  Yes the num column is unique, but the best thing to use would be ID as the same records would have the same ID.

  Jeff Moden (5/30/2013)

  So, any feedback on my previous comment of...

  Like I said, if the "Num" column is the wrong thing to consider to be unique, then we'll have to change a couple of indexes and a couple of column names.

  WHICH ID? Certainly not the HistoryID, right?

  --Jeff Moden

  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.

  ok....will throw in an idea for you to consider.

  first off...the script you posted above will not work...you need to test this before you post.

  I leave you to sort that..

  second you fail to provide data for all columns

  third...your sample of dates (days) is only two dates....???

  anyways, based on what I think you need here is some code to play with

  #1621338

  suggest you revisit the solution that Jeff Moden gave you.....just swap out the table name and I think you will need to replace "Num" with "PID"...that should give you what you want.

  suggest you revisit the solution that Jeff Moden gave you.....just swap out the table name and I think you will need to replace "Num" with "PID"...that should give you what you want.

  I just haven't had the time to come up with good example data. You should take the time to either install the AdventureWorks database or read the solution code I posted to warp it to your needs or read the first link in my signature line below for how to post some usable data for us to demonstrate a solution with.

  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.

  by the way..you really do need to understand the code and how it works...you after all are going to have to support it. If you care to read all the comments Jeff has kindly included...this will give you a good start...post back with questions as necessary.
