SQL & PL/SQL :: Finding Out If A Table Column Has Special Characters

I have this table column of varchar2 data type. I need to find out if it contains anything other than numbers or alphabets(basically to see if it contains any special characters in it).

I just need to fetch only those rows that has special characters. How do I get this?

CREATE TABLE CHECK_SPL_CHARAC
(ADDRESS VARCHAR2(100));

INSERT INTO CHECK_SPL_CHARAC VALUES ('ABC%ABC');
INSERT INTO CHECK_SPL_CHARACVALUES ('ABC_ABC');
INSERT INTO CHECK_SPL_CHARAC VALUES ('ABC?ABC');
INSERT INTO CHECK_SPL_CHARAC VALUES ('ABC*ABC');
INSERT INTO CHECK_SPL_CHARAC VALUES ('1234');
INSERT INTO CHECK_SPL_CHARAC VALUES ('ABC');
INSERT INTO CHECK_SPL_CHARAC VALUES ('AB C');
INSERT INTO CHECK_SPL_CHARAC VALUES ('12 34');
COMMIT;

I need to get the first 4 rows alone in the sql output. I do not wan to get the last 2 rows with space.
