使用ASP.Net insert命令应用于ORACLE数据库表

你好！我试图在ORACLE数据库表中的单个字段中仅插入一个实体，但堆栈跟踪中出现以下错误：

**Stack Trace**: 

[OracleException（0x80131938）：ORA-12154:TNS:无法解析指定的连接标识符 ] System.Data.OracleClient.OracleException.Check（OCIRorHandle errorHandle，Int32 rc）+338968 System.Data.OracleClient.OracleInternalConnection.OpenOnLocalTransaction（字符串用户名、字符串密码、字符串服务器名、布尔集成安全性、布尔unicode、布尔省略OracleConnectionName）+879 System.Data.OracleClient.OracleInternalConnection..ctor（OracleConnectionString connectionOptions）+129 System.Data.OracleClient.OracleConnectionFactory.CreateConnection（DbConnectionOptions选项、对象池组ProviderInfo、DbConnectionPool池、DBConnectionOwningObject）+40 System.Data.ProviderBase.DbConnectionFactory.CreatePooledConnection（DbConnection所有者连接、DbConnectionPool池、DbConnectionOptions选项）+31 System.Data.ProviderBase.DbConnectionPool.CreateObject（DbConnection-owningObject）+548 System.Data.ProviderBase.DbConnectionPool.UserCreateRequest（DbConnection owningObject）+69 System.Data.ProviderBase.DbConnectionPool.GetConnection（DbConnection owningObject）+470 System.Data.ProviderBase.DbConnectionFactory.GetConnection（DbConnection-owningConnection）+108 System.Data.ProviderBase.DbConnectionClosed.OpenConnection（DbConnection outerConnection，DbConnectionFactory connectionFactory）+118 System.Data.OracleClient.OracleConnection.Open（）+43 System.Web.UI.WebControls.SqlDataSourceView.ExecuteDbCommand（DbCommand命令，DataSourceOperation操作）+378 System.Web.UI.WebControls.SqlDataSourceView.ExecuteInsert（IDictionary值）+399 System.Web.UI.WebControls.SqlDataSource.Insert（）+19 ASP.jtrap\u import\u aspx.InsertWeight（对象源，事件参数e）在e:\Documents\Visual Studio 2013\Projects\jtrap\u net v1\jtrap\u net\jtrap\u import.aspx:12中 System.Web.UI.WebControls.Button.OnClick（EventArgs e）+9628722 System.Web.UI.WebControl.Button.RaisePostBackEvent（String eventArgument）+103 System.Web.UI.WebControl.Button.System.Web.UI.IPostBackEventHandler.RaisePostBackEvent（String eventArgument）+10 System.Web.UI.Page.RaisePostBackEvent（IPostBackEventHandler sourceControl，String eventArgument）+13 System.Web.UI.Page.RaisePostBackEvent（NameValueCollection postData）+35 System.Web.UI.Page.ProcessRequestMain（布尔includeStagesBeforeAsyncPoint，布尔includeStagesAfterAsyncPoint）+1724

这是我的数据源：

<asp:Sqldatasource
ID="OracleServer1" Runat="server" 
ConnectionString="Data Source=OracleServer1;Persist Security Info=True;"
ProviderName="System.Data.OracleClient"
InsertCommand="INSERT INTO tbl_object(WEIGHT) VALUES(@Weigh)">
      <insertparameters>
        <asp:formparameter name="Weigh" formfield="TextBox1" />            
      </insertparameters>
</asp:Sqldatasource>

这是我的连接字符串，位于my Web.config中：

<connectionStrings>

 <add name="OracleConnectionString" 
  connectionString="Data Source=OracleServer1;Persist 
  Security Info=True;" 
  providerName="System.Data.OracleClient" 
/>

谢谢你的帮助

我在“代码隐藏”中做了一个更好的选择，因为我更熟悉这种方法并使其工作：

代码隐藏：

    Dim strConnection As String = ConfigurationManager.ConnectionStrings("OracleConnectionString").ConnectionString
    Dim oracleConnection As New Oracle.DataAccess.Client.OracleConnection(strConnection)

    If oracleConnection.State = ConnectionState.Closed Then
        MsgBox("Opening oracle connection")
        oracleConnection.Open()
        MsgBox("Oracle connection successfully opened.")
    End If


    Dim strQuery As String = "INSERT INTO ......(so on)"
    Dim oracleCommand As New OracleCommand(strQuery, oracleConnection)

    MsgBox("Inserting values to the table")

    oracleCommand.ExecuteNonQuery()

    MsgBox("Successfully inserted values into the table")

这是我在web.config文件中的连接字符串代码

<connectionStrings>
 <add name="OracleConnectionString" 
  connectionString="Data Source=localhost;USER ID=username;PASSWORD=password" 
  providerName="Oracle.DataAccess.Client" 
/>  </connectionStrings>

那么，您的连接字符串与您机器上的TNS条目不匹配。尝试ti-TNSPING OracleServer1时会发生什么？
