I have a table as below:
id grade course
15 A class1
15 class1
17 B class1
17 A class2
20 class2
20 C class2
21 class1
I need to pull only one row with grade if the id and course same. I mean as below:
id grade course
15 A class1
17 B class1
17 A class2
20 C class2
21 class1
Thank you
Sort your table by id and course and use nodupkey option.
then drop the uncessory observations with grade = " "
You could try it this way:
proc sort data=have;
by id course grade;
run;
data want;
set have;
by id course;
if last.course;
run;
