I did google a bit and tried:

/select * from TABLE where first_name not like '%[a-z0-9]%'; /

you'll probably have to use a regex for that.

something like... (my regex is really rusty)

... WHERE first_name !~ '^[a-z0-9]*$';

Something like:

... WHERE first_name ~ '[^\w]'

might do the trick.

well, at least one of those has a space inline, you didn't say that was
acceptable, just a-z0-9
and of course, upper and lower case, so you probably should use
[A-Za-z0-9 ] (note the space before the close bracket)

Sorry guys I should have mention spaces, I did but it was a bit late. Anyway that [A-Za-z0-9 ] worked thanks John.
