Question

有一个创建Excel文件的过程，选择结果保存在其中。该文件附在信件上并通过邮件发送。但是问题在于该文件已创建并发送为空。手动操作一切正常，但不能同时使用。

是的， JGFMK 是正确的！如果执行此代码，则将执行openrowset：

;With Numbered as (
    select *,ROW_NUMBER() OVER (
             PARTITION BY CUST_ID
             ORDER BY LAST_ACTIVITY_DATE desc) rn
    from Account
)
select ACCOUNT_ID,AVAIL_BALANCE,OPEN_DATE,LAST_ACTIVITY_DATE 
from Numbered 
where rn=1

如何使其根据条件起作用？

将结果查询到xlsx并在SQL Server中发送邮件
