Hi guys,
I have a dataset like this below:
id type Score
100 A 12
100 A 11
101 B 10
101 A 9
101 C 12
102 B 13
102 B 5
102 B 7
103 A 4
103 C 6
........
...........
and i need to exctract the IDs which have different values of "type". In my case that would be id=101 and 103 but i got no clue how to approach it. Any hints please?
Thx
proc sql ;
select id
from have
group by id
having count(distinct type)>1
;
quit;
