title: Mysql comparing the values of two columns in the same row(s) in a single table
body: <p>I have been searching for a query to compare values in single rows in the same table.</p>
  
  <p>Example table:  </p>
  
  <pre class="lang-sql prettyprint-override"><code>SKU        Description   SKU   Category  
  173406926  Widgets       1734  
  137406927  Widgets-Blue  1734
  </code></pre>
  
  <p>I need to find the rows where the SKU number does not start with the SKU Category number (as in row two above)</p>
