Solution 1

maybe :
select * from database1.table1 where to_char(column1, 'DD-MM-YYYY') not in (select to_char(column1, 'DD-MM-YYYY') from database2.table2 where order_date>sysdate-1)

and check that db2 can be accesed from db1, that is GRANT SELECT TO DB2.Table2 ON DB1

Solution 2

(select * from T1 minus select * from T2)
union all
(select * from T2 minus select * from T1);
