title: PL SQL trigger using raise_application_error thows error.
body: <p>I have a few things of code I need help debugging but I feel that if I can get one of them running i'll be able to get the rest(oh how i hope).</p>
  
  <pre><code>create or replace 
  trigger minimumwage
  before insert or update on Employee
  for each row
  begin
  if :new.Wage &lt; 7.25 
  then raise_application_error('-20000,Pay is below Texas minimum wage!');
  end if;
  end;
  /
  </code></pre>
  
  <p>I'm trying to do this on a table ran on my school's server through sqlplus if that helps. </p>
