DB2 DIGIT FUNCTION IN ORACLE

What is the DB2 DIGIT FUNCTION equivalent in ORACLE database. We have done a migration from db2 to oracle and many programs just fails where I encounters digit function. Is there any workaroud or function present in oracle database which makes the program working.

Answer 1

Addendum ...
OK I found what the DIGIT function does.
I am not sure if there is a function in Oracle that maps directly to DIGIT function in DB2
but you can do something like this:
select lpad(replace(to_char(abs(n)),'.'),
(select to_number(data_precision) from user_tab_columns where table_name = 'A' and column_name = 'N'),'0')
from a
In the SQL above n is the column in table A. Data_precision column gets the size of the column.
Option 2:
You could write your own function in Oracle to do what the SQL above does
create or replace function digit (col_val in number, col_name IN varchar2, tab_name IN varchar2) return varchar2
as
v_val varchar2(100);
v_prec number;
begin
select to_number(data_precision) into v_prec from user_tab_columns where table_name = upper(tab_name) and column_name = upper(col_name);
v_val := lpad(replace(to_char(abs(col_val)),'.'),v_prec,'0');
return v_val;
end;
Then use the function as follows:
select digit(n,'N','A') from a
