1) I have a dataset A (having millions of records) in LASR library.
2) Importing B file with few hundred rows.
3) Need to compare A and B and delete common records from A (lasr library) without creating a temporary copy.
Solution:
Using imstat statement--(not working)
proc imstat data=LASRLIB.A;
merge LASRLIB.A (in=a)
B (in=b);
if a and b;
run;
deleterows / purge;
run;
(Note: Merge not working with proc imstat.)
Is there any other way to do it?
Got the solution!
Storing all unique values in macro variable and passing in where clause of proc imstat.
proc imstat = lasrlib.A;
where column = ¯o;
run;
deleterows / purge;
run;
