My table have duplicate records. I want to impose a primary key on that table. For that I have to replace duplicate values of a column with next value of a sequence.

The requirement is I have a table (TAB1), wherein I have 3 columns, ID, LID and STATUS.
The value in ID column = ID_SEQ.NEXTVAL,and LID will be either 0 or 1 and the possible values for STATUS are 'ED','CP', NULL. The ID column is not suppose to have duplicate values, but there is no check on the table for the same.
Someone has updated the existing data and ID column is containing duplicate values. Wherever LID = 0 and STATUS = NULL and if only if ID is duplicated then the ID_SEQ.NEXTVAL has to be assigned to ID field, so that there are no more duplicate values.
CREATE TABLE tab1 (id NUMBER , lid NUMBER, status VARCHAR2(10));
Existing Data
------------------
INSERT INTO tab1 VALUES (1,0, 'ED');
INSERT INTO tab1 VALUES (1,0, 'CP');
INSERT INTO tab1 VALUES (1,0, NULL);
INSERT INTO tab1 VALUES (1,0, NULL);
INSERT INTO tab1 VALUES (1,0, NULL);
INSERT INTO tab1 VALUES (1,0, NULL);

I am trying to update records in the target table based on the records coming in from source. For instance, if the incoming record is present in the target table I would update them in the target else I would simply insert. I have over one million records in my source while my target has 46 million records. The target table is partitioned based on calendar key. I implement this whole logic using Informatica. Looking at the informatica session log I find that the informatica code is perfectly fine but its in the update part it takes long time (more than 5 days to update one million records). find the TARGET TABLE query and the UPDATE query as below.
TARGET TABLE:
CREATE TABLE OPERATIONS.DENIAL_REGRET_FACT
(
CALENDAR_KEY INTEGER NOT NULL,
DAY_TIME_KEY INTEGER NOT NULL,
SITE_KEY NUMBER NOT NULL,
RESERVATION_AGENT_KEY INTEGER NOT NULL,
LOSS_CODE VARCHAR2(30) NOT NULL,
PROP_ID VARCHAR2(5) NOT NULL,

My aim is to delete duplicates out of above data, with the below condtions.
1) first record with value 30 and then with value 0.
2) if there are 3 duplicate records ex: ID is 1 and Group KK, then i have to delete both 30 & 0 qty records.
3) If there are more than 3 duplicate records ex: ID is 3 and Group is AA, the i have to delete all the records with qty value either 30 or 0 and.
I have written a query like below.
SELECT id,
unit,
RANK ()
OVER (PARTITION BY id, unit
ORDER BY id, unit)
num
FROM temp;
with the above query, i am unable to mark this dynamic duplications.
How can i delete duplicate records from the table.

CREATE TABLE test
(
gidNUMBER(10),
pidNUMBER(10)
);
INSERT INTO test VALUES (10,20);
INSERT INTO test VALUES (20,10);
INSERT INTO test VALUES (25,46);
[code]....
The condition is if GID = PID and PID = GID then only one combination of these records should be retained. For example Out of 10-20 and 20-10 only one record should be retained.
Expected result after deletion

I had created a new table named USERLOG with two fields from a previous VIEW. The table already consist of about 9000 records. The two fields taken from the VIEW, i.e. weblog_views consist of IP (consists of IP address), and WEB_LINK (consists of URL). This is the code I used,
CREATE TABLE USERLOG
AS
SELECT C_IP, WEB_LINK FROM weblog_views;
I want to add another column to this table called the USER_ID, which would consists of a sequence starting with 1 to 9000 records to create a unique id for each existing rows. I'm using Oracle SQL Developer: ODMiner version 3.0.04. I tried using the AUTO-INCREMENT option,
ALTER TABLE USERLOG
ADD USER_ID INT UNSIGNED NOT NULL AUTO_INCREMENT;
But I get an error with this,
Error report:
SQL Error: ORA-01735: invalid ALTER TABLE option

I use a sequence to generate an alphanumeric code and I need to update all rows of a table with that sequence. The sequence is created with this code:
SELECT (CHR(TRUNC(s.nextval/1000) + ASCII('A')) || LTRIM(TO_CHAR(MOD(s.currval,1000),'099'))
FROM dual;
I have tried many things - most recently
Update t3_temp_table
SET mergecode =
SELECT (CHR(TRUNC(s.nextval/1000) + ASCII('A')) || LTRIM(TO_CHAR(MOD(s.currval,1000),'099'))
FROM dual;
I get missing expression error.
It works fine if I use a straight s.nextval

I have experimented with row_number partition but then i just get the sequence returning to 1 when the name value changes.

I have taken all the records in to a cursor. Once after rounding the request of 1st rank and adjusting the values of next rank is done. Trying to round the value for 2nd rank as done for 1st rank. Its not taking the recently updated value(i,e adjusted value in rounding of 1st rank).
This is because of using a cursor having a value which is of old value. Is there any way to handle such scenario's where cursor records gets dynamically updated when a table record is updated.

My duplicate records have been detected by First Name, Last Name, Name, and City.
such as
select FirstName, LastName, Name, City, count(*) as Num of Duplicate from TABLE

It gives the duplicate record. Now I need all the columns and the each duplicate record in the select, so I can see why these records are duplicate.

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.
