Error while deleting Records using ROWID

Question

Hi all
I have a small PL/SQL Block which accepts the Table Name as the User Input and
deletes duplicate records from that table using ROWID.
SET SERVEROUTPUT ON
SET VERIFY OFF
PROMPT Script to Delete Duplicate Records from a Table using ROWID
ACCEPT TAB_NAME PROMPT 'Enter the Table Name : '
DECLARE
v_tab_name VARCHAR2(50):='&TAB_NAME';
BEGIN
EXECUTE IMMEDIATE 'DELETE FROM v_tab_name AA WHERE AA.ROWID <> (SELECT MIN(B.ROWID) FROM v_tab_name B WHERE AA.ID=B.ID)';
DBMS_OUTPUT.PUT_LINE('Duplicate Records Deleted');
END;
When i execute this query it errors out saying table or view does not exist.
Anybody's help is kindly appreciated.
Regards
Nakul.V

Dear Nakul.V!
Please change your execute immediate statement as follows:
EXECUTE IMMEDIATE 'DELETE FROM ' || v_tab_name || ' AA
                   WHERE AA.ROWID IN (SELECT MIN(B.ROWID)
                                      FROM' || v_tab_name || ' B
                                      WHERE AA.ID=B.ID)';Yours sincerely
