This might be Old and 'Outdated' version of Puzzle but might be enough to rise some sort of curiosity.
This puzles is about to create a calendar representation of given month in given year in rows and columns like
SQL> /
SU MO TU WE TH FR SA
-- -- -- -- -- -- --
-- -- 01 02 03 04 05
06 07 08 09 10 11 12
13 14 15 16 17 18 19
20 21 22 23 24 25 26
27 28 29 30 31 -- --
In case Input is '01' for month and '2008' for year .
Have a nice Luck !!!
[Please add this to sticky Puzzle , if it is found interesting ]
Rajuvan.
[Edit MC: change Z^001 to number and add complexity rate, please Rajuvan do it yourself next time]

As there are many ways to do it and already published in PL/SQL, I will provide a new one fully in SQL.
SQL> Def month=11
SQL> Def year=1956
SQL> alter session set nls_territory=AMERICA nls_date_language=AMERICAN;
SQL> Set feed off
SQL> Set head off
SQL> Def month=11
SQL> Def year=1956
SQL> Col line format a50
SQL> Col nop noprint
SQL> With
2 -- days: 1 line per week day
3 days as ( select level day from dual connect by level <= 7 ),
4 -- weeks: 1 line per possible week in a month
5 weeks as ( select level-1 week from dual connect by level <= 6 ),
6 -- mdays: each day of the month within each week
7 mdays as (
8 select week, weekday,
9 case
10 when day > to_char(last_day(to_date('&Month/&Year','MM/YYYY')),'DD')
11 then ' '
12 when day <= 0 then ' '
13 else to_char(day,'99')
14 end monthday
15 from ( select week, day weekday,
16 7*week+day-to_char(to_date('&Month/&Year','MM/YYYY'),'D')+1 day
17 from weeks, days
18 )
19 )
20 -- Display blank line
21 select 0 nop, null line from dual
22 union all
23 -- Display Month title
24 select 1 nop,
25 to_char(to_date('&month/&year','MM/YYYY'),' FMMonth YYYY') line
26 from dual
27 union all
28 -- Display blank line
29 select 2 nop, null line from dual
30 union all
31 -- Display week day name
32 select 3 nop,
33 sys_connect_by_path(substr(to_char(trunc(sysdate,'D')+day-1,'Day'),
34 1,3),' ') line
35 from days
36 where day = 7
37 connect by prior day = day-1
38 start with day = 1
39 union all
40 -- Display each week
41 select 4+week nop, replace(sys_connect_by_path(monthday,'/'), '/', ' ') line
42 from mdays
43 where weekday = 7
44 connect by prior week = week and prior weekday = weekday-1
45 start with weekday = 1
46 order by 1
47 /
November 1956
Sun Mon Tue Wed Thu Fri Sat
1 2 3
4 5 6 7 8 9 10

18 19 20 21 22 23 24
25 26 27 28 29 30
What is interesting is that whatever is your country, the query always displays the calendar with the first day of week for you in the first column (Lundi is Monday in French):
SQL> alter session set nls_territory=FRANCE nls_date_language=FRENCH;
47 /

26 27 28 29 30
SQL> alter session set nls_territory=IRAQ nls_date_language=AMERICAN;

I thought i would try it myself. This is not as international as Michael's, but it is much simpler.
Year and Month is put in the WITH:
WITH
Data
AS
(
SELECT
TO_DATE('200811', 'YYYYMM') YM
FROM
Dual
)
SELECT
CASE WHEN D + 1 BETWEEN 1 AND LD THEN TO_CHAR(D + 1, 'FM09') ELSE '--' END SU,
CASE WHEN D + 2 BETWEEN 1 AND LD THEN TO_CHAR(D + 2, 'FM09') ELSE '--' END MO,
CASE WHEN D + 3 BETWEEN 1 AND LD THEN TO_CHAR(D + 3, 'FM09') ELSE '--' END TU,
CASE WHEN D + 4 BETWEEN 1 AND LD THEN TO_CHAR(D + 4, 'FM09') ELSE '--' END WE,
CASE WHEN D + 5 BETWEEN 1 AND LD THEN TO_CHAR(D + 5, 'FM09') ELSE '--' END TH,
CASE WHEN D + 6 BETWEEN 1 AND LD THEN TO_CHAR(D + 6, 'FM09') ELSE '--' END FR,
CASE WHEN D + 7 BETWEEN 1 AND LD THEN TO_CHAR(D + 7, 'FM09') ELSE '--' END SA
FROM
(
SELECT
EXTRACT(DAY FROM YM) - TO_CHAR(YM, 'D') + ((Level - 1) * 7) D,
EXTRACT(DAY FROM LAST_DAY(YM)) LD
FROM
Data
CONNECT BY
Level < = Level <= CEIL((EXTRACT(DAY FROM LAST_DAY(YM)) + TO_CHAR(YM, 'D') - 1) / 7)
);

