Hi,
Sorry, I'm not getting you. For entering dates you don't have to enter / is you put the appropiate mask.
Example:
Connected to Oracle Database 10g Express Edition Release 10.2.0.1.0
Connected as hr
SQL> create table test_date(col date);
Table created
SQL> insert into test_date values(to_date('01032009', 'DDMMYYYY'));
1 row inserted
SQL> COMMIT;
Commit complete
SQL> select * from test_date;
COL
01/03/2009
