title: Checking rows that are not numbers in a varchar column for MySQL Query
body: <p>In a perfect world for this type of setup, we would have an integer column that expects only numbers;</p>
  
  <p>But what if you have a <code>varchar</code> column and you want to add a <code>WHERE</code> clause that said something like this:</p>
  
  <p><code>WHERE &lt;value&gt; is NOT a number</code></p>
  
  <p>In essence, you are selecting all rows that contain any characters that are NOT ONLY numbers.</p>
  
  <p>This is for MySQL.</p>
