Selecting data based timestamp and a special code

  • An example of data I have is as follows:

    Entry_ID TimeStamp Activity_Code

    670242 2010-02-15 12:15:00 P

    680243 2010-02-15 15:30:00 P

    692451 2010-02-15 12:45:00 P

    I am trying to write a Case statement that retrieves each row individually. And, I need a unique name for each such as P_1, P_2, etc.

    An example of my code is

    (Case When ACTIVITY_CODE = 'P' Then CONVERT(nvarchar(5), STARTTIME, 108)Else '' End) as P1_start,

    This would work if there was only one listing for the P activity code. However, there are multiple listings.

    I think I need to add "AND" and something else to identify each of these separately.

    Any suggestions are appreciated.

  • Are you trying to turn the rows into columns? I'm not entirely clear on what end result you want here.

  • Entry_ID TimeStamp Activity_Code

    670242 2010-02-15 12:15:00 P

    680243 2010-02-15 15:30:00 P

    No, I am not trying to turn rows into columns. The End result would be to assign a unique column name based on the Activity Code - P and the order of the timestamps. Therefore, the records above would be P1_start, P2_start and P3_start. This will be coded within a Case/When statement. The entry_Ids are not specific. I cannot code it by the entry_id.

  • I am currently exploring the rank function. Hopefully, this will work.
