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'm trying to group sets of data based on time separations between records and then count how many records are in each group.
In the example below, I want to return the count for each group of data, so Group 1=5, Group 2=5 and Group 3=5
SELECT AREA_ID AS "AREA ID",
LOC_ID AS "LOCATION ID",
TEST_DATE AS "DATE",
TEST_TIME AS "TIME"
FROM MON_TEST_MASTER
WHERE AREA_ID =89
AND LOC_ID ='3015'
AND TEST_DATE ='10/19/1994';
[code]....
Group 1 = 8:00:22 to 8:41:22
Group 2 = 11:35:47 to 11:35:47
Group 3 = 15:13:46 to 15:13:46
Keep in mind the times will always change, and sometime go over the one hour mark, but no group will have more then a one hour separation between records.
i am using this query to see only duplicate records but not able to get through
select * from
emp
where rowid NOT IN
( select max(rowid) from emp GROUP BY job_id)
i have table with name, count, flag with dublicate records
example
with swayam name , counts are 3, 4
with ramana name, counts are 5,5
with reddy name, counts are 1,2,3
i want to update the flag
if count are same then update one of record (flag='A') and other should be flag='R'
if count are different then update the max count (flag='A') and other should be reject remaing (flag='R'). use below quires
CREATE TABLE TEST_DUB ( NAME VARCHAR2(99), V_COUNT NUMBER, FLAG VARCHAR2(1));
Insert into TEST_DUB (NAME, V_COUNT)
Values
('SWAYAM', 3);
Insert into TEST_DUB

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

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.
say I have duplicate records in TABLE3, can I use following SQL to delete the duplicates?FYI, BUS_FID is unique number column.

COL2 VARCHAR2(10 BYTE),
COL3 VARCHAR2(10 BYTE),
COL4 NUMBER

Insert into TEMP_TEST

[code]....
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.

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.

I have one table employee where there are 4 fields ,emp_code,emp_locn,emp_job_code,emp_job_desc the problem is i am trying to prepare a group reports based on location and emp_job_code there is a duplication of data in the emp_job_desc ,
For example there is a job_code E2 Which has two different job_descriptions for two different employees like E2-PAINTER-SPRAY, E2- PAINTER -SPRAY, another example is E1-rigger , E2-RIGGER and so on.Is there a method to match them together as one description.
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 (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

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

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>' );

extractValue(value(x),'/parameter/value', 'xmlns="http://datalan.sk/webreporting/params/v1_0"') a,

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.
when i run report in PDF, RTF or HTML then correct numbers of records appear but when i run same report in excel then it bring extra records (duplicate).

If i remove rownum, it gives the correct output. Why can't rownum be used here ?
