4 ar.chik.rt 33 
5 dy.i.op  35 
9 dy.i 

以下記錄哪種說法可以刪除以下記錄：

ID NAME   REF 
------------------------ 
4 ar.chik.rt 33 
5 d.yi.op  35 

Answer 1

如果你想刪除您的表類似於原來name行，那麼你應該能夠使用的東西類似如下：

delete 
from yourtable 
where id in (select id 
      from 
      (
       select id, 
       row_number() over(partition by ref 
            order by length(name)) rn 
       from yourtable 
      ) d 
      where rn > 1);

Answer 2

如果我通情達理你想要什麼，您可以使用此：

DELETE FROM Yourtable WHERE name='ar.chik.rt' OR name='d.yi.op' ; 

或

DELETE FROM Yourtable WHERE name IN ('ar.chik.rt','d.yi.op') ; 

，或者如果你想多點刪除記錄：

DELETE FROM Yourtable WHERE name LIKE '%.%.%' ; 

Answer 3

delete from Yourtable 
where id in(4,5);
