SAS Query - Where data not present in one dataset

rakeshvvv — Wed, 08 Jun 2016 18:14:23 GMT

Dear All,

Can some one help me with below query. I have 1st dataset with three variables.

Id, date, term

I have second dataset with below three variables.

Term1,date1,id

For both the dataset ID is the primary key variable. I would like to write a query to output when TERM is not equal to TERM1. Term and Term1 will not be same sorting order for one to one match.

The output should look like this.

12004002 TRAMADOL UN/AUG/2014

12004002 MICONAZOL 18/JAN/2016

Thanks

Rakesh

Which variables are in the output? Term, Term1, Date or date1 (assuming that ID is one of the output variables).

I'm confused. If ID is the PK then there should be no sort order for term..?

What about dates? Do those have to match or be within a window of each other?

This may give what your are looking for if I understand the problem:

proc sql;
   create table want as
   select table1.id, table1.term,table1.date, table2.term1
   from table1 left join table2 
      on table1.id=table2.id
   where table1.term ne table2.term1;
quit;