I just realized i pasted that incorrectly. I don;t see an edit button, so i will post it again without the extra "LEVEL < =":
WITH
Data
AS
(
SELECT
TO_DATE('200811', 'YYYYMM') YM
FROM
Dual
)
SELECT
CASE WHEN D + 1 BETWEEN 1 AND LD THEN TO_CHAR(D + 1, 'FM09') ELSE '--' END SU,
CASE WHEN D + 2 BETWEEN 1 AND LD THEN TO_CHAR(D + 2, 'FM09') ELSE '--' END MO,
CASE WHEN D + 3 BETWEEN 1 AND LD THEN TO_CHAR(D + 3, 'FM09') ELSE '--' END TU,
CASE WHEN D + 4 BETWEEN 1 AND LD THEN TO_CHAR(D + 4, 'FM09') ELSE '--' END WE,
CASE WHEN D + 5 BETWEEN 1 AND LD THEN TO_CHAR(D + 5, 'FM09') ELSE '--' END TH,
CASE WHEN D + 6 BETWEEN 1 AND LD THEN TO_CHAR(D + 6, 'FM09') ELSE '--' END FR,
CASE WHEN D + 7 BETWEEN 1 AND LD THEN TO_CHAR(D + 7, 'FM09') ELSE '--' END SA
FROM
(
SELECT
EXTRACT(DAY FROM YM) - TO_CHAR(YM, 'D') + ((Level - 1) * 7) D,
EXTRACT(DAY FROM LAST_DAY(YM)) LD
FROM
Data
CONNECT BY
Level <= CEIL((EXTRACT(DAY FROM LAST_DAY(YM)) + TO_CHAR(YM, 'D') - 1) / 7)
);

another simple and not international one:
with t as (
select to_date('200811','yyyymm') ym from dual)
SELECT * FROM (
SELECT MIN (DECODE (TO_CHAR (YM + LEVEL - 1, 'd'), '1', LEVEL)) SUN
, MIN (DECODE (TO_CHAR (YM + LEVEL - 1, 'd'), '2', LEVEL)) MON
, MIN (DECODE (TO_CHAR (YM + LEVEL - 1, 'd'), '3', LEVEL)) TUE
, MIN (DECODE (TO_CHAR (YM + LEVEL - 1, 'd'), '4', LEVEL)) WED
, MIN (DECODE (TO_CHAR (YM + LEVEL - 1, 'd'), '5', LEVEL)) THU
, MIN (DECODE (TO_CHAR (YM + LEVEL - 1, 'd'), '6', LEVEL)) FRI
, MIN (DECODE (TO_CHAR (YM + LEVEL - 1, 'd'), '7', LEVEL)) SAT
FROM T
CONNECT BY LEVEL <= LAST_DAY (YM) - YM + 1
GROUP BY TRUNC (YM + LEVEL, 'iw'))

6 rows selected.
Maybe an ORDER BY is missing.

Good.. Nice and rare gintsp . Good search 
Let me add One more Alternative but in PL/SQL. Though outdated , I hope it will add the value to the thread.
I got it form Oracle link
create or replace procedure calendar(month varchar,year varchar) as type weeks
is varray(6) of varchar2(21);
l_weeks weeks := weeks();
l_last_day number;
l_w_day number;
begin l_weeks.extend(6);
l_w_day := to_number(to_char(to_date(month||year,'MMYYYY'),'D'));
l_last_day := to_number(to_char(last_day(to_date(month||year,'MMYYYY')),'DD'));
for i in 1..l_last_day loop
l_weeks(trunc((i+l_w_day-2)/7)+1) := l_weeks(trunc((i+l_w_day-2)/7)+1)||' '||rpad(to_char(i),2);
end loop;
dbms_output.put_line('----- '||month||'-'||year||' -----');
dbms_output.put_line('--------------------');
dbms_output.put_line('Su Mo Tu We Th Fr Sa');
dbms_output.put_line(lpad(l_weeks(1),20,'-'));
for i in 2..6 loop
dbms_output.put_line(l_weeks(i));
end loop;
dbms_output.put_line('--------------------');
end;
