title: ORACLE SQL APEX using sequence numbers gives an missing expression error
body: <p>I created sequence for manager first.</p>
  <pre><code>CREATE SEQUENCE manager_seq
  START WITH 200
  MAXVALUE 299
  CYCLE 
  CACHE 10;
  </code></pre>
  <p>Then I inserted some values using .NEXTVAL</p>
  <pre><code>INSERT INTO manager
  VALUES (manager_seq.NEXTVAL,'')
  </code></pre>
  <p>When I try to query with where statement it says    ORA-00936: missing expression</p>
  <pre><code>select * from manager where number = 201;
  </code></pre>
  <p>Why it isn't working with sequnce numbers how can I use them?</p>
