sql - How to remove rows related by name in Oracle

Question

I have the following records in a database table

ID   NAME         REF
-----------------------
1    ar.chik       33
4    ar.chik.rt    33
5    dy.i.op       35
9    dy.i

Which statement can remove the following records:

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

Answer 1

如果要删除表中与原始行相似的行name，则应该能够使用类似于以下内容的内容：

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

如果我明白你想要什么，你可以使用这个：

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

或者

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

或者，如果您想删除带有多个点的记录：

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

Answer 3

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