如何在没有主键的表中检测/删除数据库中的重复条目？

[如果我们使用’DISTINCT’我们怎么知道哪个记录是正确的并且重复一个？ ]

解决方法

delete f
from
(
    select ROW_NUMBER() 
        over (partition by 
            YourFirstPossibleDuplicateField,YourSecondPossibleDuplicateField
            order by WhateverFieldYouWantSortedBy) as DelId
    from YourTable
) as f
where DelId > 1
