I agree that regexp_replace would be the way to go. You could also combine
translate and replace. For an idea of that:
You translate all the non-numeric to 'z', or spaces. (or null? Since there
will be spaces in the middle).
select data,
[ to_number( ] replace(translate(lower(data), 'abc...xyz','...
Rpad, lpad could come into play. Start with translate function, and work out
from there.

Subject: Remove non-integer Characters from a column
Gurus,
Oracle 11..2.0.3 on Linux R6
==
1) I have a field with a data type of varchar2 that has integers and
non-integer characters.
2) Example: 214' or 61+45 or 88/8.
3) How can i remove the non-integer characters from the table ?
4) Can a function be written to remove non-integer characters ?, so in the
example it would be 214 or 6145 or 888
==
Appreciate any pointers to solve this, thank you in advance.
Sincerely
