我有上面的xml文件。

在我的SQL Server 2008数据库有表Book__Master中的所有列都相同上述xml文件的元素，即有像列bookid，author，title等。

现在我想编写一个存储过程，它接受这个 xml 文件作为输入参数，并将元素的值按原样存储在它们各自的列中。

任何人都可以帮助我如何编写这种类型的存储过程？

Answer 1

您可以为此使用 X-Query：

SQL小提琴

MS SQL Server 2008 架构设置：

CREATE PROCEDURE dbo.ParseXML
   @XML XML
AS
BEGIN

  SELECT 
    Book.value('@id','NVARCHAR(100)') AS id,
    Book.value('author[1]','NVARCHAR(100)') AS author,
    Book.value('title[1]','NVARCHAR(100)') AS title,
    Book.value('price[1]','DECIMAL(10,4)') AS price,
    Book.value('publish_date[1]','DATE') AS publish_date

    FROM @XML.nodes('catalog/book')Catalog(Book)

RETURN;
END;

查询 1：

DECLARE @FileXML XML = '<?xml version="1.0"?>
<catalog>
   <book id="bk101">
      <author>Gambardella, Matthew</author>
      <title>XML Developer''s Guide</title>
      <genre>Computer</genre>
      <price>44.95</price>
      <publish_date>2000-10-01</publish_date>
      <description>An in-depth look at creating applications 
      with XML.</description>
   </book>
   <book id="bk102">
      <author>Ralls, Kim</author>
      <title>Midnight Rain</title>
      <genre>Fantasy</genre>
      <price>5.95</price>
      <publish_date>2000-12-16</publish_date>
      <description>A former architect battles corporate zombies, 
      an evil sorceress, and her own childhood to become queen 
      of the world.</description>
   </book>
</catalog>';

EXEC dbo.ParseXML @FileXML;

结果：

|    ID |               AUTHOR |                 TITLE | PRICE | PUBLISH_DATE |
|-------|----------------------|-----------------------|-------|--------------|
| bk101 | Gambardella, Matthew | XML Developer's Guide | 44.95 |   2000-10-01 |
| bk102 |           Ralls, Kim |         Midnight Rain |  5.95 |   2000-12-16 |

这将向您展示如何获取值。从那里您可以轻松地将它们插入到您的表中。
