當我從主要活動傳遞到另一個活動時，我的應用程式關閉-有解無憂

錯誤：

E/SQLiteLog: (1) unrecognized token: "4LIMIT" in "SELECT * FROM t_comanda WHERE id = 4LIMIT 1"

-我有一個帶有 arrayList 的主要活動，您可以在其中添加不同的訂單，我的問題是當我想單擊以查看此訂單時應用程式關閉。我認為錯誤來自 SQLite 資料庫中的代碼，它是這樣的：

 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;
}

uj5u.com熱心網友回復：

'4' 和 'LIMIT' 關鍵字之間沒有間隙正確的請求：

SELECT * FROM t_comanda WHERE id = 4 LIMIT 1
