title: Getting common fields of two tables in PL/SQL
body: <p>Suppose <code> Table A </code> and <code> Table B </code> have various fields. What is an easy way to get the common fields among <code> Table A </code> and <code> Table B </code>? I want to do an inner join on these tables but I don't know what the common fields are.</p>
  
  <p>Note that this is in PL/SQL. When I table <code> A. </code> or <code> B. </code> I get the list of fields names of each table in a drop down menu. But I would like to get the common fields.</p>
