title: AND operator in DB2 constraints
body: <p>I am trying to add following constraint to my DB2 table but it gives error.</p>
  
  <pre><code>ALTER TABLE Table_name ADD CONSTRAINT VALID_BINDING 
  CHECK((LOWER(REQ_BINDING) IN ('http-post','http-redirect'))
  AND ((LOWER(RESP_BINDING) IN ('http-post','http-redirect')));
  </code></pre>
  
  <p>Is this a valid query. Can I use AND operator in it?</p>
