I have a table <srabank>

The senario is
We need to select one account number and check the balance after checking the balance if the balance exist we need to transfer to another account .
in the from account the amount need to be reduced and in the to account the amount needed to be added.

for the <accno> <31518746292> the balance is <14000>
after transferring the balance the details will look as follows
<accno><31518746291> <bal> <2000>
<accno><31518746292> <bal> <16000>

Answer Posted / akhil
the below program transfered the amount from one account to another account and generates the reference id and stores that reference id in the database;
in cus_det ac is the primary key
and in tranction table acc is the foreign key
then only reference number will be updated in the tranction table.
create or replace procedure test(acc1 in number,acc2 in number,amt in number) is
acm cus_det.am%type;
i number;
begin
select am into acm from cus_det where ac=acc1;
if acm<amt then
dbms_output.put_line('in sufficient funds');
else
update cus_det set am=am-amt where ac=acc1;
dbms_output.put_line('amount debited from senders account');
dbms_output.put_line('Tranction nnumber for your tranction....make a note of it for future reference');
select round(dbms_random.value(100000,200000)) into i from dual;
dbms_output.put_line(i);
update tranction set t_num=i where acc=acc1;
update cus_det set am=am+amt where ac=acc2;
dbms_output.put_line('amount credited to receivers account');
end if;
end;
