從oracle的列的值集中減去一些常數值

Question

有一個像id- name-roll這樣的表我有一些恆定的給定值roll like-（1,2,6,8,5）的集合讓它被設置一個表有roll like（1,2,3,4 ，5,6,7）設為集合B我想知道AB表示那些不在表中但存在於給定常量集合A中的roll值

我嘗試從“表名”中選擇卷，而不是卷（1,2,6,8,5）; 但它返回正好相反-它返回BA，但我要AB請幫助我也嘗試過

從雙減中選擇（1,2,6,8,5）從表名中選擇滾動； 但是它會產生一些同步錯誤

Answer 1

這是你想要的嗎？

select a.*
from (select 1 as id from dual union all
      select 2 as id from dual union all
      select 6 as id from dual union all
      select 8 as id from dual union all
      select 5 as id from dual
     ) a
where not exists (select 1 from b where a.id = b.id);

Answer 2

(select 1 as id from dual
         union all
select 2 from dual
         union all
select 6 from dual
         union all
select 8 from dual
         union all
select 5 from dual
         )
minus
Select id from b
