在 SQL 使用官方 IANA 时区数据库需要帮助
Need help using the official IANA timezone database in SQL
我正在使用 T-SQL 查询从 Azure SQL 数据库检索数据以实现客户数据可视化。
我需要一种方法来使用 IANA timezone 例如。 Europe/Copenhagen 转换为 UTC time 例如。 10-08-2020 12:32:00 到 local time 例如。 10-08-2020 14:32:00 在 SQL.
（注意UTC时间加了两个小时，因为当时UTC到哥本哈根的时差是夏令时两个小时。）
official IANA website has a downloadable timezone database，但我不明白如何实现它，特别是在 SQL 上下文中。
我花了很多时间试图破解这个挑战，我欢迎任何有用的输入。 Microsoft 生态系统中似乎不支持 IANA 时区标准。
微软SQL服务器
Microsoft SQL Server 支持时区，但可能不支持 IANA 标准。时区信息存储在 sys.time_zone_info.
select tzi.*
from sys.time_zone_info tzi
where tzi.name like '%copenhagen%'
or tzi.name like '%denmark%'
or tzi.name like '%europe%'
-- result (dst = daylight saving time)
name current_utc_offset is_currently_dst
-------------------------------- ------------------ ----------------
W. Europe Standard Time +02:00 1
Central Europe Standard Time +02:00 1
Central European Standard Time +02:00 1
E. Europe Standard Time +03:00 1
这些偏移量可以与 datetime 值组合，如图所示 。
您可以（手动）创建一个映射 table，将您数据集中的 IANA 时区映射到 sys.time_zone_info 中可用的时区。另一种方法是使用大型 CASE 语句查询 select 可用的最准确时区。
IANA 下载
在 SQL 中从可直接在 IANA 网站上下载的文件中导入数据将是一个巨大的挑战。我快速浏览了 tzdata2020a.tar.gz 下载中包含的 'README' 文件（使用您最喜欢的 zip 应用程序解压缩文件）。它包含一些 UNIX 风格的命令，用于在 OS（下面摘录）上安装时区。
make TOPDIR=$HOME/tzdir install
$HOME/tzdir/usr/bin/zdump -v America/Los_Angeles
实际的时区信息类似于下面的数据（摘自文件 'europe' 丹麦）。恐怕这需要大量的脚本来解析和导入 Microsoft SQL 服务器中所需的数据。
# Denmark, Faroe Islands, and Greenland
# From Jesper Nørgaard Welen (2005-04-26):
# http://www.hum.aau.dk/~poe/tid/tine/DanskTid.htm says that the law
# [introducing standard time] was in effect from 1894-01-01....
# The page http://www.retsinfo.dk/_GETDOCI_/ACCN/A18930008330-REGL
# confirms this, and states that the law was put forth 1893-03-29.
#
# The EU [actually, EEC and Euratom] treaty with effect from 1973:
# http://www.retsinfo.dk/_GETDOCI_/ACCN/A19722110030-REGL
#
# This provoked a new law from 1974 to make possible summer time changes
# in subsequent decrees with the law
# http://www.retsinfo.dk/_GETDOCI_/ACCN/A19740022330-REGL
#
# It seems however that no decree was set forward until 1980. I have
# not found any decree, but in another related law, the effecting DST
# changes are stated explicitly to be from 1980-04-06 at 02:00 to
# 1980-09-28 at 02:00. If this is true, this differs slightly from
# the EU rule in that DST runs to 02:00, not 03:00. We don't know
# when Denmark began using the EU rule correctly, but we have only
# confirmation of the 1980-time, so I presume it was correct in 1981:
# The law is about the management of the extra hour, concerning
# working hours reported and effect on obligatory-rest rules (which
# was suspended on that night):
# http://www.retsinfo.dk/_GETDOCI_/ACCN/C19801120554-REGL
# From Jesper Nørgaard Welen (2005-06-11):
# The Herning Folkeblad (1980-09-26) reported that the night between
# Saturday and Sunday the clock is set back from three to two.
# From Paul Eggert (2005-06-11):
# Hence the "02:00" of the 1980 law refers to standard time, not
# wall-clock time, and so the EU rules were in effect in 1980.

