I have Dataset A and Dataset B both with the variables Imb_code and Rule_Number. I need to keep only records in Dataset A that do not exist in Dataset B. In Oracle SQL I would use a Minus operator, something like this...
select imb_code, rule_number
from TableA
Minus
select imb_code, rule_number
from TableA;
How would this best be done in SAS?
Try the ANSI SQL Set operator EXCEPT.
Another option would be to left join and filter out matches (test on IMB_CODE IS NULL).
Really struggling here with syntax. Any chance someone can throw our an example of these two suggestions?
As Linus suggests EXCEPT is the solution here e.g.
data tablea;
infile datalines dlm=",";
input imb_code rule_number;
datalines;
1,9
2,8
3,7
4,6
5,5
;
run;
data tableb;
infile datalines dlm=",";
input imb_code rule_number;
datalines;
1,9
4,6
;
run;
proc sql;
create table tablec as
select * from tablea
except
select * from tableb
;
quit;
