title: SQL select performance top 1 VS select 1
body: <pre><code>select 1 from someTable where someColumn = #
  </code></pre>
  
  <p>or</p>
  
  <pre><code>select top 1 someColumn1 from someTable where someColumn2 = #
  </code></pre>
  
  <p>which one will be faster on a large scale table...
  got no indexes at all on that table so that wont work.</p>
  
  <p>thanks.</p>
