title: How to find tables with foreign keys that reference a specific table
body: <p>Suppose my database contains the following tables :</p>
  
  <ul>
  <li><strong><code>table_A</code></strong> with primary key <em><code>PKA</code></em></li>
  <li><strong><code>table_B</code></strong> with foreign key <em><code>FKA</code></em></li>
  </ul>
  
  <p>Suppose also that I have no clue of the content of the database, except that it contains a table named <strong><code>table_A</code></strong>.</p>
  
  <p>Here is my question : given <strong><code>table_A</code></strong>'s name, what (PL/)SQL request do I have to make to the database to know that there is a table B that has a foreign key to table A ?</p>
  
  <p>I'm using Oracle 11g</p>
