title: T-SQL - Aliasing using "=" versus "as"
body: <p>Is there any particular reason (performance or otherwise) to use AS ahead of = when aliasing a column?</p>
  
  <p>My personal preference (for readability) is to use this:</p>
  
  <pre><code>select
  alias1     = somecolumn
  alias2     = anothercolumn
  from
  tables
  etc...
  </code></pre>
  
  <p>instead of this:</p>
  
  <pre><code>select
  somecolumn as alias1
  anothercolumn as alias2
  from
  tables
  etc...
  </code></pre>
  
  <p>Am I missing out on any reason why I shouldn't be doing this? What are other people's preferences when it comes to formatting their columns?</p>
