WHERE clause with exclusion

mlogan — Thu, 17 Nov 2016 03:33:12 GMT

I have the folowinf table, can someone tell me how do I get all score greater than or equals 17 (excluding Clurse_ID=Eng). I mean observations where Course_ID=Eng should not be in considered in this clause. Thanks.

DATA Apple.have;
input Student_ID $ Course_ID $ Score;
cards; 
F103 Bio 18
F103 Math 15
F103 Eng 16
F103 Che 15
F103 Math 20
F103 Phy 17
M101 Eng 20
M101 Bio 20
M101 Eng 10
M101 Math 18
RUN;

Output table:

F103 Bio 18
F103 Eng 16
F103 Math 20
F103 Phy 17
M101 Eng 20
M101 Bio 20
M101 Math 18

Add your conditions as:

DATA Apple.have;
input Student_ID $ Course_ID $ Score;
if score ge 17 or course_id eq 'ENG';
cards; 
.... your data ...
;
run;

DATA WANT;
SET Apple.HAVE (WHERE =(Score >= 17 or Course_ID = 'Eng' ));
RUN;

4 F103 Phy 17
5 M101 Eng 20

Sorry, what are you trying to say here?

Obs 2 & 7 would be excluded otherwise, but they're included because Course_ID="ENG"

Yeah ..But mlogan desired output has not included the 7th observation [7 M101 Eng 10] . I just added that note .

Ah, you're correct, good catch!

But my guess is its an oversight on @mlogan part. I guess he can respond either way!
