    Aggregating based on max timestamp

    Mark Perreault

      Hello All,


      The data I am working with can be updated over time and its important that the aggregations being calculated are based on the most recent update.  So for example I have the following table below.


      1102018-01-03 00:00:00
      1152018-01-02 00:00:00
      1202018-01-01 00:00:00
      252017-01-02 00:00:00
      282017-01-03 00:00:00
      2502017-01-01 00:00:00


      I want to sum customers across ID's based on their max update time so from this table I want my sum of customers to equal 18.

      10 from ID=1 where max Update is 2018-01-03 00:00:00 and 8 from ID=2 where max UpdateTime is 2017-01-03 00:00:00 .

      How would I calculate this?
