Problem Note 33094: Incorrect results might be generated when you use the LIBNAME statement to join multiple Oracle tables
 |  |  |  |  |
Incorrect results might be generated when you use the Oracle access engine in a LIBNAME statement to join multiple Oracle tables and when the query contains both inner and outer joins. The results are incorrect because one of the join criteria is left out when the query is passed to Oracle.
The following example code shows a query that demonstrates this behavior:
proc sql;
select t3.zip_id,t3z.zip_id
from test.SERVICE T5,
test.CARE T1
left join
test.product T11
on T1.GRP_ID = T11.GRP_ID,
test.MEMBER T3
left join test.ZIP_CODE T3Z
on T3.ZIP_ID=T3Z.ZIP_ID
where T5.SERV_ID=T1.SERV_ID
and T3.MBR_ID=T1.MBR_ID;
quit;
In this case, the condition joining T3 and T3Z is not included in what is sent to Oracle to be processed. If you use the SASTRACE= option, you can see the query that is submitted to Oracle by SAS:
select T3."ZIP_ID", T3Z."ZIP_ID"
from SERVICE T5, CARE T1, PRODUCT T11, MEMBER T3, ZIP_CODE T3Z
where T1."GRP_ID" = T11."GRP_ID" (+) and
((T5."SERV_ID" = T1."SERV_ID") and
(T3."MBR_ID" = T1."MBR_ID"))

Note: This problem does not occur in SAS® 9.2.
