How to read the value of a certain column from the sqlite database, given its ID?

Question

Java

I tried through the cursor here is an example (sorry for the govnokoda I'm only learning)

//прочитать время
    public static long writeTime(String id) {
      Cursor c = mDB.query(DB_TABLE, new String[] {COLUMN_TIME},id, null, null, null, null, null);
      Log.d(TAG, "cursor = " + /*не конвертируется*/c);
      return 0;
