Sql oracle表中的最后一项

我想在oracle中创建一个查询，该查询将显示我创建的表中的最后一个条目，我尝试通过max和through date进行查询，但在max之后，查询不准确，到期日显示所有日期，我将非常感谢您的帮助。）

日期之后

select seal_number 
  from SEC_OBJECT_SEALING 
 where SEALING_OBJECT = :P26_OBJECT_UNPLUG 
   and (to_date(data ,'dd.mm.yyyy hh24:mi:ss') = 
       (select max(to_date(data ,'dd.mm.yyyy hh24:mi:ss')) from SEC_OBJECT_SEALING)

通过max

select seal_number 
  from SEC_OBJECT_SEALING 
 where SEALING_OBJECT = :P26_OBJECT_UNPLUG 
   and id = (select max(id) from SEC_OBJECT_SEALING)

---

在Oracle 12+中，使用

fetch

：

select seal_number
from SEC_OBJECT_SEALING
where SEALING_OBJECT = :P26_OBJECT_UNPLUG 
order by data desc
fetch first 1 row only;

在早期版本中，使用子查询：

select sos.*
from (select seal_number
      from SEC_OBJECT_SEALING
      where SEALING_OBJECT = :P26_OBJECT_UNPLUG 
      order by data desc
     ) sos
where rownum = 1;
