One of easiest ways:
with data as
select 'test123' col from dual union all
select '123test' from dual union all
select 'test' from dual union all
select '123' from dual
select *
from data
where regexp_like(col, '[[:digit:]]+[[:alpha:]]+|[[:alpha:]]+[[:digit:]]+', 'i');
COL    
test123
123test
Just a note - This will fail, if any characters like SPACE (or any non alpha numeric characters) appears in the string like..
with data as
  select 'test 123' col from dual union all
  select '123test' from dual union all
  select 'test' from dual union all
  select '123' from dual
select *
  from data
where regexp_like(col, '[[:digit:]]+[[:alpha:]]+|[[:alpha:]]+[[:digit:]]+', 'i');Edited by: jeneesh on Mar 5, 2013 12:04 PM
You could change like
where regexp_like(col, '[[:digit:]].*?[[:alpha:]]|[[:alpha:]].*?[[:digit:]]', 'i');
