获取表格中的每一行副本

我有代码抓取SQL表中的重复项，并通过跟踪编号对它们进行分组。我希望看到每一行重复，而不是只有他们组。用于获取组重复的代码如下：获取表格中的每一行副本

该表的唯一行标识符是什么？ – egrunin 2012-07-30 18:30:43

有一个GUID字段。所以每一行都是唯一的，但我需要找到具有相同跟踪编号和总费用的行。 – Jeff 2012-07-30 18:34:28

你可以使用CTE吗？ – wildplasser 2012-07-30 19:00:51

查找重复的FIELD1（和场2，评论）：

SELECT t1.* 

    FROM test t1 

    INNER JOIN test t2 
    ON t2.field1 = t1.field1 -- AND t2.field2 = t1.field2 

    WHERE t1.id <> t2.id

如果热膨胀系数可用（也可以用子选择来完成）：

WITH dups AS (
     SELECT TrackingNumber, TotalCharges 
     FROM Prasco_GencoShipments 
     GROUP BY TrackingNumber, TotalCharges 
     HAVING COUNT(*) > 1 
     ) 
SELECT ta.* 
FROM Prasco_GencoShipments ta 
JOIN dups du ON du.TrackingNumber = ta.TrackingNumber AND du.TotalCharges = ta.TotalCharges 
ORDER BY 
     TrackingNumber 
     , TotalCharges 
     ;
