title: create a table based on other tables
body: <p>I have 4 different tables:</p>
  
  <pre><code>student: sid, name, gender 
  
  grades: sid, grade
  
  address: postcode, sid, distance_to_school
  
  health_condition: sid, health_code
  </code></pre>
  
  <p>Now I want to make a new table that contains all of the columns that I mentioned above. I need to join them based on the <code>sid</code>. I tried to add columns separately but the code is really long. So is there another way to do this task?</p>
