For every record which came yeterday in table ABC, I need to find if same record data does exists in historical records of the same table, and if match is find, I need to display all the occurrences.
For example Data got inserted yesterday as
SQL RES : Col 1= "A" Col 2: "B" Col 3: "C" Date = Sysdate -1
then, I need to scan through Query results from the history where I can find if there exists same combination already.and if so I need to display both i.e Record form yesterday and from history.
Here is the one I am using to get the base data.
with base as(
select Col 1, Col 2, Col 3,A.Create_DT
from A,B
where A.ID = B.ID
)

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
GROUP BY FirstName, LastName, Name, City
having count (*) > 1
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.

I have a table and it's having duplicate records.
for one particular employee, he is having multiple records with the same data in the table
EMPNO ENAME JOB SAL DOB
-------------------------------------------------------
1 A X 100 1956
2 B Y 200 1974
1 A X 100 1956
3 C Z 300 1920
[Code]....
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.

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);
[code]....
get the result using a single update statement.

I have a query which pulls data from emp view
select am_obj_emp_obj(empno,ename,sal,deptno,service) from
(select empno,ename,sal,deptno ,service from emp_vw where 1=1 and rownum < 2000 and service in ('MAN','SACH','SACL','KACL'))
WHERE SAL = (SELECT MAX(SAL) FROM EMPS_VW WHERE DEPTNO = deptno or sal is null)
union all
[code]...
This query is pulling 12 records of which 6 records are coming from the first query and the same 6 records is coming from the second query after union all Here am_obj_emp_obj is the object type and emp_vw is the view
Now I wanted to remove the duplicate records.When I implement the union operater it is giving me error.
ORA-22950: cannot ORDER objects without MAP or ORDER method.

How can I delete the duplicate combination of records from the below 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
GID PID
---------- ----------
10 20
25 46
89 64
15 16

I've got a table with XML code (CLOB column) and I need to read and write every of parameter(blue marked below) and value (red marked below) record from that.
For example:
create table tmp_mape
(msisdn varchar2(100),
xml_params CLOB )
insert into tmp_mape values
('423903200200',
'<parameters xmlns="http://datalan.sk/webreporting/params/v1_0"><parameter name="id"><value>410</value></parameter><parameter name="isDropped"><value>true</value></parameter></parameters>' );
[code]........
I tried to read this every values of xml code by select below:
select
extractValue(value(x),'/parameter/@name', 'xmlns="http://datalan.sk/webreporting/params/v1_0"') b,
extractValue(value(x),'/parameter/value', 'xmlns="http://datalan.sk/webreporting/params/v1_0"') a,
a.*
[code]......
This select returns a duplicate records because of more the one parameter and value records from XML column.

I have the following situation and need support:
create table try_x
(a number PRIMARY KEY,
b NUMBER,
c NUMBER,
f_text VARCHAR2(10));
insert ALL
into try_x values (0,1,1,'abc')
into try_x values (1,1,1,'abc')
into try_x values (2,1,1,'xyz')
into try_x values (3,1,2,'abc')
into try_x values (4,1,2,'abc')
into try_x values (5,1,2,'abc')
into try_x values (6,1,3,'abc')
into try_x values (7,1,3,'abc1')
into try_x values (8,1,3,'abc2')
into try_x values (9,1,3,'abc2')
select * from DUAL;
Although a is the PK, records with similar b,c,f_text are considered redundant and I need to delete all occurrences in the table where b, c, d are redundant and leave the unique ones. So I need the result to look like:
a b c f_text
-----------------
0 1 1 abc
2 1 1 xyz
3 1 2 abc
6 1 3 abc
7 1 3 abc1
8 1 3 abc2

I'm calling sql loader recursively to load data from CSV files which has thousands of records in each file. If there are any duplicate records, the sql loader terminates with ORA00001. My query is how to ignore inserting duplicate records and continue with the load.
Most of the posts in forums suggests to use skip command. But i do not think that is a wise option in my case as we cannot predict the maximum error count. more over I have set up ERROR=0 in my code so that the code terminates in case thers is a data error.
any other way to ignore inserting duplicate records into the tables.
