我一直在尝试使用SQLite创建一个简单的登录表单，但是当我运行这个程序时，它总是给我带来一个关于da.Fill（dt）的错误;

if (txtUserN.Text.Trim() == "" && txtPass.Text.Trim() == "")
            {
                MessageBox.Show("fucken");
            }
            else
            {
                string query = "SELECT * FROM Customers WHERE User Name= @username AND Password = @password";
                SQLiteConnection conn = new SQLiteConnection(@"Data Source=C:\Users\Benjamin\OneDrive\Documents\School Shit\Assignments\ass\chan chan chan\chan chan chan\bin\ddoocp.db");
                conn.Open();
                SQLiteCommand cmd = new SQLiteCommand(query, conn);
                cmd.Parameters.AddWithValue("@User Name", txtUserN.Text);
                cmd.Parameters.AddWithValue("@Password", txtPass.Text);
                SQLiteDataAdapter da = new SQLiteDataAdapter(cmd);
                DataTable dt = new DataTable();
                da.Fill(dt);

                if (dt.Rows.Count > 0)
                {
                    MessageBox.Show("Login Successful");
                }

System.Data.SQLite.SQLiteException:'“名称”附近出现SQL逻辑错误：语法错误'
