Android: How can I search data in sqlite database

Time:09-07

I making project that user can scanning a barcode. My problem is, if the scanning results are the same as the kode_obat column, then the nama_obat, and harga_jual columns will be displayed or setText to Textview.

Please help me, How should I code ?

Here my Code :

MyDatabaseHelper.class

private Context context;
private static final String DATABASE_NAME = "Apotek.db";
private static final int DATABASE_VERSION = 1;

private static final String TABLE_NAME = "obat";
private static final String COLUMN_ID = "_id";
private static final String COLUMN_KODEOBAT = "kode_obat";
private static final String COLUMN_NAMAOBAT = "nama_obat";
//private static final String COLUMN_NOBATCH = "no_batch";
private static final String COLUMN_DISTRIBUTOR = "distributor";
private static final String COLUMN_EXPIRED = "expired_obat";
private static final String COLUMN_SATUAN = "satuan";
private static final String COLUMN_HARGASATUAN = "harga_satuan";
private static final String COLUMN_HARGAJUAL = "harga_jual";
private static final String COLUMN_PRODUSEN = "produsen";
//private static final String COLUMN_STOK = "stok_obat";
//private static final String COLUMN_HARGAOBAT = "harga_obat";

CodePudding user response:

to do the search in the database thing you will need to add this code.

SQLiteDatabase database = new MyDatabaseHelper(context).getReadableDatabase();
@SuppressLint("Recycle") Cursor cursor = database.rawQuery("SELECT "   
       MyDatabaseHelper.COLUMN_NAMAOBAT   " , "   MyDatabaseHelper.COLUMN_HARGAJUAL  " FROM "   MyDatabaseHelper.TABLE_NAME   " WHERE "   MyDatabaseHelper.COLUMN_KODEOBAT    " = '"   YOUR_TEXT_HERE  "'", null);
if(cursor.getCount()>0){
      cursor.moveToFirst();
      YOUR_TEXTVIEW1.setText(cursor.getString(0));  
      YOUR_TEXTVIEW2.setText(cursor.getString(1));
        
}
else{
      DO_YOUR_CODE_HERE

}

I hope this will help.

And you didn't have to post all of the code just a small sample, Actually, in your case, you don't have to post any of this.
