partitioned tables

Folks,
I need to do the following:

Have a table that has 92 partitions. They are named as part001, part002..... part092.

Want to do insert into the partition directly. The partition i want to insert into will be called based on the value of a parameter i send in to the stored procedure.
A simple way is to use IF..THEN ..ELSE... but for 92 times its a little too repetitious.

ie., if value = 1 then
insert into emp partition (part001).....
elsif value = 2 then
insert into emp partition (part002)....
elsif.....
....

Can I build my insert string dynamically? ie.,

create or replace procedure doinsert as
i varchar2;
v_part varchar2;

So, if VALUE = 2, then

if length(value) = 1 then
i = '00' || to_char(VALUE)
elsif length(calue) = 2 then
i = '0' || to_char(VALUE)
elsif length(value) = 3 then
i = to_char(VALUE)
end if;

v_part = 'part' || i
Insert into partition v_part ... ..........
...
...
end;
/


The above doesn't seem to work. Any suggestions please....

Thanks,
Aruna

Declare
vTable Varchar2 (10);
Begin
vTable := 'part' || LPAD (value, 3, '0');
Insert into partition vTable...
End;
