select * from [Nop_ProductVariantAttributeValue]
where [Name] in (select [Name] from [Nop_ProductVariantAttributeValue] group by [Name] having(count(*))=1)
--用主键去过滤
select * from [Nop_ProductVariantAttributeValue] a
where not exists
(select 1 from [Nop_ProductVariantAttributeValue]
where a.name=name and 主键<a.主键)--如果多主键 就主键1+主键2<a.主键1+a.主键2
------解决方案-------------------- select a.*
from [Nop_ProductVariantAttributeValue] a
inner join
(select name,min(id) id from [Nop_ProductVariantAttributeValue] group by name) b
on a.id=b.id