有点晚了，但对我来说，我通过 windows 和时区数据库之间的映射解决了问题。
以下 SQL 结果是一个映射。有一个列名 SQL_Names 应用与 [sys] 的连接。[Time_Zone_Info] table获取 SQL 下面的时区详细信息是示例。
注意： 由于此处的字符限制，JSON 并未涵盖所有时区，但您可以从以下链接导入完整列表。

此外，请参考以下链接：
我正在使用 T-SQL 查询从 Azure SQL 数据库检索数据以实现客户数据可视化。
我需要一种方法来使用 IANA timezone 例如。 Europe/Copenhagen 转换为 UTC time 例如。 10-08-2020 12:32:00 到 local time 例如。 10-08-2020 14:32:00 在 SQL.
（注意UTC时间加了两个小时，因为当时UTC到哥本哈根的时差是夏令时两个小时。）
official IANA website has a downloadable timezone database，但我不明白如何实现它，特别是在 SQL 上下文中。
我花了很多时间试图破解这个挑战，我欢迎任何有用的输入。 Microsoft 生态系统中似乎不支持 IANA 时区标准。
微软SQL服务器
Microsoft SQL Server 支持时区，但可能不支持 IANA 标准。时区信息存储在 sys.time_zone_info.
select tzi.*
from sys.time_zone_info tzi
where tzi.name like '%copenhagen%'
or tzi.name like '%denmark%'
or tzi.name like '%europe%'
-- result (dst = daylight saving time)
name current_utc_offset is_currently_dst
-------------------------------- ------------------ ----------------
W. Europe Standard Time +02:00 1
Central Europe Standard Time +02:00 1
Central European Standard Time +02:00 1
E. Europe Standard Time +03:00 1
这些偏移量可以与 datetime 值组合，如图所示
您可以（手动）创建一个映射 table，将您数据集中的 IANA 时区映射到 sys.time_zone_info 中可用的时区。另一种方法是使用大型 CASE 语句查询 select 可用的最准确时区。
IANA 下载
在 SQL 中从可直接在 IANA 网站上下载的文件中导入数据将是一个巨大的挑战。我快速浏览了 tzdata2020a.tar.gz 下载中包含的 'README' 文件（使用您最喜欢的 zip 应用程序解压缩文件）。它包含一些 UNIX 风格的命令，用于在 OS（下面摘录）上安装时区。
make TOPDIR=$HOME/tzdir install
$HOME/tzdir/usr/bin/zdump -v America/Los_Angeles
实际的时区信息类似于下面的数据（摘自文件 'europe' 丹麦）。恐怕这需要大量的脚本来解析和导入 Microsoft SQL 服务器中所需的数据。
# Denmark, Faroe Islands, and Greenland
# From Jesper Nørgaard Welen (2005-04-26):
# http://www.hum.aau.dk/~poe/tid/tine/DanskTid.htm says that the law
# [introducing standard time] was in effect from 1894-01-01....
# The page http://www.retsinfo.dk/_GETDOCI_/ACCN/A18930008330-REGL
# confirms this, and states that the law was put forth 1893-03-29.
#
# The EU [actually, EEC and Euratom] treaty with effect from 1973:
# http://www.retsinfo.dk/_GETDOCI_/ACCN/A19722110030-REGL
#
# This provoked a new law from 1974 to make possible summer time changes
# in subsequent decrees with the law
# http://www.retsinfo.dk/_GETDOCI_/ACCN/A19740022330-REGL
#
# It seems however that no decree was set forward until 1980. I have
# not found any decree, but in another related law, the effecting DST
# changes are stated explicitly to be from 1980-04-06 at 02:00 to
# 1980-09-28 at 02:00. If this is true, this differs slightly from
# the EU rule in that DST runs to 02:00, not 03:00. We don't know
# when Denmark began using the EU rule correctly, but we have only
# confirmation of the 1980-time, so I presume it was correct in 1981:
# The law is about the management of the extra hour, concerning
# working hours reported and effect on obligatory-rest rules (which
# was suspended on that night):
# http://www.retsinfo.dk/_GETDOCI_/ACCN/C19801120554-REGL
# From Jesper Nørgaard Welen (2005-06-11):
# The Herning Folkeblad (1980-09-26) reported that the night between
# Saturday and Sunday the clock is set back from three to two.
# From Paul Eggert (2005-06-11):
# Hence the "02:00" of the 1980 law refers to standard time, not
# wall-clock time, and so the EU rules were in effect in 1980.

有点晚了，但对我来说，我通过 windows 和时区数据库之间的映射解决了问题。
以下 SQL 结果是一个映射。有一个列名 SQL_Names 应用与 [sys] 的连接。[Time_Zone_Info] table获取 SQL 下面的时区详细信息是示例。
注意： 由于此处的字符限制，JSON 并未涵盖所有时区，但您可以从以下链接导入完整列表。
