title: creation of trigger
body: <p>I have this trigger</p>
  
  <p></p>
  
  <pre><code>procedure CASE_A  
  as  
  UPDATE table1 SET field1 = (SELECT bus FROM view1 WHERE table1.document = view1.document)  
  end;
  </code></pre>
  
  <p></p>
  
  <p>the below trigger is supposed to execute the above procedure CASE_A (Case_A is supposed to put a value into field1)  </p>
  
  <p></p>
  
  <pre><code>CREATE OR REPLACE TRIGGER "CASE_A" AFTER INSERT ON "TABLE1" FOR EACH ROW  
  BEGIN  
  CASE_A;
  END;
  </code></pre>
  
  <p></p>
  
  <p>but, it's not doing that.  </p>
