如何从表中的单个列检索匹配值？

Question

我有一张下表

Id     Avatar
1      Smarty.resident
2      ticklethis.resident
3      Renae resident
4      ticklethis
5      Smarty resident
6      Hirpantemp
7      loveyoubaby
8      Hirpantemp.resident
9      Renae
10     Sweetme
11     ticklethis resident

我无法编写SQL命令来获取类似名称，如下面的

Id     Avatar
1      Smarty.resident
5      Smarty resident
2      ticklethis.resident
4      ticklethis
11     ticklethis resident
3      Renae resident
9      Renae
6      Hirpantemp
8      Hirpantemp.resident

对于替换中的假设，这有点可疑，但这可能适用于给定的数据集：

select ID, Avatar
from MyTable
where replace(replace(Avatar, '.resident', ''), ' resident', '') in (
    select replace(replace(Avatar, '.resident', ''), ' resident', '') as Avatar
    from MyTable
    group by replace(replace(Avatar, '.resident', ''), ' resident', '')
    having count(*) > 1
)
