title: How to get available space in tablespace for a user (Oracle)
body: <p>I'm working on a web application where I need to warn the user that they're running out of space in the given db user's tablespace.
  The application doesn't know the credentials of the db's system user, so I can't query views like dba_users, dba_free_space..etc.</p>
  
  <p>My question is, is there a way in Oracle for a user to find out how much space there is left for them in their tablespace?</p>
  
  <p>Thanks!</p>
