Try this:
CREATE FUNCTION to_dec
( p_str in varchar2,
p_from_base in number default 16 ) return number
AS
l_num number default 0;
-- l_hex varchar2(16) default '0123456789ABCDEF';
l_base varchar2(16) default '0123456789ABCDEF....YZ'; -- fill
in the blanks
begin
for i in 1 .. length(p_str) loop
l_num := l_num * p_from_base +
instr(l_base,upper(substr(p_str,i,1)))-1;
end loop;
return l_num;
end
/
HTH, don't forget to fill in l_base local variable. Obviosly, in your case
"p_from_base" parameter will be 36.
