  I have a table like this...

  mobilenumber activationdate status

  12345 01/01/2009 Pending

  12345 01/04/2009 Pending

  12345 04/06/2009 Active

  12345 04/10/2009 Active

  56789 12/01/2008 Pending

  56789 03/02/2009 Pending

  I need the output like this:

  mobilenumber activationdate status

  12345 04/10/2009 Active

  56789 03/02/2009 Pending

  Need to retrieve the latest acvitation date and the status of the mobilenumber in the table. What is the best way to do it?

  Thanks,

  Ramu

  WITH CTE AS (

  SELECT mobilenumber,activationdate,status,

  ROW_NUMBER() OVER(PARTITION BY mobilenumber ORDER BY activationdate DESC) as rn)

  SELECT mobilenumber,activationdate,statu

  FROM CTE

  WHERE rn=1
