Oracle FETCH FIRST 1 ROW с оператор UNION ALL

Просто поставете всяка част в скоби. Работи в 12.2, така или иначе:

( Select * From tabl1 where Date = '04-MAR-2020' FETCH FIRST 1 ROW )
UNION ALL
( Select * From tabl1 where Date = '05-MAR-2020' FETCH FIRST 1 ROW )

Действителната ми тестова заявка за всеки, който се интересува, беше следната:

(select   object_name 
 from     user_objects 
 where    object_type = 'TABLE' 
 order by object_name 
 fetch first 1 row only)
UNION ALL
(select   object_name 
 from     user_objects 
 where    object_type = 'VIEW' 
 order by object_name 
 fetch first 1 row only);
