title: Unpivot columns to generate rows
body: <p>I have a query like this:</p>
  
  <pre><code>SELECT '35111212', '11245452', '42215512'...... and more values.
  </code></pre>
  
  <p>This results in:</p>
  
  <pre><code>(No column name)    (No column name)    (No column name)
  --------           --------            --------
  35111212           11245452            42215512
  </code></pre>
  
  <p>And I need to transform it to:</p>
  
  <pre><code>(No column name)
  --------
  35111212
  11245452
  42215512
  </code></pre>
  
  <p>Is that possible without using a "union"? I have a large amount of values in the select.</p>
