title: Add pseudo column in select statement
body: <p>I have following data in table <code>student</code></p>
  <div class="s-table-container">
  <table class="s-table">
  <thead>
  <tr>
  <th>s_id</th>
  <th>s_subject</th>
  <th>s_marks</th>
  </tr>
  </thead>
  <tbody>
  <tr>
  <td>1</td>
  <td>English</td>
  <td>30</td>
  </tr>
  <tr>
  <td>2</td>
  <td>Hindi</td>
  <td>50</td>
  </tr>
  </tbody>
  </table>
  </div>
  <p>How I want to represent</p>
  <div class="s-table-container">
  <table class="s-table">
  <thead>
  <tr>
  <th>s_id</th>
  <th>s_name</th>
  <th>s_subject</th>
  <th>s_marks</th>
  </tr>
  </thead>
  <tbody>
  <tr>
  <td>1</td>
  <td>Student</td>
  <td>English</td>
  <td>30</td>
  </tr>
  <tr>
  <td>2</td>
  <td>Student</td>
  <td>Hindi</td>
  <td>50</td>
  </tr>
  </tbody>
  </table>
  </div>
  <p>This s_name should come as <code>Student</code> for all the <code>s_id</code>. Basically I want to mask the student_name</p>
  <p><code>SELECT s_id, s_subject, s_marks FROM student</code> will give me what in table, now how to add extra column in select statement with a mask name... One extra column with same value throughout...</p>
