Non Numeric Data query

Question

Hi,
I'm trying to check our HR phone number table for phone numbers which contain anything except numbers and spaces.
Using sample data:
WITH sampledata AS
     (SELECT '01234 123456' col FROM DUAL UNION ALL
      SELECT '01234 123456 (Ext 456)' FROM DUAL UNION ALL
      SELECT '01234 123213234 (** 2342)' FROM DUAL)
SELECT *
  FROM sampledata;I'd like to use SQL to find the 2nd and 3rd examples (and any other rows where the telno does NOT contain just numbers and spaces).
I've tried:
adding a WHERE:
WHERE NOT REGEXP_INSTR(col,'[0-9]') > 0Or this:
where regexp_like(col, '[^[0-9]]*')But when I try that, all rows are returned, presumably because all rows contain numbers.
I'm not sure how to change to return lines which contain both numeric and alphanumeric data, but where spaces are ignored (i.e. if row1 in e.g. above is okay, rows 2 and 3 aren't).
Any advice much appreciated.
Thanks
