title: Reset PK auto increment column
body: <p>I've been importing thousands of records multiple times in an effort to get the import running perfectly.</p>
  
  <p>As a result, now when I do the live import before release, the ID columns for the auto increment column are on around 300,000.</p>
  
  <p>Is there any easy way to 'reset' this once I have deleted all the data from these tables?  I only want to for SEO reasons, the URL:</p>
  
  <pre><code>Forum/1/Post
  Forum/35/Post
  Forum/5600/Post
  </code></pre>
  
  <p>Looks a lot nicer and more concise (therefore more clickable in results) than</p>
  
  <pre><code>Forum/300124/Post
  Forum/370321/Post
  Forum/450111/Post
  </code></pre>
  
  <p>I'd rather not delete the column and reinsert the column as it would ruin all relationships and mean I'd have to refresh all my data context diagrams etc.</p>
