title: Unable to insert mail@id in oracle table
body: <p>I am unable to insert email id in the oracle 9i tables.
  I am using putty.</p>
  
  <p><code>INSERT INTO email(mail_list)values('sundar@abc.com');</code></p>
  
  <p>I m getting the below error:
  SQL> INSERT INTO email(mail_list)values('sundar@
  abc.com');
  <code>SP2-0042: unknown command "abc.com')" - rest of line ignored.</code></p>
  
  <p>Putty is not accepting <code>@</code> symbol. </p>
  
  <p>I have read the below in one of the portal:</p>
  
  <p><code>The problem is common with unix environment with the display terminal keyboard settings. The sqlplus session had trouble interpreting the "@" sign, because it was assigned in the terminal to the "kill" setting.</code></p>
  
  <p>how to correct the issue?</p>
  
  <p>Thanks</p>
