title: SQL use column name alias without SELECTING
body: <p>I know I can specify a column alias like so:</p>
  
  <pre><code>SELECT stuff as mask
  </code></pre>
  
  <p>Is there a way I can specify a column alias <em>without</em> returning that column data in the result set?  Essentially, I want to be able to make my query clean by doing:</p>
  
  <pre><code>SELECT doManipulationStuff(cleanCompactAlias)
  </code></pre>
  
  <p>Where</p>
  
  <pre><code>reallyLong.misleading.andAnnoying.columnName as cleanCompactAlias
  </code></pre>
