How to get last date
Hi, I am new here!
I have a dataset that has data on multiple rows for the same patient with different encounter dates. I want to only see the unique patient once (so patient ID is the identifier) and show me only the most recent encounter date. Example data:
John Doe, Patient ID 1, encounter date 1/3/2022
John Doe, Patient ID 1, encounter date 3/5/2022
Jane Doe, Patient ID 3, encounter date 10/1/2022
John Smith, Patient ID 2, encounter date 3/1/2022
John Smith, Patient ID 2, encounter date 1/5/2022
John Smith, Patient ID 2, encounter date 6/4/2022
I have tried grouping methods in ETL and that hasn't worked. Can someone please help me?

Use a group by tile to group on the name / ID and then take the maximum of your date field.

@ageibe You can do this with the Group By tile in Magic ETL.
In section #1 (select what columns identify the grouping) put your name and patient Id columns in that section.
In section #2 enter the name you want to give the most recent date column
In section #3 choose the encounter date column and then choose maximum for the aggregation type.
This will give you the most recent encounter date for each patient.
