title: How to classify specific data in groups with an sql query
body: <p>I'm trying to make a query in sql to place specific data in groups.
  So I want to classify data in the next groups:</p>
  
  <pre><code>[1-90m²] group1
  [91-140m²] group2
  [141-190m²] group3
  [191-300m²] group4
  [300+m²] group5
  </code></pre>
  
  <p>But I only have the exact data.. <code>Example 87m² --&gt;[1-90m²] 160m² --&gt; [141-190m²]</code>.</p>
  
  <p>Does anyone know how to do this?
  Thanks!</p>
