如何将XML从C#传递到SQL Server 2008中的存储过程？

Question

我想将xml文件传递给sql server存储过程,如下所示:

CREATE PROCEDURE BookDetails_Insert (@xml xml)

我想比较一些字段数据与其他表数据,如果匹配,则必须将记录插入到表中.

要求:

1. 如何将XML传递给存储过程？我试过这个,但它不起作用:[工作]

   command.Parameters.Add(
       new SqlParameter("@xml", SqlDbType.Xml)
       {
           Value = new SqlXml(new XmlTextReader(xmlToSave.InnerXml,
                              XmlNodeType.Document, null))
       });
   

2. 如何访问存储过程中的XML数据？

 String sql = "BookDetails_Insert";
        XmlDocument xmlToSave = new XmlDocument();
        xmlToSave.Load("C:\\Documents and Settings\\Desktop\\XML_Report\\Books_1.xml");

        SqlConnection sqlCon = new SqlConnection("...");
        using (DbCommand command = sqlCon.CreateCommand())
        {
            **command.CommandType = CommandType.StoredProcedure;**
            command.CommandText = sql;
            command.Parameters.Add(
              new SqlParameter("@xml", SqlDbType.Xml)
              {
                  Value = new SqlXml(new XmlTextReader(xmlToSave.InnerXml
                             , XmlNodeType.Document, null))
              });

            sqlCon.Open();
            DbTransaction trans = sqlCon.BeginTransaction();
            command.Transaction = trans;

            try
            {
                command.ExecuteNonQuery();
                trans.Commit();
                sqlCon.Close();
            }
            catch (Exception)
            {
                trans.Rollback();
                sqlCon.Close();
                throw;
            }

Answer 1

对于你的问题,看我的回答的第2部分存储过程:通过XML作为参数,并将(键/值对)对于如何在存储过程中使用XML的例子.

编辑:下面的示例代码基于评论中给出的具体示例.

declare @MyXML xml

set @MyXML = '<booksdetail> 
                  <isbn_13>700001048</isbn_13> 
                  <isbn_10>01048B</isbn_10> 
                  <Image_URL>http://www.landt.com/Books/large/00/70100048.jpg</Image_URL> 
                  <title>QUICK AND FLUPKE</title> 
                  <Description> PRANKS AND JOKES QUICK AND FLUPKE - CATASTROPHE QUICK AND FLUPKE </Description> 
              </booksdetail>'

select Book.detail.value('(isbn_13/text())[1]','varchar(100)') as isbn_13, 
       Book.detail.value('(isbn_10/text())[1]','varchar(100)') as isbn_10, 
       Book.detail.value('(Image_URL/text())[1]','varchar(100)') as Image_URL, 
       Book.detail.value('(title/text())[1]','varchar(100)') as title, 
       Book.detail.value('(Description/text())[1]','varchar(100)') as Description
    from @MyXML.nodes('/booksdetail') as Book(detail)
