數據庫未更新

我創建了一個將上傳圖像的頁面。當我點擊「上傳」時，沒有錯誤，這就是爲什麼我認爲圖像已經存儲在我的數據庫中。但沒有成功。數據庫沒有更新......數據庫未更新

這裏是我的代碼：

<%@ Import Namespace="System" %> 
<%@ Import Namespace="System.Data" %> 
<%@ Import Namespace = "System.Data.SqlClient" %> 
<%@ Import Namespace= "System.Data.OleDb" %> 


<script runat="server" type="text/c#"> 
protected void btnUpload_Click(object sender, EventArgs e) 


{ 
    { 
    byte[] imageSize = new byte 
       [FileUpload1.PostedFile.ContentLength]; 
    HttpPostedFile uploadedImage = FileUpload1.PostedFile; 
    uploadedImage.InputStream.Read 
    (imageSize, 0, (int)FileUpload1.PostedFile.ContentLength); 
// Create SQL Connection 
    OleDbConnection con = new OleDbConnection(); 
    con.ConnectionString = ConfigurationManager.ConnectionStrings["recordsConnectionString"].ConnectionString; 
// Create SQL Command 
OleDbCommand cmd = new OleDbCommand(); 
cmd.CommandText = "INSERT INTO PendingRecords(Image)" + 
        " VALUES (@Image)"; 
cmd.CommandType = CommandType.Text; 
cmd.Connection = con; 

OleDbParameter UploadedImage = new OleDbParameter 
       ("@Image", OleDbType.VarBinary, imageSize.Length); 

UploadedImage.Value = imageSize; 
cmd.Parameters.Add(UploadedImage); 
con.Open(); 
GridView1.DataSourceID = ""; 
GridView1.DataSource = SqlDataSource1; 
GridView1.DataBind(); 
con.Close();

你有沒有執行的創建與參數查詢？按我發現你缺少下面要做的事：

cmd.Parameters.Add(UploadedImage); 
con.Open(); 
cmd.ExceuteNonQuery(); /// you forgot this here.. 
GridView1.DataSourceID = "";

從@Remou評論：

圖片是一個保留字，所以加上括號「INSERT INTO PendingRecords（[圖片]）

謝謝，是的，我忘記了這一行，但我收到了新的錯誤「INSERT INTO語句中的語法錯誤。」異常詳細信息：System.Data.OleDb.OleDbException：INSERT INTO語句中的語法錯誤。我的代碼:)請 –

圖像是[保留字]（http://support.microsoft.com/kb/321266），所以添加括號'「INSERT INTO PendingRecords（[Image]）」' – Fionnuala
