title: Display record even if it doesn't exist
body: <p>So I have this table</p>
  
  <pre><code>Col1    Col2    Col3
  A       34       X
  B       43       L
  A       36       L
  </code></pre>
  
  <p>Now if I query</p>
  
  <pre><code>select * from Table1 where col1 in ('A','B','C')
  </code></pre>
  
  <p>I am expecting something like</p>
  
  <pre><code>Col1    Col2    Col3
  A       34       X
  B       43       L
  A       36       L
  C       -        -
  </code></pre>
  
  <p>Is it possible ? </p>
  
  <p>P.S: the <code>-</code> in row C are just to show that the column is empty. </p>
