如何在 SQL 中将时间转换为 IST？
How to get time converted to IST in SQL?
我在一个名为 DPSDateTime 的 SQL 数据表中有数据。下面显示的是具有值的数据列：
crea_date Disp_Day Disp_Time State TimeZone
11/13/14 5:56 PM Thursday, December 18, 2014 19:00:09 IL (GMT-06:00) Central Time (US & Canada)

12/23/14 4:37 PM Friday, December 26, 2014 15:28:04 MD (GMT-05:00) Eastern Time (US & Canada)
在上面的 table crae_date 列中有 DateTime 值和 State 和 TimeZone 列显示 crea_date 列中值的相应 Sate 和 TimeZones。
我想按名称 ISTTime 添加另一列。我想在此列中显示转换为 IST（印度标准时间）的 crea_date 列的值。
我查看了“How to convert between time zones in SQL Server 2008?”中提供的解决方案。这提供了将单个值转换为另一个 TimeZone 的方法。我需要将具有不同时区的整个列转换为 IST。
提前致谢。
尝试此查询以将时间转换为 IST：
SELECT SWITCHOFFSET(SYSDATETIMEOFFSET(), '+05:30')
