title: SQLDeveloper - Join between DBs without CREATE DATABASE LINK privileges
body: <p>i am trying to figure out, how to JOIN tables from two different oracle databases in SQLDeveloper, which I currently can access only isolated/separately from each other.
  The Problem is: Our company has restricted the CREATE DATABASE LINK privileges, so there is no chance to get this done this way. (The database is a read-only DB).
  Is there another way to join the databases? It is only necessary for diagnostics and data-flow observation. </p>
  
  <p>Any help or hints appreciated.</p>
  
  <p>Kind Regards.</p>
