Please suggest solution for deletion of all rows in table at a time

Question

Suggest me pl/sql code for a push button in form to ‘delete entire rows’ in a table.
BEGIN
LOOP
DELETE
FROM mytable(say table name)
WHERE ROWNUM < 20000;
EXIT WHEN SQL%ROWCOUNT = 0;
COMMIT;
END LOOP;
END;
I wrote this code but not deleted .
Execute immediate ‘truncate table <tablename>’; this code too not working.
What my need is ‘ I don’t want to put entire block fields in the form, just I want to put a push button and when I pressed it must delete all rows in a particular table.
That I want to delete all rows form builder runtime not by entering sql.8.0 and then there delete the rows.
thanks in advance

to delete all records in a table, if you want to get good performance, then use:
FORMS_DDL('TRUNCATE TABLE your_table_name');
It is better than use DELETE FROM TABLE_NAME. But if you have condition in where clause, then you have to use DELETE FROM ...
