title: Find a Database table's unique constraint
body: <p>I'm trying to find the unique constraints of a table using Java (on an Oracle Database, but that should make no difference).</p>
  
  <p>I found a way to discover the Primary Keys of a table, thanks to DatabaseMetaData's getPrimaryKeys(....);
  However I was unable to find the unique constaints of the tables, and the Internet was not able to help me, therefore I'm ending here asking my question :)</p>
  
  <p>Is there a clean way to find the unique constraints (or, rather, the name of the columns that must be unique for a table.. Well you get it hehe) of a table ? 
  Best regards, </p>
