title: Is there a way to sort by a string filed that contains number, by the value of the number?
body: <p>I have records with column record_id which is constructed from letters and numbers</p>
  
  <p>eg </p>
  
  <pre><code>a1
  a2
  a11
  a12
  b1
  </code></pre>
  
  <p>If i sort this I would get</p>
  
  <pre><code>a1
  a11
  a12
  a2
  b1
  </code></pre>
  
  <p>i was wondering if there is a way to sort this by letter then by the value of the number as the following</p>
  
  <pre><code>a1
  a2
  a11
  a12
  b1
  </code></pre>
