Answer 1

This will work in 10g (and 9i I think)...
with t as (
select 1234528215 as n from dual union all
select 444 as n from dual union all
select 374619286 as n from dual
, digits as (
select level-1 as d from dual connect by level <= 10
select n, d, length(n)-nvl(length(replace(n,d)),0) as occurences
from digits, t
where length(n)-nvl(length(replace(n,d)),0)>0
order by n,d
N                      D                      OCCURENCES            
444                    4                      3                     
374619286              1                      1                     
374619286              2                      1                     
374619286              3                      1                     
374619286              4                      1                     
374619286              6                      2                     
374619286              7                      1                     
374619286              8                      1                     
374619286              9                      1                     
1234528215             1                      2                     
1234528215             2                      3                     
1234528215             3                      1                     
1234528215             4                      1                     
1234528215             5                      2                     
1234528215             8                      1                      As Charles and Frank said, you can use REGEXP_COUNT in 11g.
