title: SQL: Conditional Insert/Update
body: <p>Hi I am working with a table like the one below in SAP HANA:</p>
  
  <pre><code>Outcome  Value  Rating
  Yes       0      null
  Yes       20     null
  No       -16     null
  </code></pre>
  
  <p>I need to populate the Rating column conditionally so that if: </p>
  
  <pre><code>Value &gt; 15; Rating = 'High"
  -15 &lt;= Value &lt;= 15; Rating = 'Medium" 
  Value &lt; -15; Rating = 'Low"
  </code></pre>
  
  <p>Is there anyway I can do this using an INSERT or UPDATE statement?</p>
