Answer 1

After reviewing your code I have to confess I have no idea what you are doing ... or why. Here are some examples:
select ACCOUNTNO
INTO v_accountnumberwhere is v_accountnumber used?
where ACCOUNTNO = p_account
AND rownum < 2;how can this query ever return more than one row?
and finally ... what is this doing that could not be done by the trigger itself or with a MERGE statement?
