Jika ID=001 data baru akan insert ke table dan jika ID=001 sudah maka update qty bertambah

disini saya punya masalah bagaimana caranya jika terdapat data baru makan akan insert ke table dan jika data sudah ada maka akan upadate

contoh tblscan (ID,nmbrg,QTY)

jika data baru ID=001, nmbrg= A, QTY=1 maka insert ke tblscan

dan jika data ID=001 sudah ada dan saya input QTY jadi 2, maka akan update QTY nya saja berubah jadi 3.

dan jika saya input ID=002 maka akan jadi data baru insert lagi

terimakasih sblmnya

berikut yang sudah saya kerjakan

qty.setOnKeyListener(new View.OnKeyListener() {
    @Override
    public boolean onKey(View view, int keycode, KeyEvent keyEvent) {
        if ((keyEvent.getAction() == KeyEvent.ACTION_DOWN) && (keycode == KeyEvent.KEYCODE_ENTER)) {
            SQLiteDatabase db = controller.getWritableDatabase();
            cursor = db.rawQuery("select * from tblscan", null);
            if  (cursor != null && cursor.getCount() > 0)  {
                IDupdate = ID.getText().toString();
                qtyupdate = qty.getText().toString();
                db.execSQL("update tblscandata set QTY = QTY + '" + qty.getText().toString() + "' where ID = '" + IDupdate + "'");
               kosongdata();
            }
            else {
                IDinsert = ID.getText().toString();
                desinsert = desc.getText().toString();
                qtyinsert = qty.getText().toString();
                query_insert = "INSERT INTO " + DBController.tableName1 + " values ( '" + IDinsert +"', '" + desinsert + "','" + qtyinsert + "')";
                db.execSQL(query_insert);
                Toast.makeText(ScanData.this,"Data Inserted Successfully", Toast.LENGTH_LONG).show();
                kosongdata();
            }
        }
        return false;
    }

});

<div>Di baris kode ini:</div><pre>cursor = db.rawQuery("select * from tblscan", null);</pre><div>Diganti dengan:</div><pre>nomorID = ID.getText().toString(); cursor = db.rawQuery("select * from tblscan where ID='"+nomorID+"'", null);</pre><div>Jadi ID dari awal sudah dicari, bukan dibedakan IDupdate dan IDinsert. des dan qty jg harusnya gak perlu dibedain variabelnya, karena kan sumbernya sama2 dari TextField, malah bikin boros memori. Di baris kode ini:</div><pre>db.execSQL("update tblscandata set QTY = QTY + '" + qty.getText().toString() + "' where ID = '" + IDupdate + "'");</pre><div>Kenapa qty nya jadi string? Tapi di coba dulu aja, kalo error atau gak mau update, mungkin petiknya perlu dihilangin.</div><div> Kunjungi juga <a href="https://warkop-it.000webhostapp.com">https://warkop-it.000webhostapp.com</a></div>
