Join не работает с connect by
Например, построим отчет в котором укажем сотрудника и его непосредственного начальника:
SELECT
LPAD(' ', (LEVEL - 1) * 2) // A.NAME AS Н_NAME,
B.NAME AS BOSS_NAME
FROM EMPL A, EMPL B
WHERE A.PARENT_ID = B.ID( )
CONNECT BY PRIOR A.ID = A.PARENT_ID
START WITH A.ID = 1;На старых версиях Oracle, можно получить сообщение об ошибке:
ERROR at line 4:ORA-01437: cannot have join with CONNECT BY
Обойти эту проблему можно создав представление:
CREATE OR REPLACE VIEW V_EMPL
AS
SELECT
LPAD(' ', (LEVEL - 1) * 2) // NAME AS H_NAME,
ID,
PARENT_ID,
LEVEL AS THE_LEVEL
FROM EMPL
CONNECT BY PRIOR ID = PARENT_ID
START WITH ID = 1;Колонку LEVEL переименовали, чтобы представление не заканчивалось на зарезервированное слово.
SQL> SELECT * FROM V_EMPL;
Сейчас можно выполнить JOIN
SELECT A.H_NAME, B.NAME AS BOSS_NAME FROM V_EMPL A, EMPL B WHERE A.PARENT_ID = A.ID( );
Если обратите внимание, то увидите что выполнено OUTER JOIN, потому что в списке нет большого босса.

Oracle queries with lpad and rpad
The documentation, oddly, does not state what the return value of LPAD is when the first argument is null. As you found out, the return is null in that case.
The third argument must be of some character data type. You are passing 0, which Oracle will big-brother-rly convert to the string ‘0’. But that’s not what you want anyway.
The correct way to generate a string of five spaces is, as Kaushik Nayak showed in another answer already: lpad(' ', 5). The default for the third argument is space, so you don’t need to add it.
However, the simplest answer for your entire query is to lpad the result of rpad, like so:
select lpad( rpad(city_name, 20) , 25 ) from ....
Now the city name is right-padded to length 20, and the result gets five spaces prepended (to make the length increase from 20 to 25).
To make it easier for future developers, you may even write 20 5 instead of 25 — to make it clear the intent was to add five more characters (which by default are spaces) to the left (Lpad) of the result of RPAD.

Returns
The RPAD function returns a string value.
Подзапросы, списки и connect by
Вместо VIEW и JOIN можно использовать вложенные запросы в списке выборки:
SELECT
LPAD(' ', (LEVEL - 1) * 2) // NAME AS H_NAME,
(SELECT NAME
FROM EMPL B
WHERE B. ID = A.PARENT_ID) AS BOSS_NAME
FROM EMPL A
CONNECT BY PRIOR ID = PARENT_ID
START WITH ID = 1;
H_NAME BOSS_NAME

Для увеличения производительности, вам потребуется создать индексы на таблицу, которые позволят Oracle быстрее получать ответ на вопрос, «кто является детьми некого родителя Х?»:
CREATE INDEX EMPL_IDX1 ON EMPL (ID, PARENT_ID); CREATE INDEX EMPL_IDX2 ON EMPL (PARENT_ID, ID);
