In my table I have some columns and from them I want to retrive those rows that satisfy the condition of data in 2 columns namely, 'TX_ID' and 'TX_DATE'. If the value in TX_ID is "E" and if the date in TX_DATE is todays date then I want those rows. In the following code I use '&&' and 'AND' at the where clause of cursor query but no use. The value "E" is in String 'name' and the today date is in String 'td'.
Can anyone help me out?

String td= new SimpleDateFormat("dd-MM-yyyy").format(new Date());
  String name="E";
  SQLiteDatabase db =    helper.getReadableDatabase();

  String[] columns = {VivzHelper.UID, helper.TX_NAME, helper.TX_PARTICULARS, helper.TX_AMOUNT,helper.TX_DATE}; // from tx_table..tested ok
  Cursor c = db.query( VivzHelper.TX_TABLE, columns, (helper.TX_ID + "='" + name + "'") AND (helper.TX_DATE + "='" + td + "'"), null, null, null, null, null);
  if (c != null) {
      c.moveToFirst();
  }
  return c;
