title: How exactly setQueryMode of VO works?
body: <p>I am new to Oracle ADF and i am stuck in understanding concept of how queryMode works.<br>
  can some one please explain me following<br>
  --> what data will be in VO cache,EO cache when i do just vo.executeQuery()<br>
  --> what happens when i use setQueryMode() and does vo.executeQuery() with different modes like QUERY_MODE_SCAN_VIEW_ROWS,QUERY_MODE_SCAN_ENTITY_ROWS,QUERY_MODE_SCAN_DATABASE_TABLES|QUERY_MODE_SCAN_ENTITY_ROWS on the below table.<br>
  --> When we apply ViewCriteria with the above modes how it behaves.  </p>
  
  <p>lets take following table called InfoTable </p>
  
  <p>Id|StartDate|EndDate|Country|Status<br>
  56|01-APR-16|31-DEC-16|US|A<br>
  57|01-APR-16|31-DEC-16|IND|A<br>
  58|14-APR-16|31-DEC-16|UK|N  </p>
  
  <p>Note:Here PrimarKey(id,StartDate,EndDate)</p>
  
  <p>Can we visualize what data in EO,VO cache like data base tables?<br>
  Thanks in advance.</p>
