sql - Finding the count of characters and numbers in a string

Hi I have a table test as below

NAME
---------
abc1234
XYZ12789
a12X8b78Y9c5Z

I try to find out the count of number of numbers and characters in the string as

select name,length(replace(translate(lower(name),'abcdefghijklmnopqrstuvwxyz',' '),'      ','')) as num_count,
length(replace(translate(name,'1234567890',' '),' ','')) as char_count
from test6;

Its executing fine giving the output

NAME    NUM_COUNT   CHAR_COUNT
abc1234         4       3
XYZ12789        5       3
a12X8b78Y9c5Z   7       6

But my question is there any option by not giving the abcdefghijklmnopqrstuvwxyz and 1234567890 manually

@alfasin answer is good, but if you're using 11g then it can get simpler:

select name,
REGEXP_count(name,'d') as num_count,
REGEXP_count(name,'[a-zA-Z]') as char_count,
from test6;
