but they are not totally duplicate rows because there is a field called is_current that has 0 in one row and has 1 in the other. What I need to do, is delete the 1229 rows with is_current=0.

PL/SQL :: Duplicate Rows Removal
Jul 3, 2012removing duplicate rows from a table.
We have the following table:
SSD@ermd> desc person_pos_history
Name Null? Type
------------------------------------------------------------------------ -------- ------------------------
PERSON_POSITION_HISTORY_ID NOT NULL NUMBER(10)
POSITION_TYPE_ID NOT NULL NUMBER(10)
PERSON_ID NOT NULL NUMBER(10)
EVENT_ID NOT NULL NUMBER(10)
USER_INFO_ID NUMBER(10)
TIMESTAMP NOT NULL DATE
We found out that few person_id's are repeating for a particular event (3):
select PERSON_ID, count(*)
from person_pos_history
group by PERSON_ID, EVENT_ID
having event_id=3
and count(*) > 1
order by 2
PERSON_ID COUNT(*)
---------- ----------
217045 356
216993 356
226198 356
217248 364
[Code]...
If we look at the 1st person id "217045", we can see that it is repeating 356 times for event id 3.
SSD@ermd> select POSITION_ASSIGNMENT_HISTORY_ID, POSITION_TYPE_ID, PERSON_ID,EVENT_ID, to_char(timestamp, 'YYYY-MM-DD HH24:MI:SS')
2 from person_pos_history
3 where EVENT_ID=3
4 and person_id=217045
5 order by timestamp;
PERSON_POSITION_HISTORY_ID POSITION_TYPE_ID PERSON_ID EVENT_ID TO_CHAR(TIMESTAMP,'
------------------------------ ---------------- ---------- ---------- -------------------
222775 38 217045 03 2012-05-07 10:29:49
222774 18 217045 03 2012-05-07 10:29:49
222773 8 217045 03 2012-05-07 10:29:49
[Code]...
356 rows selected.It is safe to assume that the person id/event id with the earliest timestamp is the one that was loaded 1st, hence, the one we want to keep and the rest should be deleted.

SQL & PL/SQL :: Updating A Duplicate Primary Key

I have a dilemma......the constraint was disable somehow in my table of about 900,000 records which allowed the insertion on duplicate primary keys as well as duplicate records. I've managed to get rid of the duplicate records, but I haven't quite figured out how to update the primary key and version number. I've tried the following but
UPDATE TABLE
SET PM_PM_KEY=(MAX(PM_KEY)+1), PM_VERNO=(MAX(PM_VERNO)+1)
WHERE TBLDATE= MAX(TBLDATE)
ORDER BY TBLDATE ASC
GROUP BY PCN;
The query is failing with

Sep 23, 2010I have a table with multiple columns and I need to retrieve the ones where column a stores duplications for records where column b is discrepant
this is the table
NAME_ID PHONE_NUMBER
12345 +41 22 595 5555
12345 +41 22 595 5555
12342 +41 22 595 5500
12340 +41 22 595 5555
the query should return
NAME_ID PHONE_NUMBER
12345 +41 22 595 5555
12340 +41 22 595 5555
The closest I got was with the below, but this also returns duplicates within the same NAME_ID.
select phone_number, name_id
from name_phone
where (phone_number) in
(select phone_number
from name_phone
group by phone_number
having count(*) > 1)
group by phone_number, name_id
order by phone_number

like this am having multiple times the duplicates.
I have written the below query to delete the duplicate records. But it is deleting only one record (if we have 5 duplicates it is deleting only 1 ). But I am looking to delete if we have 5 duplicates need to delete 4 duplicates and keep 1 record in the table.
query which am using to delete the duplicates is
DELETE FROM Table1 a
WHERE ROWID IN (SELECT MAX(ROWID)
FROM Table2 b
WHERE a.ID = b.ID);
it is deleting only one row but I want to delete 4 records out of 5 and keep one record.

2. Do I need to make separate executions for both the nodes of the cluster?

what to need to do to avoid this duplication? Is it something wrong with Oracle Listener.ora as it have two listeners (ABC and ABC1) that might be causing duplication?
