Hi All,
I am trying to retrieve the missing variable of Table2 from Table1 (within by group). Can someone help with the code please.
I have the following two datasets:
Table1:
Student_ID Course
101 English
101 Biology
102 Chemistry
103 English
103 Physics
103 Accounting
104 Biology
104 Chemistry
Table2:
Student_ID Course
101 English
102 Chemistry
103 English
103 Accounting
104 Chemistry
Expected Output:
Student_ID Course
101 Biology
103 Physics
104 Biology
proc sql;
select a.*
from table1 A
left join table2 B on b.student_id = a.student_id and
b.course = a.course
where missing (b.student_id);
proc sql;
create table want as
select * from table1
except
select * from table2
;
quit;
If there are other variables needed you need to do some merging bak from the result to get them and have to replace the * with Student_Id, Course
