SQL & PL/SQL :: Oracle 9i / 10g - Remove Duplicate Records?
Nov 11, 2010
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.

I want to remove matching dbid's from the rman catalog without compromising te integrity of the catalog. I do however know a single way of removing them and its using the dbid and db_key which in my case are not not unique. The funny thing is they've running normally for a year now.

Database version: 11.2.0.3.0
I need to remove duplicate values from concatenated long string of state codes(comma separated). Ex: 'VA,VA,PA,PA,CT,NJ,CT,VA'. I tried following query and did not get required out put.
select regexp_replace('VA,VA,PA,PA,CT,NJ,CT,VA,CT,PA,VA,CT','([^,]*)(,1)+($|,)', '13') new_str from dual;
Define Meta-character's format in regular expression to get desired result. Out put required: VA,PA,CT,NJ (with out any duplicates).

I am facing below error while doing Schema refresh from production to development. I am facing this error in development database.
IMP-00003: ORACLE error 2264 encountered
ORA-02264: name already used by an existing constraint
IMP-00017: following statement failed with ORACLE error 2264:
"ALTER TABLE "TASKS" ADD CONSTRAINT "VALUE_CK" CHECK (wrkt_k"
"ow <> 'S') ENABLE NOVALIDATE"
i guess "need to Remove the orphaned child records from the child table (foreign key relationship), and then re-execute the ALTER TABLE ENABLE CONSTRAINT command."
how to find orphaned child records from child table ?
how to resolve this error?

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.

EMPNO ENAME JOB SAL DOB
-------------------------------------------------------
1 A X 100 1956
2 B Y 200 1974

[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.

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'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.
