  Hi All,

  I have the table with following data:

  Claim_ID,ClaimStatusCode,Statusdate,cycle

  40356442,Closed,2/1/2008,1

  40356442,Open,2/6/2008,1

  40363300,Closed,6/4/2008,1

  40363300,Open,6/17/2008,1

  40363300,Closed,3/23/2009,2

  40365497,Closed,7/30/2010,1

  40365497,Open,8/3/2010,1

  40365497,Closed,6/27/2011,2

  40365497,Open,6/30/2011,2

  40374968,Closed,12/19/2007,1

  40374968,Open,12/24/2007,1

  40374968,Open,9/8/2008,1 --to be deleted

  40389312,Closed,1/4/2008,1

  40389312,Open,1/18/2008,1

  40389312,Open,10/21/2008,1 --to be deleted

  40390976,Closed,2/12/2009,1

  40390976,Open,2/17/2009,1

  40390976,Closed,4/6/2010,2

  40390976,Open,4/8/2010,2

  40390976,Closed,3/18/2011,3

  Cycle represent the number from closed status till open, if there is other next closed , then it will be next cycle.

  Result: For each claim_Id if the last two statusdates are Open, then it should delete the max Open statusdate, that is

  Claim_ID,ClaimStatusCode,Statusdate,cycle

  40356442,Closed,2/1/2008,1

  40356442,Open,2/6/2008,1

  40363300,Closed,6/4/2008,1

  40363300,Open,6/17/2008,1

  40363300,Closed,3/23/2009,2

  40365497,Closed,7/30/2010,1

  40365497,Open,8/3/2010,1

  40365497,Closed,6/27/2011,2

  40365497,Open,6/30/2011,2

  40374968,Closed,12/19/2007,1

  40374968,Open,12/24/2007,1

  40389312,Closed,1/4/2008,1

  40389312,Open,1/18/2008,1

  40390976,Closed,2/12/2009,1

  40390976,Open,2/17/2009,1

  40390976,Closed,4/6/2010,2

  40390976,Open,4/8/2010,2

  40390976,Closed,3/18/2011,3

  records tobe deleted from table are:

  40374968,Open,9/8/2008,1 --to be deleted

  40389312,Open,10/21/2008,1 --to be deleted

  i tried doing this by max date join with table and row_number as well, but no luck.

  Any help is aprreciated.

  Thanks,

  Punia

  I would start with

  ROW_NUMBER() OVER (PARTITION BY Claim_ID ORDER BY Statusdate ) +

  ROW_Number() OVER (PARTITION BY Claim_ID,ClaimStatusCode ORDER BY Statusdate desc)

  to get a group number per consecutive range.

  Depending on the requirements (only find the latest duplicate or all dupes after the the first one in the last group e.g. in order to delete the last two if there are three) I might add another row_number to get groups numbered internally.

  I believe that I'd like to know how a claim was closed before it was opened. From the original data...

  40389312 ,Closed ,1/4/2008 ,1

  40389312 ,Open ,1/18/2008 ,1

  40389312 ,Open ,10/21/2008 ,1 --to be deleted

  Is that because the "Closed" may have had an earlier "Open" outside of "the cycle"?

  RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
  First step towards the paradigm shift of writing Set Based code:
  ________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

  Change is inevitable... Change for the better is not.
