存储过程不更新在asp.net触发的sql表格

Question

我有一个网站，其中一个表格将显示资产列表和他们的信息从SQL中的表中拉出。如果有必要，我有一个部分按钮，一个职员可以通过在文本或下拉字段中输入新内容来按下和修改现有信息。这是使用存储过程完成的;一切似乎运行良好，直到你检查工作，没有任何更新！

这里是编辑信息的代码;

protected void ADD_Click(object sender, EventArgs e) 
{ 
    using (SqlConnection connection = new SqlConnection(WebConfigurationManager.ConnectionStrings["DATASYSTEMS"].ConnectionString)) 
    { 
     SqlCommand cmd = new SqlCommand("UPDATING_ASSETS", connection); 
     cmd.CommandType = CommandType.StoredProcedure; 
     cmd.Parameters.AddWithValue("@ASSET_NUMBER", Txtasset_number.Text); 
     cmd.Parameters.AddWithValue("@MACHINE_NAME", Txtmachine_name.Text); 
     cmd.Parameters.AddWithValue("@PORT_NUMBER", Txtport_number.Text); 
     cmd.Parameters.AddWithValue("@BUILDING_NUMBER", DPBUILDING.SelectedValue); 
     cmd.Parameters.AddWithValue("@ROOM_NUMBER", Txtroom_number.Text); 
     cmd.Parameters.AddWithValue("@TELEPHONE_NUMBER", Txttelephone_number.Text); 
     cmd.Parameters.AddWithValue("@FLOOR", Txtfloor.Text); 
     cmd.Parameters.AddWithValue("@SERIAL", Txtserial.Text); 
     cmd.Parameters.AddWithValue("@TYPE", DPTYPE.SelectedValue); 
     cmd.Parameters.AddWithValue("@BRANCH", DPBRANCH.SelectedValue); 
     cmd.Parameters.AddWithValue("@SECTION", DPSECTION.SelectedValue); 
     cmd.Parameters.AddWithValue("@USERS", txtuser1.Text); 
     ClientScript.RegisterClientScriptBlock(this.GetType(), "key", "<script type='text/javascript'>alert('Record has been updated.');window.location='navigation.aspx';</script>"); 
    } 
} 
protected void dglocaltables_SelectedIndexChanged(object sender, EventArgs e) 
{ 

} 

}

这里是应该更新的存储过程。

CREATE PROCEDURE [dbo].[update_TBL_INFO_1] @ASSET_NUMBER as nvarchar(50), @PORT_NUMBER as nvarchar(50), @MACHINE_NAME as nvarchar(50), @TYPE as nvarchar(50) , @BRANCH as nvarchar(50), @SECTION as nvarchar(50), @BUILDING_NUMBER as nvarchar(50), @ROOM_NUMBER as nvarchar(50), @TELEPHONE_NUMBER as nvarchar (50), @FLOOR as nvarchar (50), @USERS as nvarchar (50), @ID as float (8), @SERIAL as nvarchar (50) as 

If (SELECT ASSET_NUMBER FROM dbo.TBL_INFO WHERE ASSET_NUMBER=@ASSET_NUMBER AND [ID]=@ID)=@ASSET_NUMBER 
BEGIN 
    If (SELECT MACHINE_NAME FROM dbo.TBL_INFO WHERE MACHINE_NAME=@MACHINE_NAME AND [ID]=@ID)=@MACHINE_NAME 
    BEGIN 
     If (SELECT PORT_NUMBER FROM dbo.TBL_INFO WHERE PORT_NUMBER=@PORT_NUMBER AND [ID]=@ID)=@PORT_NUMBER 
     BEGIN 
      If (SELECT [ID] FROM dbo.TBL_INFO WHERE [ID]=@ID)=@ID 
      BEGIN 

       UPDATE dbo.TBL_INFO 
        SET 
        dbo.TBL_INFO.ASSET_NUMBER = @ASSET_NUMBER, 
         dbo.TBL_INFO.MACHINE_NAME = @MACHINE_NAME, 
         dbo.TBL_INFO.PORT_NUMBER = @PORT_NUMBER, 
         dbo.TBL_INFO.BUILDING_NUMBER = @BUILDING_NUMBER, 
         dbo.TBL_INFO.ROOM_NUMBER = @ROOM_NUMBER, 
         dbo.TBL_INFO.TELEPHONE_NUMBER = @TELEPHONE_NUMBER, 
         dbo.TBL_INFO.[FLOOR]= @FLOOR, 
         dbo.TBL_INFO.TYPE = @TYPE, 
         dbo.TBL_INFO.BRANCH = @BRANCH, 
        dbo.TBL_INFO.[SECTION] = @SECTION, 
         dbo.TBL_INFO.USERS = @USERS, 
        dbo.TBL_INFO.[ID] = @ID, 
        dbo.TBL_INFO.SERIAL = @SERIAL 
           WHERE dbo.TBL_INFO.ASSET_NUMBER=@ASSET_NUMBER 
       INSERT INTO dbo.TBL_INFO (ASSET_NUMBER, MACHINE_NAME, PORT_NUMBER, BUILDING_NUMBER, ROOM_NUMBER, TELEPHONE_NUMBER, [FLOOR], TYPE, BRANCH, [SECTION], USERS, SERIAL, [ID]) VALUES (@ASSET_NUMBER, @MACHINE_NAME, @PORT_NUMBER, @BUILDING_NUMBER, @ROOM_NUMBER, @TELEPHONE_NUMBER, @FLOOR, @TYPE, @BRANCH, @SECTION, @USERS, @SERIAL, @ID) 
       SELECT @ID, ACCESS='VALID' 

      END 

       ELSE 
       BEGIN 
        SELECT @ID, ACCESS='INVALID' 
       END 
     END 

    ELSE 
     BEGIN 
      SELECT ACCESS='RESTRICTED' 
     END 
    END 
ELSE 
    BEGIN 
     SELECT ACCESS='DENIED'  
    END 
END 

GO

我要去哪里错了？

您从不执行命令！

你在所有的结尾需要这个的.AddWithValue（）调用：

cmd.ExecuteNonQuery();
