title: PL/SQL function insert into table with pause
body: <p>I need to create a function, which inserts values into a table until I break it.
  So I realized the function with a loop. 
  But I need to pause the loop after every insert for just one second, because otherwise the database is running out of memory after a short while. </p>
  
  <p>I've tried it with system pause but that's stops the whole instance.</p>
  
  <p>It would be very nice if any one has a idea to resolve this.</p>
  
  <p>Greetings </p>
