SQL> desc t2;
Name Null? Type
----------------------------------------- -------- -------------

C1 VARCHAR2(10)

SQL> insert into t2 values(':&nbnc');
Enter value for nbnc: rr
old 1: insert into t2 values(':&nbnc')
new 1: insert into t2 values(':rr')

1 row created.

SQL> SET DEFINE OFF
SQL> insert into t2 values(':&nbnc');

1 row created.

SQL>
