How to delete duplicate records in all tables of the database

I would like to be able to delete all duplicate records in all the tables of the database. Many of the tables have LONG columns.
Thanks.

Hello
To delete duplicates from an individual table you can use a construct like:
DELETE FROM
    table_a del_tab
WHERE
    del_tab.ROWID <> (SELECT
                            MAX(dups_tab.ROWID)
                      FROM
                            table_a dups_tab
                      WHERE
                            dups_tab.col1 = del_tab.col1
                      AND
                            dups_tab.col2 = del_tab.col2
                      )You can then apply this to any table you want. The only differences will be the columns that you join on in the sub query. If you want to look for duplicated data in the long columns themselves, I'm pretty sure you're going to need to do some PL/SQL coding or maybe convert them to blobs or something.

How to delete Duplicate records from the informatica target using mapping?

Hi, I have a scenario like below: In my mapping I have a source, which may containg unique records or duplicate records. Source and target are different tables. I have a target in my mapping which contains duplicate records. Using Mapping I have to delete the duplicate records in the target table. Target table does not contain any surrogate key. We can use target table as a look up table, but target table cannot be used as source in the mapping. We cannot use post SQL.

How to delete Duplicate records in IT2006

Dear Experts
We have a situation like where we have duplicate records with same start and end dates in IT2006. This is because of the incorrect configuration which we have corrected now, but we need to do a clean-up for the existing duplicate records. Any idea on how to clean it? I ran report RPTKOK00 to find these duplicates but I could not delete the duplicate/inconsistenct record using report RPTBPC10 or HNZUPTC0, i Could only delete the deductions happened in the record.
Is there any standard report/any other means of deleting the duplicate records created in IT2006?
Thanks in advance for all your help.
Regards
Vignesh.

You could probably use se16n to identify the duplicates and create the list of quotas to delete, and you could probably use t-code lsmw to write up a script to delete them, but be aware that you can't delete a Quota if it's been deducted from.
You'd have to delete the Absence/Attendance first, then delete the Quota, then recreate the Absence/Attendance.

How to delete duplicate records in cube

Hi,
can u help me how to delete the duplicate records in my cube
and tell me some predifined cubes and data sourcess for MM and SD modules

Hi Anne,
about "duplicate records" could you be more precise?.
The must be at least one different Characteristic to distinguish one record from the other (at least Request ID). In order to delete Data from InfoCubes (selectively) use ABAP Report RSDRD_DELETE_FACTS (be carefull it does not request any confirmation as in RSA1 ...).
About MM and SD Cubes see RSA1 -> Business Content -> InfoProvider by InfoAreas. See also for MetadataRepository about the same InfoProviders.
About DataSources just execute TCode LBWE in you source sys: there you see all LO-Cockipt Extrators.
Hope it helps (and if so remember reward points)

How to delete duplicate entries in table for the object DNL_CUST_BASIS2

In the SMQ2 the status is SYSFAIL.
I checked in the ST22 for dumps.It says about the error while accessing the table T006.
While analysing this,i found some duplicate entries in the related tables of this object.
Can somebody help me how to delete these duplicate entries?
Thanks,
Senthil.

Delete them directly from the table using se16:
select the entries in the classic view (not ALV or grid view).
activate the debugger.
press the view button. --> you'll enter in the debugger
press F7
locate the sy-ucomm variable & change it to "DELE".
press F8
delete the entries.
Trick-shots
but it works!

How to delete duplicate record in Query report

Hi Experts,
I had created an infoset and query in my sap, but I want to delete some duplicate records before the list out put.Please can we add some further codes in the Extras code to delete duplicates? And how do it? Would you please give me a simple brief.
Joe

Hi,
You can try to restrict in the filter area in query designer with the values for characteristic which gives correct
result.
But still i would suggest that in the cube you keep not the duplicate records as this is not your requirement and giving
you wrong result.
So you can reload the correct records in the cube inorder to avoid such problems even in future.

Hi Naren,
First get the index number of the IT_data table and store it in one variable whose declaration like this.
data: tabix type sy-tabix.
while reading the internal table it_data set the tabix variable.
tabix = sy-tabix.
Instead of the above use below one.
Delete it_data-objek
Use the Below statement it will delete the row from the internal table.
Delete it_data-objek index tabix
Thanks,
Chidanand

How to delete a record from BSEG table

Dear Experts,
How to delete a record from BSEG table.
If there possible to delete some records from transparent table ?
Please help.
Regards,
Tan

Hi,
Deleting a record from a standard table can be done only if table maintenance exists - Cehck tcode - SM30. But it is not advisable to delete records, coz the records may be dependent on many other tables. If u delete in a single place, there may be chance that inconsistency in the data happens and hence will affect ur financial statements.
Pls. assign points, if useful

How to avoid Duplicate Records while joining two tables

Hi,
I am trying to join three tables, basically two tables are same one is like history table, so I wrote a query like
select
e.id,
e.seqNo,
e.name,
d.resDate,
d.details
from employees e,
((select * from dept)union(select * from dept_hist)) d
join on d.id=e.id and e.seqno=d.seqno
but this returing duplicate records.
Could anyone please tell me how to avoid duplicate records of this query.

Actually it is like if the record is processed it will be moved to hist table, so both table will not have same records and I need the record from both the tables so i have done the union of both the tables, so d will have the union of both records.
But I am getting duplicate records if even I am distinct.
