Answer 1

看起来你需要这样的东西：

WITH
  DEFAULT 'http://www.ecb.int/vocabulary/2002-08-01/eurofxref',
  'http://www.gesmes.org/xml/2002-08-01' AS gesmes)
INSERT YourRateTable (Currency, Rate)
SELECT
  x.cube.value('@currency','char(3)'),
  x.cube.value('@rate','decimal(18,9)')
FROM @xml.nodes('/gesmes:Envelope/Cube/Cube/Cube') x(cube);

要将您的数据导入 SQL Server，不要尝试使用诸如 sp_OA 之类的技巧来加载数据。

改为使用类似 Powershell Invoke-WebRequest 的东西，并使用 Invoke-SqlCmd 或 dba-tools 的 Invoke-Query 传递它

Install-Module dbatools

$xml = (Invoke-WebRequest -Uri "https://www.ecb.europa.eu/stats/eurofxref/eurofxref-daily.xml").Content;

$query = @"THEABOVEQUERY";

Invoke-DbaQuery -SqlInstance "yourserver" -Query $query -SqlParameter @{ Name = "@xml"; Value = $xml; SqlDbType = "Xml" };
