how to delete duplicated records from a table without using row_id. I found the duplicated rows from a table using Analytical Function. But i could not use the Analytical function in the where condition.
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 (NAME, V_COUNT) Values
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);
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 to display the data which is shown below without duplicate records in compid and compname and all policy_id's should be there while excuting this query iam getting this data.
select distinct comp_id as compid, comp_disp_name as company, plcy_id as policyid,

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.
I have two identical tables with same structure and have some duplicates between those two. Finally I want to combine togather and in a single table and knockout the duplicates.
SQL how can we do this in a simple way? each tables has around millions records.
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.
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.
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.
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).
I'm trying to Rank Username based on the Total Sum of amount waived but I want to avoid Ranking the Overall Total at the bottom, plus I dont want them in Ranking order, I want the order to stay the same as it currently is.
SELECT DECODE(GROUPING(USERNAME),1,'TOTAL',0,UPPER(USERNAME)) as "USERNAME", SUM(CASE WHEN TO_CHAR(DATE_PROCESSED,'MON') = 'JAN' THEN AMOUNT_WAIVED ELSE 0 END) AS JAN, SUM(CASE WHEN TO_CHAR(DATE_PROCESSED,'MON') = 'FEB' THEN AMOUNT_WAIVED ELSE 0 END) AS FEB,
I want to do group ranking in desired col3 in such a way that it checks for different values across consecutive rows under col2 and assigns a number to each group. Just when two consecutive rows in col2 have same value then the group ends and the next group starts.
So my desired output is:
Col1 Col2 Col3 1 A 1 2 B 1 3 C 1 4 D 1 5 D 2 6 A 2
[code]...
Here you can see that the first four rows under col2 are unique i.e A,B,C,D so col3 assigns this as group number 1. It ends at row 4 becuase row 5 also has value D under column 2. So in other words, each group must have all unique values and there should not be any repetition. For example, see group 3 (under col3) in above desired output; it starts from row 9 and ends at row 11 because row 12 also has value 'C' and the value 'C' has already occurred in group 3 in row 9.
I want to achieve this SQL. I tried using Dense rank but couldn't go through. I want the shortest possible query to acheive this.
I have a query find window that allows you to search on various attributes.Also i have a radio button within the query find that allows you to filter the results either as a single record or mulitiple records For example consider the data below.....
I have a View that joins the 2 tables together so for Record_Id = 1 the view returns 3 rows
I would like to have a query find window that allows you to search using: Record_No Line_Desc
and has a radio button to allow you to either show the records as a single line or as all detail lines Therefore i would like the following selections:
1) Enter no search criteria but select Single radio option will return 1 record with default line description of Line1 2) Enter no search criteria but select Multiple radio option will return all 3 records 3) Enter Line_Desc = Line1 with Single radio option brings back one record with Line_Desc = Line1 4) Enter Line_Desc = Line2 with Single radio option brings back one record with Line_Desc = Line2 5) Enter Line_Desc = Line3 with Single radio option brings back one record with Line_Desc = Line3 6) Enter Line_Desc = Line1 with Multi radio option brings back one record with Line_Desc = Line1 7) Enter Line_Desc = Line2 with Multi radio option brings back one record with Line_Desc = Line2 7) Enter Line_Desc = Line3 with Multi radio option brings back one record with Line_Desc = Line3
I need the form to select from the view but then perform a rank after it has selected the relavant data. Then the radio button would use the ranking to select either one record or multi records.
INSERT INTO T VALUES (1,'JAMES'); INSERT INTO T VALUES (1,'DOLLY'); INSERT INTO T VALUES (2,'MICHEAL'); INSERT INTO T VALUES (2,'FLASH'); INSERT INTO T VALUES (3,'JAMES'); INSERT INTO T VALUES (3,'MARY'); INSERT INTO T VALUES (4,'JAMES'); INSERT INTO T VALUES (4,'DOLLY'); INSERT INTO T VALUES (5,'JAMES'); INSERT INTO T VALUES (5,'DOLLY'); INSERT INTO T VALUES (6,'JAMES'); INSERT INTO T VALUES (6,'MARY');
SELECT * FROM T ORDER BY 1
ID NAME 1 JAMES 1 DOLLY 2 MICHEAL 2 FLASH 3 JAMES 3 MARY 4 JAMES 4 DOLLY 5 JAMES 5 DOLLY 6 JAMES 6 MARY
each 'ID' has two values always. I want to rank the data based on same pair 'name' in an 'ID'
for example, my desired output is:
ID NAME RANK 1 JAMES 1 1 DOLLY 1 2 MICHEAL 1 2 FLASH 1 3 JAMES 1 3 MARY 1 4 JAMES 2 ---> THAT IS RANK 2 BECAUSE THIS IS THE 2ND TIME JAMES AND DOLLY ARE IN THE SAME 'ID' 4 DOLLY 2 -----> SAME AS ABOVE 5 JAMES 3 ---> THAT IS RANK 2 BECAUSE THIS IS THE 3RD TIME JAMES AND DOLLY ARE IN THE SAME 'ID' 5 DOLLY 3 -----> SAME AS ABOVE 6 JAMES 2 ---> THAT IS RANK 2 BECAUSE THIS IS THE 2ND TIME JAMES AND MARY ARE IN THE SAME 'ID' 6 MARY 2 -----> SAME AS ABOVE
I'm looking for a script to partition the data into sections where the VALUE is the same over a constant period of time with no breaks. I'd like to give each partition a value to identify it by.
So the outcome of the script would be the following -
I was trying to do something with trunc(date_time) but that didnt work out right as the blocks of data can carry over several days as seen in the rows with IDENTIFIER = 8.
