如何在sqlserver中获取不同的记录

Question

FUNDFAMILY_ID    FUND_NAME                REPORTSECTION_ID           
--------------------------------------------------------------
172295295    VANGUARD GROWTH FUND (Retail)  126345
172295295    VANGUARD GROWTH FUND (Retail)  126354
--------------------------------------------------------------

但我需要得到如下结果:

FUNDFAMILY_ID     FUND_NAME                   REPORTSECTION_ID
--------------------------------------------------------------
172295295   VANGUARD GROWTH FUND (Retail)   126345

在存储过程内部,我有一个像下面的查询,它给出了重复的行

    INSERT INTO #TABLE_REPORTSECTIONDATA (FUND_NAME, FUNDFAMILY_ID, REPORTSECTION_ID)

                SELECT DISTINCT @FUNDNAME_TEMP , @FUNDID_TEMP, EntryPointViewsId
                FROM EntryPointViews EPV
                ORDER BY EntryPointViewsId

DISTINCT关键字没有给我正确的结果.请建议

Answer 1

DISTINCT为您提供正确的结果,记录与您指定的所有列不同.你想要什么呢？根据ID和描述只是唯一的？哪个AnotherID想从每个小组拿走？

如果你只是想要一个任意你可以使用MIN或MAX与GROUP BY:

SELECT ID, Description, MIN(AnotherID)
FROM EntryPointViews EPV
GROUP BY ID, Description
