I recieved ERROR: Expression using equals (=) has components that are of different data types. When all my variables in the statement are NUMERIC. I ran PROC CONTENTS to double check. Here is my Code:

proc sql;
create table birth_temp_hum as
select*
from birth_temp hum1
where birth_temp.dateofbirth=hum1.strdate and birth_temp.V001=hum1.DHSCLUST
order by birth_temp.CASEID;
quit;

Proc Contents results: From Hum1

Your SQL FROM clause is essentially the problem here, not the where clause. It should say:

from birth_temp,hum1

with a comma between birth_temp and hum1.
