title: Redshift SQL - Reverse Listagg function
body: <p>Suppose I have a table like below:</p>
  
  <pre><code>Name   Order
   AA     1,2
   BB     2,3
  </code></pre>
  
  <p>I want my result to be like:</p>
  
  <pre><code>Name   Order
   AA      1
   AA      2
   BB      2
   BB      3
  </code></pre>
  
  <p>How can I achieve this in Redshift?</p>
  
  <p>Thanks!</p>
