body: <p>I just got to know about the global temporary tables(I use oracle as db) and understood them but not able to know the exact use of these.</p>
  
  <p>As the name suggests they are used to keep temporary data/session and on closing session the data vanishes for that session.</p>
  
  <p>What can be the examples, business use cases where we need to use them.</p>
