Answer 1

May be you need something like that:

select to_char(add_months (to_date('10/18/2007','MM/DD/YYYY'), -1* Level), 'Mon-YYYY')
Month   
FROM Dual
CONNECT BY Level <= 11
order by month

Answer 2

YOU CAN USE THIS:

SELECT TO_CHAR( ADD_MONTHS(SYSDATE,-1*LEVEL  ),'MON') MONTH_NAME
    FROM DUAL
CONNECT BY LEVEL  <= MONTHS_BETWEEN(   TRUNC(SYSDATE,'MM')  , ADD_MONTHS( TRUNC(SYSDATE,'MM'),-11))
 ORDER BY LEVEL
