title: Can Hibernate check conflicts (Java)
body: <p>First of all I want you to know I am very new to Hibernate.</p>
  
  <p>I have a MySQL table Account (composite key: account_name &amp; server)
  I need to check if there exists the account_name on a given server before inserting it.</p>
  
  <p>Not sure if Hibernate can do the check. If yes, how?</p>
  
  <p>I appreciate your time and reply. Thanks!</p>
