title: Exclude columns from Minus operations in oracle sql
body: <p>I'd like to know if you can exclude a column from a <code>MINUS</code> operation</p>
  
  <p>For example:</p>
  
  <pre><code>select column 1, column 2, column 3
  from table 1
  
  minus
  
  select column 1, column 2
  from table 2;
  </code></pre>
  
  <p>while column 3 is excluded from the operation.</p>
  
  <p>Is there anyway to do that?</p>
  
  <p>Thank you</p>
