如何在SQL Server中选择没有主键的重复记录

Question

如果我运行此查询:

SELECT 
        a,
        b,
        c,
        ...
FROM    [DMS].[dbo].[CreditDebitAdjustment]

我得到了24197条记录.

如果我运行此查询:

SELECT  DISTINCT
        a,
        b,
        c,
        ...
FROM    [DMS].[dbo].[CreditDebitAdjustment]

我得到了24176条记录.

如何仅选择相同的行？

Answer 1

SELECT 
        a,
        b,
        c
FROM    [DMS].[dbo].[CreditDebitAdjustment]
group by a,b,c
having count(*) > 1
