Question

我正在尝试将临时变量转换为UTC时间并使用以下内容打印它，

declare @dt datetime, @dtEnd datetime
set @dt = '2017-04-25' AT TIME ZONE 'UTC' 
set @dtEnd = '2017-04-30' AT TIME ZONE 'UTC' 

select dateadd(day, number, @dt)
from 
    (select distinct number from master.dbo.spt_values
     where name is null
    ) n
where dateadd(day, number, @dt) < @dtEnd

我从接受的答案here获得了此代码。我收到了一个错误，

参数数据类型varchar对于AT TIME ZONE的参数1无效功能

我正在使用SQL Server docs将CDT转换为UTC。链接的答案很适合在没有AT TIME ZONE 'UTC'的情况下打印。

如何在UTC时间内将临时变量转换为打印？

Answer 1

您需要使用强制转换作为日期时间

declare @dt datetime, @dtEnd datetime
set @dt = CAST('2017-04-25' AS DATETIME) AT TIME ZONE 'Central Standard Time' AT TIME ZONE 'UTC' 
set @dtEnd = CAST('2017-04-30' AS DATETIME) AT TIME ZONE 'Central Standard Time' AT TIME ZONE 'UTC' 

select dateadd(day, number, @dt)
from 
    (select distinct number from master.dbo.spt_values
     where name is null
    ) n
where dateadd(day, number, @dt) < @dtEnd

T-SQL中UTC时间的临时变量
