sql - 在 SQL Server 的存储过程中解析 XML 并输出

问题描述

这是 XML 模式：

<details schemaVersion="1">
  <dataWarning>
    <Locations>
      <Failed_to_Create LocationID="1234">Location<Location_Description>TEST</Location_Description><FacilityID>TEST</FacilityID><Active>Y</Active></Failed_to_Create>
    </Locations>
  </dataWarning>
</details>

如何解析 XML 以便能够在存储过程中显示它？

谢谢！

解决方案

安德里亚，你需要更加自律。您有责任提供 DDL 和样本数据群。

SQL

-- DDL and sample data population, start
DECLARE @tbl TABLE  (ID INT IDENTITY(1,1) PRIMARY KEY, Details XML);
INSERT INTO @tbl (Details)
VALUES
(N'<details schemaVersion="1">
  <dataWarning>
    <Locations>
      <Failed_to_Create LocationID="1234">Location<Location_Description>TEST</Location_Description><FacilityID>TEST</FacilityID><Active>Y</Active></Failed_to_Create>
    </Locations>
  </dataWarning>
</details>')
, (N'<details schemaVersion="1">
  <dataWarning>
    <Locations>
      <Failed_to_Create LocationID="5678">Location<Location_Description>Real Description</Location_Description><FacilityID>770</FacilityID><Active>N</Active></Failed_to_Create>
    </Locations>
  </dataWarning>
</details>');
-- DDL and sample data population, end

SELECT c.value('@LocationID', 'VARCHAR(10)') AS [locationID]
    , c.value('(Location_Description/text())[1]', 'VARCHAR(100)') AS [Location_Description]
    , c.value('(FacilityID/text())[1]', 'VARCHAR(100)') AS [FacilityID]
    , c.value('(Active/text())[1]', 'VARCHAR(100)') AS [Active]
FROM @tbl AS tbl
      CROSS APPLY tbl.Details.nodes('/details/dataWarning/Locations/Failed_to_Create') AS t(c);

输出

+------------+----------------------+------------+--------+
| locationID | Location_Description | FacilityID | Active |
+------------+----------------------+------------+--------+
|       1234 | TEST                 | TEST       | Y      |
|       5678 | Real Description     | 770        | N      |
+------------+----------------------+------------+--------+
