title: Table or view doesn't exist when DBlink is wrong
body: <p>If I run the below query, I'm getting <strong>ORA-02019 connection description for remote database not found</strong> as the DBlink <strong>BLAH</strong> is not there.</p>
  
  <pre><code>SELECT * FROM DUAL@BLAH;
  </code></pre>
  
  <p>But if I put it in an anonymous block, its giving <strong>ORA-00942 table or view does not exist</strong> error.</p>
  
  <pre><code>BEGIN
    SELECT * FROM DUAL@BLAH;
  EXCEPTION
    WHEN OTHERS THEN
      NULL;
  END;
  </code></pre>
