Question

我正在SQL中运行此查询：

select
--CLAIM_ID,
--sum (paid_amount),
(ROW_NUMBER() OVER (partition by claim_id order BY claim_id) as asdf)
from [FRAUD].[dbo].[MU_GAPA_ADS_CLAIM_ANALYSIS_ALLACCOUNTS]
where (ALTGRP like '48000%') and (svcDAT between '10/01/2016' and '10/01/2016') 
Group By claim_id

但是，我听到以下错误消息：

第156条消息，级别15，状态1，第4行关键字“ as”附近的语法不正确。

有人可以帮助我了解发生了什么以及如何解决吗？

谢谢。

问题不是row_number()。问题是列别名周围的括号：

ROW_NUMBER() OVER (partition by claim_id order BY claim_id) as asdf

您还应该修复日期常数：

select CLAIM_ID, sum(paid_amount),
       row_number() over (partition by claim_id order by claim_id) as asdf)
from [FRAUD].[dbo].[MU_GAPA_ADS_CLAIM_ANALYSIS_ALLACCOUNTS]
where ALTGRP like '48000%' and
     svcDAT between '2016-10-01' and '2016-10-01'
Group By claim_id;

总而言之，row_number()总是会为该查询返回“ 1”，因此您最好将其省略。
