Case issue in Database table

Question

Hi All,
We have an issue of lowercase in database table and we want to convert that lowercase data to upper case. The code for doing this operation is as follows:
SELECT * FROM zehs_volumes INTO TABLE i_volumes_temp.
LOOP AT i_volumes_temp.
DELETE zehs_volumes FROM i_volumes_temp.
IF sy-subrc is INITIAL.
  COMMIT WORK.
ELSE.
  ROLLBACK WORK.
ENDIF.
TRANSLATE i_volumes_temp-zehs_business TO UPPER CASE.
MODIFY i_volumes_temp.
CLEAR i_volumes_temp.
ENDLOOP.
SORT i_volumes_temp BY SUBID ZEHS_BUSINESS ZEHS_SITE ZEHS_ROLE
                       ZST_DATE ZED_DATE.
DELETE ADJACENT DUPLICATES
FROM i_volumes_temp COMPARING SUBID ZEHS_BUSINESS ZEHS_SITE
                              ZEHS_ROLE ZST_DATE ZED_DATE.
MODIFY zehs_volumes FROM TABLE i_volumes_temp.
IF sy-subrc is INITIAL.
  COMMIT WORK.
ELSE.
  ROLLBACK WORK.
ENDIF.
The problem wid the above code is that it first clears the entire database table and then fills it with the modified data from the internal table. But we do not want to take risk of emptying the database table. Is there any way out to perform the above operation?
Thanks in advance

Hi Karthik,
Thanks for replying.
In our case the scenario is we need to delete wrong entires in the database table based on the primary input fields. There is already a utility to do so. But in the table some of the entries are present in the lower case.
For eg. Suppose we need to delete entry with field zehs_business = "Pioneer". When we input this SAP interpret it as PIONEER and we get an error message "No data exist".
So the code should we in such a way that all the value in field zehs_business should be translated to upper case otherwise SAP will give an error message of non-existence of data.
The code which you gave adds one more entry in database table with zehs_business = "PIONEER". Now the database table have two records one with "Pioneer" and other with "PIONEER". After the execution of DELETE statement only the record with zehs_business = PIONEER gets deleted....and the other record still exist.
Is there any way to avoid above situation....
