Question

我在数据库表中有以下记录

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

哪条语句可以删除以下记录：

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

Answer 1

如果您要删除表格中与原始name类似的行，那么您应该可以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

如果我理解了你想要的东西，你可以使用它：

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') ;

或者如果您想要删除多个点的记录：

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

Answer 3

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