Problem Note 19473: Certain query generates unexpected PROC SQL in SAS® Enterprise Guide®
A query that generates code similar to the following in SAS Enterprise
Guide 4.1.0.471 or 4.1.0.485 to join two tables with a WHERE clause that
has an OR operator:
create table work.ab as select a.id,
a.number,
a.age,
b.height
from work.a as a
inner join work.b as b on (a.id = b.id) and
(a.number = b.number)
where a.age >= 50 or b.height >= 170;
might generate code similar to the following in SAS Enterprise Guide
4.1.0.495 and might return unexpected results:
create table work.ab as select a.id,
a.number,
a.age,
b.height
from work.a as a,
work.b as b
where a.id = b.id and
a.number = b.number and
a.age >= 50 or b.height >= 170;
To circumvent the problem, create multiple queries, two to subset the
data with a WHERE clause and a third query to join the two resulting
tables.
