Visual Studio 数据库未更新

如何解决Visual Studio 数据库未更新

我正在处理一个学校项目，由于某种原因，尽管更改的行数不超过 0 并触发更新成功警报，但我的 mysql 数据库没有更新。它还设法仅从我的文件上传更新我的图像数据。

**admin_products_details_edit.aspx.cs**

protected void btn_ProdEdit_Click(object sender,EventArgs e)
        {
            int result = 0;
            string image = "";

            if (FileUpload_ProdImg.HasFile == true)
            {
                image = "images\\" + FileUpload_ProdImg.FileName;
                img_result.ImageUrl = FileUpload_ProdImg.FileName;
            }
            else 
            {
                image = img_result.ImageUrl;
            }
            
            Product Prod = new Product();
            string datProdID = lbl_ProdID.Text;
            string datProdName = tb_ProdName.Text;
            string datProdDesc = tb_ProdDesc.Text;
            string datProdImg = img_result.ImageUrl;
            decimal datProdPrice = decimal.Parse(tb_ProdPrice.Text);
            int datProdCal = int.Parse(tb_ProdCal.Text);
            int datStockLvl = int.Parse(tb_StockLvl.Text);
            result = Prod.ProductUpdate(datProdID,datProdName,datProdDesc,datProdImg,datProdPrice,datProdCal,datStockLvl);
            if (result > 0)
            {
                string saveimg = Server.MapPath(" ") + "\\" + image;
                FileUpload_ProdImg.SaveAs(saveimg);
                Response.Write("<script>alert('Update successful');</script>");
                Response.Redirect("admin_products_details.aspx?ProdID=" + datProdID);

            }
            else
            {
                Response.Write("<script>alert('Update fail');</script>");
            }
        }<-The code for the button edit event trigger

**Product.cs**
    ...public int ProductUpdate(string upID,string upName,string upDesc,string upImg,decimal upPrice,int upCal,int upstkLvl)
        {
            string queryStr = "UPDATE Products SET" + " ProdName = @productName," + " ProdDesc = @productDesc," + " ProdImg = @productImage," + " ProdPrice = @productPrice," + " ProdCalorie = @productCal," + " StockLevel = @productStkLvl " + " WHERE ProdID = @productID";

            SqlConnection conn = new SqlConnection(_connStr);
            SqlCommand cmd = new SqlCommand(queryStr,conn);
            cmd.Parameters.AddWithValue("@productID",upID);
            cmd.Parameters.AddWithValue("@productName",upName);
            cmd.Parameters.AddWithValue("@productDesc",upDesc);
            cmd.Parameters.AddWithValue("@productImage",upImg);
            cmd.Parameters.AddWithValue("@productPrice",upPrice);
            cmd.Parameters.AddWithValue("@productCal",upCal);
            cmd.Parameters.AddWithValue("@productStkLvl",upstkLvl);

            conn.Open();

            int nofRow = 0;
            nofRow = cmd.ExecuteNonQuery();

            conn.Close();

            return nofRow;
        }<-The code for updating the mysql database,located in a different cs file,titled Product.cs

我的mysql数据库表叫做Products
