title: How to replace multiple strings in SQL?
body: <p>I looked up a discussion in SO with the link below :
  <a href="https://stackoverflow.com/questions/22496761/replace-multiple-characters-in-sql">Replace multiple characters in SQL</a></p>
  
  <p>What I am not able to understand is why the query is not working for :</p>
  
  <pre><code>select table_value, 
     replace(replace(replace(table_value, 'M', 'MEETING'), 'E', 'EMAIL'), 'P', 'PHONE') required_value 
  from foobar
  </code></pre>
  
  <p>I am a beginner learner in SQL and want to understand what's wrong with the above query ?
  I'd appreciate if someone could help me picturise the backend working here.</p>
  
  <p>The accepted answer in that blog is not the ultimate solution. I wanna know what to do when I come across a situation where there are multiple strings in a column which needs to be replaced? </p>
  
  <p>Is there an easy and efficient alternative or not?</p>
  
  <p>Thanks in advance</p>
