In a sas compare, output only differences and new records












0















In a compare with id, how can I output only the difference and the new records
but not the old records no more present?



Example, suppose I have two tables:



mybase:



    key other
1 Ann
3 Ann
4 Charlie
5 Emily


and mycompare:



    key other
2 Bill
3 Charlie
4 Charlie


running:



    proc compare data=mybase
compare=mycompare
outnoequal
outdif
out=myoutput
listvar
outcomp
outbase
method = absolute
criterion = 0.0001
;
id key;
run;


I get a table "myoutput" like this:



    type    obs key other
base 1 1 Ann
compare 1 2 Bill
base 2 3 Ann
compare 2 3 Charlie
dif 2 3 XXXXXXX
base 4 5 Emily


I would like to have this:



    type    obs key other
compare 1 2 Bill
base 2 3 Ann
compare 2 3 Charlie
dif 2 3 XXXXXXX

  • I don't see an option for that in PROC COMPARE. Might be forced to add a pre-processing step where you merge MyBase and MyCompare by ID, and delete any records from MyBase where the ID is not in MyCompare. Then you can run PROC COMPARE with the updated version of MyBase.
