I have an oracle trigger that works fine when you manually run it. How can I take the following trigger and make it repeat instead of specifically copying it for each table. For instance..

I have to run this several times for each different 'company'.

accept compnum prompt 'Enter Company Number: '
define logging = "_logging" (CHAR)

create or replace trigger ttfacp100&compnum&logging
before insert on ttfacp100&compnum
for each row
declare
        logname varchar2(8);
begin
                select user into logname from dual;
        :new.t$logn := logname;
end;

/

I want to be able to have a list of companies that run the trigger each time it changes, but only call this script once.
Can something like this be done?

define logging = "_logging" (CHAR)
define compnum = 100
run.trigger()

define compnum = 200
run.trigger()

define compnum = 300
run.trigger()

run.trigger()
{
create or replace trigger ttfacp100&compnum&logging
before insert on ttfacp100&compnum
for each row
declare
        logname varchar2(8);
begin
                select user into logname from dual;
        :new.t$logn := logname;
end;
/
}


Thank you!
