Hi, I would like to detect duplicate rows in my dataset below
data HAVE;
infile datalines dlm="|";
input COL1 :$5. COL2 :$5. COL3 :$5.;
datalines;
CAT|DOG|ANT
ANT|CAT|DOG
HORSE|CAT|HORSE
;
run;
*It's in Row 1 and 2.
/*Output Duplicates*/
data WANT;
infile datalines dlm="|";
input COL1 :$5. COL2 :$5. COL3 :$5.;
datalines;
CAT|DOG|ANT
ANT|CAT|DOG
;
run;
I'm not sure how to do it, I was thinking of transposing, sorting, then concatenation, but it seems not efficient. Perhaps there is a better way to do it. Thank you!
You can sort inline so to speak.
If you can have different cases (ie Ant vs ANT) they will not show up as duplicates.
Something like this, untested code:
data temp;
set have;
call sortc(col1, col2, col3);
run;
proc sort data=temp out=want nouniquekey;
by col1 col2 col3;
run;
