hi, utill now i always been using mysql for database, but i must learn some local faster database so i found sqlite, i dont know how sqlite works so thats why im here, basically i just made a quick database and i named it 'data.db', and now using c# i need to read the data that is inside but i read it like this:

SQLiteConnection m_dbConnection;
            m_dbConnection = new SQLiteConnection("Data Source=data.db;Version=3;");
            m_dbConnection.Open();

            string sql = "select Question from questions where QuestionID = 1;";
            SQLiteCommand command = new SQLiteCommand(sql, m_dbConnection);
            SQLiteDataReader reader = command.ExecuteReader();
            //while (reader.Read())
                txtResponse.Text = "1";
                //returnpoint = reader["Question"].ToString();
            //txtResponse.Text = returnpoint;

the sql command syntax is correct because i use the same in mysql.
but it shows problem, here is a picture for more info.
btw thanks in advance, also i forgot to mention that i have referenced "System.Data.SQLite.dll"
