Hello, Have a table PersonID, Event, Date. I currently have in the script to label event based on the beginning of value in load script.
if(left(event,4)='9921','LABELX','') as VISITTYPE
However If PersonID does not have a 9921 label then I want to label the first event that starts with 9920 for each PersonID. If it shows up a 2nd etc.. time don't label for that PersonID.
The table is already in chronological order.
