title: Delete row in mysql
body: <p>I am building JSP application in which I want to do following operations on specific table</p>
  
  <ul>
  <li>Display Data</li>
  <li>Delete Data</li>
  </ul>
  
  <p>I've done displaying data, however:</p>
  
  <p>How can I delete a row in database if the table does not have any primary key ? (Delete operation does not depends on any value of that row)</p>
  
  <p>Suppose here is may table -->> mytemp
  Here is the data</p>
  
  <pre><code>Name | RollNo
  ABC  |  98
  XYZ  |  76
  ABC  |  98
  XYZ  |  76
  </code></pre>
  
  <p>There is no key in this table and i want to delete 3 rd record. How can i do this ?</p>
