Pass data from one query to another activity, listview

I asked a question about how to pass data between activities, and they answered me well, but my problem now is that I do not need to pass a simple string or an integer, I need to pass a query SQLserver, put it in the intent and then pass it to the other activity to show me there, but I do not know how to do it, passing plain text is easy, but I do not understand what to do with a SQLserver query, I've been trying for a while and I can not, can someone give me a cable? I leave the code here, thank you!

public class Listado extends AppCompatActivity {
ListView listView;
TextView idtext;
EditText etFiltrar;
String where = "";


@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_listado);
    setupActionBAR();
    etFiltrar = (EditText) findViewById(R.id.etFiltrrar);

    etFiltrar.addTextChangedListener(new TextWatcher() {
        @Override
        public void beforeTextChanged(CharSequence s, int start, int count, int after) {
        }

        @Override
        public void onTextChanged(CharSequence s, int start, int before, int count) {
            where = etFiltrar.getText().toString();
            mostrarClientes();
        }

        @Override
        public void afterTextChanged(Editable s) {
        }
    });
    listView = (ListView) findViewById(R.id.lvMostrar);
    listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
            ViewGroup vg = (ViewGroup) view;
            idtext = (TextView) vg.findViewById(R.id.id);
            Log.i("Click", position + " " + idtext.getText());
            // ESTO SOLO MUESTRA UN TOAST CON LA POSITION + ID DE TABLA
            //  Toast.makeText(getApplicationContext(), "Position= " + position + " ID=" + idtext.getText().toString(), Toast.LENGTH_SHORT).show();
            **enviardatos()**;
        }
    });
    mostrarClientes();
}

public void **enviardatos**() {
    **//Pr**ocedimiento para poder pasarlo a la otra activity, aquí tendría que meter los datos de la consulta sql pero no se como..
    Intent intent = new Intent(Listado.this, ClienteEspecifico.class);
    intent.putExtra("nombre", "**CADENA SIMPLE, PERO QUIERO PASAR UNA CONSULTA** SQL");
    startActivity(intent);
}

private void setupActionBAR() {
    ActionBar actionBar = getSupportActionBar();
    if (actionBar != null) {
        //Mostrar el boton en el ActionBar
        actionBar.setDisplayHomeAsUpEnabled(true);
        actionBar.setTitle("Lista de Clientes");
    }
}

public void mostrarClientes() {
    HashMap<String, String> clientes = new HashMap<>();
    ConectarHaciaSQL consql;
    consql = new ConectarHaciaSQL();
    Connection cn = consql.conexionBD();

    try {
        Statement pst = cn.createStatement();
        String sel;
        sel = "select CLI.idcliente, CLI.NombreComercial, UC.telefono1 from clientes as CLI" + " left join ubicacionesClientes as UC on UC.idcliente = CLI.idCliente ";
        if (where != "") {
            sel = sel + " where CLI.NombreComercial like '%" + where + "%'";
        }
        //sel = sel + " ORDER BY CLI.idcliente ASC";
        //Ejecuta el query del SQL
        ResultSet rs = pst.executeQuery(sel);
        //Recorre la tabla del SQL
        while (rs.next()) {
            clientes.put(rs.getString(1), rs.getString(2));//
        }

        if (rs != null) {
        } else
            Toast.makeText(getApplicationContext(),
                    "No hay nada ", Toast.LENGTH_LONG).show();
        if (rs != null)
            rs.close();

        List<HashMap<String, String>> listItems = new ArrayList<>();
        SimpleAdapter adapter = new SimpleAdapter(this, listItems, R.layout.list_items,
                new String[]{"First Line", "Second Line"},
                new int[]{R.id.id, R.id.name});

        Iterator it = clientes.entrySet().iterator();
        while (it.hasNext()) {
            HashMap<String, String> resultMap = new HashMap<>();
            Map.Entry pair = (Map.Entry) it.next();
            resultMap.put("First Line", pair.getKey().toString());
            resultMap.put("Second Line", pair.getValue().toString());
            listItems.add(resultMap);
        }
        listView.setAdapter(adapter);

    } catch (SQLException e) {
        Log.i("Error", "Error al abrir o crear la base de datos" + e);
    }
}

}

How do you see I have an SQL query that shows names in a listview, but now I need another query, (I guess) as I said, show for example name, phone and some more data in a textview of another activity , or to be able to be each one in an EditText, if someone answers me well I will love him. Thanks !!!

I add the other activity where I want to collect the new data.

public class ClienteEspecifico extends AppCompatActivity {
TextView tvMostrarDatos;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_cliente_especifico);
    tvMostrarDatos = (TextView) findViewById(R.id.tvMostrarDatos);
    setupActionBAR();
    Bundle bundles = getIntent().getExtras(); //En este objeto es donde están los datos que hemos enviado, pero esto es una cadena simple, necesito la consulta

    String nombre = bundles.getString("nombre");
    //  Integer telefono = bundles.getInt("telefono");
    tvMostrarDatos.setText(nombre);
    //tvMostrarDatos.setText(telefono);

}

}
