Error Code : 1 (SQLITE_ERROR) Android

Question

I don't understand this error:

Caused By : SQL(query) error or missing database. (no such table: evaluation (code 1): , while compiling: SELECT _id, evaluation_subject, weight, mark, course_id FROM evaluation)

EvaluationDAO.java

    };

    public EvaluationDAO(Context context){
        dbHelper = new DBHelper(context);
        this.context = context;

        try{
            open();
        } catch(SQLException e){
            Log.e(TAG, "SQLException on openning database " + e.getMessage());
            e.printStackTrace();
        }
    }

    public void open() throws SQLException{
        database = dbHelper.getWritableDatabase();
    }

    public void close(){
        dbHelper.close();
    }
public ArrayList<Evaluation> getAllEvaluations(){
        ArrayList<Evaluation> listEvaluation = new ArrayList<Evaluation>();

        Cursor cursor = database.query(DBHelper.TABLE_EVALUATIONS, allColumns, null, null,
                null, null, null);

        cursor.moveToFirst();
        while (!cursor.isAfterLast()){

            cursor.moveToNext();
        }


        cursor.close();
