-I have a main activity with an arrayList where you can add diferent orders, my problem is when Iwant to click on to see this order the app close. I think that the error comes from The code from the SQLite database that it is this:

 public Comanda veureComanda (int id){
        DbHelper dbHelper = new DbHelper(context);
        SQLiteDatabase db = dbHelper.getWritableDatabase();

    Comanda comanda = null;
    Cursor cursorComanda = null;

    cursorComanda = db.rawQuery("SELECT * FROM "   TABLE_COMANDA   " WHERE id = "   id   "LIMIT 1", null);

    if (cursorComanda.moveToFirst()){
        comanda = new Comanda();
        comanda.setId(cursorComanda.getInt(0));
        comanda.setNom(cursorComanda.getString(1));
        comanda.setComanda(cursorComanda.getString(2));
        comanda.setUbicació(cursorComanda.getString(3));
    }

    cursorComanda.close();

    return comanda;
}

CodePudding user response：

there is no gap between '4' and 'LIMIT' keyword the correct request:

SELECT * FROM t_comanda WHERE id = 4 LIMIT 1
