SQL> DEFINE dummy_char = 'X'
SQL> SELECT * FROM dual
  2   WHERE dummy = '&&dummy_char';
old   2:  where dummy = '&&dummy_char'
new   2:  where dummy = 'X'
D
-
X

Açıklaması şöyle

Notice that line 2, which contained the reference to the &&dummy_char substitution variable, was displayed before and after the reference to the variable was replaced by its value. If you don’t like this display, you can turn it off with SET VERIFY OFF.
