Problem Note 69668: Incorrect output might occur when you use the FEDSQL procedure and LIBNAME statements to join tables from different database management systems (DBMS)
 |  |  |  |  |
The FEDSQL procedure might return incorrect output when the following is true:
- You use two LIBNAME statements that reference a database management system (DBMS).
- You perform a join query.
- The join query contains the same column name for the different tables in the WHERE clause.
Here is an example of a query that might trigger this issue. In your code, the LIBNAME statements point to your database:
libname a ...;
libname b ...;
PROC FEDSQL;
SELECT DISTINCT reltab1."person_id", intab1."last_updated_at_dttm", idrun_prev."tab_person_wat_max_dttm", reltab1."last_updated_at_dttm", idrun_prev."tab_person_watchlist_t_max_dttm" FROM
"a"."person_watchlist" AS intab1,
"a"."person_watchlist_to_person" AS reltab1,
"b"."inteld_run" AS idrun_prev
WHERE
intab1."person_watchlist_id" = reltab1."person_watchlist_id"
AND (intab1."last_updated_at_dttm" > idrun_prev."tab_person_wat_max_dttm" OR
reltab1."last_updated_at_dttm" > idrun_prev."tab_person_watchlist_t_max_dttm" )
;
QUIT;
libname b ...;
PROC FEDSQL;
SELECT DISTINCT reltab1."person_id", intab1."last_updated_at_dttm", idrun_prev."tab_person_wat_max_dttm", reltab1."last_updated_at_dttm", idrun_prev."tab_person_watchlist_t_max_dttm" FROM
"a"."person_watchlist" AS intab1,
"a"."person_watchlist_to_person" AS reltab1,
"b"."inteld_run" AS idrun_prev
WHERE
intab1."person_watchlist_id" = reltab1."person_watchlist_id"
AND (intab1."last_updated_at_dttm" > idrun_prev."tab_person_wat_max_dttm" OR
reltab1."last_updated_at_dttm" > idrun_prev."tab_person_watchlist_t_max_dttm" )
