title: sql server management studio syntax
body: <p>Can some one explain the significant of the brackets that MSManagement Studio always encapsulates columns in queries with. 
  Ex..</p>
  
  <pre><code>SELECT TOP 1000 [id]
    ,[app_fn]
    ,[app_mn]
    ,[app_ln]
    ,[app_suffix]
  </code></pre>
  
  <p>What are they there for, and how can I use this to my advantage?</p>
