Need an anonymous block for fake update,

Question

I have a table called sk_a
create table sk_a (a number, b date, c varchar2(10));
and an audit table
create sk_a_audit (audit_id number, a number, b date, c varchar2(10),dml_action varchar2(4));
and sequence sk_a_audit_seq
create sequence sk_a_audit_seq
when any insert or update happens into sk_a table, respective data should insert into sk_a_audit table
and trigger is
CREATE OR REPLACE TRIGGER SK_A_TRG
AFTER INSERT OR UPDATE
ON SK_A
FOR EACH ROW
DECLARE
l_code NUMBER;
l_errm VARCHAR2 (64);
BEGIN
IF (INSERTING OR UPDATING)
THEN
INSERT INTO SK_A_audit
VALUES (sk_a_audit_seq.NEXTVAL, :NEW.a,
:NEW.B, :NEW.C ,'I');
END IF;
EXCEPTION
WHEN OTHERS
THEN
l_code := SQLCODE;
l_errm := SUBSTR (SQLERRM, 1, 64);
DBMS_OUTPUT.put_line ('DML Operation is failed ' || l_code || l_errm);
END;
sk_a may or maynot have primary or unique keys,
now my requirement is
audit table will be deleted by business users,,
and then I have to run an update on sk_a table (fake update) so that data will come and insert into audit table,,,,
so that audit table will be back with all the data of sk_a table again,
I need an anonymous block for this, can any one help on this,

if u know that users going to delete the audit table, then take the back of the table. that is better instead of fake update.
U can use exp utility for taking that back up
