SQL> INSERT INTO t VALUES ('A', 1) 2 / 1 row created. SQL> INSERT INTO t VALUES ('B', 2) 2 / 1 row created. SQL> SELECT * FROM t 2 / this%is,so This@#is^~even+&cooler ---------- ---------------------- A 1 B 2 </pre> If you still want to remove these special characters, two SQL functions may come in handy: <a href="http://download-west.oracle.com/docs/cd/B19306_01/server.102/b14200/functions196.htm" rel="nofollow">TRANSLATE</a> and <a href="http://download-west.oracle.com/docs/cd/B19306_01/server.102/b14200/functions134.htm" rel="nofollow">REPLACE</a>. You do not need to filter out special characters as long as you wrap your column names with qutation marks:

SQL> CREATE TABLE t
  2  ("this%is,so-,cool$,man()" VARCHAR2(10),
  3  "This@#is^~even+&cooler" NUMBER)
  4  /

Table created.

SQL> INSERT INTO t VALUES ('A', 1)
  2  /

1 row created.

SQL> INSERT INTO t VALUES ('B', 2)
  2  /

1 row created.

SQL> SELECT * FROM t
  2  /

this%is,so This@#is^~even+&cooler
---------- ----------------------
A                               1
B                               2

If you still want to remove these special characters, two SQL functions may come in handy: TRANSLATE and REPLACE.
