Trying to create the table below, i.e. adding another condition in the codes where if there is same Event_date then only Count_done as 1.
PROC SQL;
Create Table want1 as select
want.*, source.result_date,
case
when standard_days ge result_date and Event_date le result_date then '1'
else '0'
end
as Count_done
from want left join source on want.ID = source.ID;
Quit;
Current code produces this:
ID | Event_date | Count_done |
123456 | 17/07/2018 | 1 |
123456 | 17/07/2018 | 1 |
234567 | 12/07/2018 | 1 |
This is what I want:
ID | Event_date | Count_done |
123456 | 17/07/2018 | 1 |
123456 | 17/07/2018 | 0 |
234567 | 12/07/2018 | 1 |
Thanks in advance
Why would you want to do that in SQL?
data want;
set have;
by id event_date;
count_done = first.event_date;
run;
