正在将数据从XML文档解析到数据库中

Question

我目前在标准web服务中有这个方法：

[WebMethod]
        public void addGame(int GamePlayID, int @ParticipantID, int @GameVersionID, string Start, string End,string success)
        {
            SqlConnection oConn = new SqlConnection();
            oConn.ConnectionString = @"Data Source=SNICKERSSQLEXPRESS;Initial Catalog=VerveDatabase;Integrated Security=True";
            oConn.Open();
            SqlCommand cmd = new SqlCommand();
            cmd.Connection = oConn;
            cmd.CommandType = CommandType.StoredProcedure;
            cmd.CommandText = "addGamePlay";
            cmd.Parameters.Add(new SqlParameter("@GamePlayID", SqlDbType.Int));
            cmd.Parameters["@GamePlayID"].Value = GamePlayID;
            cmd.Parameters.Add(new SqlParameter("@ParticipantID", SqlDbType.Int));
            cmd.Parameters["@ParticipantID"].Value = @ParticipantID;
            cmd.Parameters.Add(new SqlParameter("@GameVersionID", SqlDbType.Int));
            cmd.Parameters["@GameVersionID"].Value = @GameVersionID;
            cmd.Parameters.Add(new SqlParameter("@Start", SqlDbType.Time));
            cmd.Parameters["@Start"].Value = Start;
            cmd.Parameters.Add(new SqlParameter("@End", SqlDbType.Time));
            cmd.Parameters["@End"].Value = End;
            cmd.Parameters.Add(new SqlParameter("@success", SqlDbType.VarChar, 10));
            cmd.Parameters["@success"].Value = success;
            cmd.ExecuteNonQuery();
        }

这允许我将手动输入的值传递到数据库。但是，我希望能够从XML文档中加载数据。如何从这个XML文档中获取数据来填充这个方法中的变量。这是XML文档：

<?xml version="1.0" encoding="UTF-8"?>
<anyType xmlns="http://tempuri.org/" xmlns:d1p1="http://www.w3.org/2001/XMLSchema-instance" d1p1:type="q1:string" xmlns:q1="http://www.w3.org/2001/XMLSchema">
<NewDataSet>
<Game> 
<GamePlayID>1</GamePlayID>
            <ParticipantID>1</ParticipantID> 
<GameVersionID>1</GameVersionID> 
<Start-Time>PT0S</Start-Time> 
<End-Time>PT5H</End-Time> 
<Success>true </Success> 
</Game>
</NewDataSet>
</anyType>

Answer 1

您是否想过创建一个具有一个XML类型参数的存储过程并发送整个<NewDataSet>？您可以使用XQuery直接从XML类型插入到表中，类似于我的一个应用程序中的INSERT：

INSERT INTO CategoryItems (CategoryID, ItemID, SortOrderID) 
    SELECT @ID, 
        ParamValues.Item.value('./ID[1]', 'int'), 
        ParamValues.Item.value('./SortID[1]', 'int')
    FROM @Items.nodes('/Items/Item') AS ParamValues(Item) 

（@Items属于XML类型）

Answer 2

我不太明白为什么我被否决了，因为这是一个真正的问题，但我想我应该概述一下我是如何克服这个问题的。由于我的特殊XML文档只包含一个节点，我使用xmlDocument上的"selectSingleNode"函数来选择我想要的数据，并将它们分配给准备通过SQL proc插入数据库的变量。

[WebMethod]
        public void addGame()
        {
            XmlDocument xd = new XmlDocument();
            xd.Load(@"C:UsersbradleyaDocumentsVisual Studio 2010ProjectsWeb ServicesWeb ServicesaddGame.xml");
            XmlNode documentNode = xd.SelectSingleNode("/NewDataSet/Game");
            int GamePlayID = Convert.ToInt32(documentNode.SelectSingleNode("GamePlayID").InnerText);
            int ParticipantID = Convert.ToInt32(documentNode.SelectSingleNode("ParticipantID").InnerText);
            int GameVersionID = Convert.ToInt32(documentNode.SelectSingleNode("ParticipantID").InnerText);
            string Start = Convert.ToString(documentNode.SelectSingleNode("Start-Time").InnerText);
            string End = Convert.ToString(documentNode.SelectSingleNode("End-Time").InnerText);
            string success = Convert.ToString(documentNode.SelectSingleNode("Success").InnerText);
            SqlConnection oConn = new SqlConnection();
            oConn.ConnectionString = @"Data Source=SNICKERSSQLEXPRESS;Initial Catalog=VerveDatabase;Integrated Security=True";
            oConn.Open();
            SqlCommand cmd = new SqlCommand();
            cmd.Connection = oConn;
            cmd.CommandType = CommandType.StoredProcedure;
            cmd.CommandText = "addGamePlay";
            cmd.Parameters.Add(new SqlParameter("@GamePlayID", SqlDbType.Int));
            cmd.Parameters["@GamePlayID"].Value = GamePlayID;
            cmd.Parameters.Add(new SqlParameter("@ParticipantID", SqlDbType.Int));
            cmd.Parameters["@ParticipantID"].Value = @ParticipantID;
            cmd.Parameters.Add(new SqlParameter("@GameVersionID", SqlDbType.Int));
            cmd.Parameters["@GameVersionID"].Value = @GameVersionID;
            cmd.Parameters.Add(new SqlParameter("@Start", SqlDbType.Time));
            cmd.Parameters["@Start"].Value = Start;
            cmd.Parameters.Add(new SqlParameter("@End", SqlDbType.Time));
            cmd.Parameters["@End"].Value = End;
            cmd.Parameters.Add(new SqlParameter("@success", SqlDbType.VarChar, 10));
            cmd.Parameters["@success"].Value = success;
            cmd.ExecuteNonQuery();
        }
