我有一张表,我需要更新用户密码,其中用户名存储在会话中。但是,我收到此错误:“操作必须使用可更新的查询”,即使我已授予所有用户和管理员完全控制权。

以下是我的代码:

string str = @"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\inetpub\wwwroot\myfolder\mydatabase";
using (OleDbConnection con = new OleDbConnection(str))
using (OleDbCommand cmd = con.CreateCommand())
{
    cmd.CommandText = "UPDATE [users] SET [password] = ? WHERE username = ?";
    cmd.Parameters.Add("password", OleDbType.VarChar).Value = Request.Form["conPassword"];
    cmd.Parameters.Add("username", OleDbType.VarChar).Value = (string)Session["username"];
    con.Open();
    try
    {
         cmd.ExecuteNonQuery();
         MessageBox.Show("Your password has been changed successfully.");
    }
    catch (Exception ex)
    {
         Response.Write(ex.Message);
    }
    finally
    {
         con.Close();
    }
}
