从选择查询输出中删除重复项

任何人都可以请建议在下面的查询中出现什么错误？其实我想从选择查询输出中删除所有重复项，并只提取唯一的行。提前致谢。从选择查询输出中删除重复项

把它放在Excel中，然后单击”删除重复“按钮？在您将大量未格式化的文字墙倾倒在我们身上后，没有人会帮助您。 – DavidG

SELECT DISTINCT？ – Juan

我尝试了不同的。但它不起作用。 – Che

首先，您必须定义要调用“唯一行”的内容。

一旦你拥有了一套确定的行是唯一的列，这是一组你在row_number()

在下面的代码的partition by部分使用的列，取消对列集定义你的“独特行“：

select * 

    from (
    select ROW_NUMBER() over (
    partition by 
     Dep 
    --, tariffkode 
    --, LinkTariffType 
    --, poliata 
    --, poliatavia 
    --, podiata 
    --, podiatavia 
    --, PreCarriage 
    --, PortTerminalId 
    --, Product 
    --, RoutingOrder 
    --, PrepaidCollect 
    --, isnull(description, '') 
    --, ScaleCalcCode 
    --, isnull(scalefrom, 0) 
    --, isnull(scaleto, 0) 
    --, CurrencyCode 
    --, Base 
    order by LinkTariffType desc 
    ) Record 
    , *

感谢您的回复。仍然在声明“）as b where b.Record = 1）”的行处得到相同的错误“。该错误表示“语法不正确”），期望AS，ID或QUOTED_ID。“同时我找到了另一种解决这个问题的方法。我已经使用CTE来存储内部选择查询中的所有行，然后我已将该分区应用于CTE的内容。 – Che

@Che更新为尝试修复您的其他错误 – SqlZim

非常感谢！它的工作..... :) – Che
