Problem Note 62004: The SAS/ACCESS® engine ignores blank values when you use the WHERE clause with PROC SQL
 |  |  |  |  |
Blank values are ignored when you subset a database management system (DBMS) table with a WHERE clause using the SQL procedure. You encounter this issue when you run code that is similar to the following:
proc sql;
select * from x.zz where name = '';
quit;
select * from x.zz where name = '';
quit;
To circumvent the problem, use DATA step code that is similar to the following:
data zz;
set x.zz;
where name = '';
run;
set x.zz;
where name = '';
run;
