title: How to switch Keyspace in Cassandra using CQL?
body: <p>I used <code>USE billKeyspace;</code> to enter a keyspace and start using it. Now I want to exit this keyspace and enter another keyspace. How to do that?</p>
  
  <p>If I use <code>exit;</code> or <code>quit;</code> it exits out of cql session itself and then I have to connect again. </p>
