  <p>In the above table email_ids are repeated, I want to display all emails in the above table with out repetition.</p>
  
  <p>Here there is only 4 emails, I want to retrieve only 4 rows from table is this possible using GQL query in goolge app engine.</p>
  
  <p>And one more thing i want to use paging to display emails (10 emails for a page), </p>
  
  <p>i.e., if there is 15 emails in table, need to display 10 emails in 1ST page and 5 emails in 2nd page.   </p>
  
  <p>Paging is very important! </p>
