  <p>In SQL Server 2008 R2 I have a table (database size is 450 GB) with over a billion rows, which I'd like to purge by deleting all records older than 180 days counting from the current date. Any help here would be appreciated! </p>
  
  <p>I'm using the following query :</p>
  
  <pre><code>DELETE FROM table name 
  WHERE column name &lt; '2015-01-01' 
  </code></pre>
  
  <p>But it is taking too much time. Is there any maintenance plan or any query so that I can delete the data fast? </p>
