Oracle SQL，范围在1-1000之间

我有一个包含数字的表，范围在1-1000之间，它们是唯一的，但我需要使用Oracle SQL确定表中1-1000范围内缺少哪些数字

1,3,4,5,6,8,9,10

结果2,7

有人能帮我写一个脚本或一个脚本的URL吗

您可以使用：

select level from dual
connect by level<=1000
minus
select mycolumn from mytable

编辑：

要找出序列中没有硬编码1000的数字，请执行以下操作：

select level from dual
connect by level < (select max(mycolumn) from mytable)
minus
select mycolumn from mytable

尝试：

11、12等呢？他们不也失踪了吗？不，因为计数还没有达到那么高，但我可以用maxSheetNo作为高点。

select a.check_number
from (select level check_number from dual connect by level <= 1000) a
where not exists 
(select null from myTable t where a.check_number = t.lookup_number)

with numbers as (
   select level as i
   from dual 
   connect by level <= (select max(some_number) from your_table)
) 
select nr.i as missing
from numbers nr
  left join your_table yt on yt.some_number = nr.i
where  yt.some_number is null;
