title: Update table using multi record block in post forms commit
body: <p>what I wanted is to update my table using values from a multi record block and here is what I tried in post forms commit:</p>
  
  <pre><code>BEGIN
      FIRST_RECORD;
      LOOP 
          UPDATE table1         
          SET ord_no = :blk.new_val;
          EXIT WHEN :SYSTEM.LAST_RECORD='TRUE';
          NEXT_RECORD;
      END LOOP;
  END;
  </code></pre>
  
  <p>but when I save I got an error </p>
