select TRUNC(TO_DATE(sysdate),'YEAR'),
       (last_day(trunc(add_months(sysdate,-1)))) + 1 - (1/86400)
  from dual

TRUNC(TO_DATE(SYSDATE)-1,'YEAR')|(LAST_DAY(TRUNC(ADD_MONTHS(SYSDATE,-1))))+1-(1/86400)
1/1/2013|12/31/2012 11:59:59 PM

for results to the last day...

SELECT TRUNC(ADD_MONTHS(SYSDATE, -1), 'yyyy'), TRUNC(SYSDATE, 'mm') - 1 FROM DUAL


for results to the last second...

SELECT TRUNC(ADD_MONTHS(SYSDATE, -1), 'yyyy'), TRUNC(SYSDATE, 'mm') - 1/86400 FROM DUAL

simple verification code...


SELECT d, TRUNC(ADD_MONTHS(d, -1), 'yyyy'), TRUNC(d, 'mm') - 1 / 86400
  FROM (SELECT     ADD_MONTHS(TO_DATE('20120615', 'yyyymmdd'), LEVEL) d
              FROM DUAL
        CONNECT BY LEVEL <= 24)

Post here that talks about finding dates based upon current / previous / next value of year, month etc.
http://programmerslounge.blogspot.com/2011/07/how-to-get-first-day-and-last-day-of.html

You seem to always need the first day of the year represented by the previous month
If you're in January, you want the 1st day of the query to be January 1 of the previous year:

select TRUNC(ADD_MONTHS(SYSDATE, -1) , 'Year') from dual;

That would give you midnight of the first day of the year.

To get the last day of the previous month at 23:59:59 you could take the first day of the current month -1 second:

select TRUNC(SYSDATE , 'Month')-1/86400 from dual;

Running those two queries today (Jan 8, 2013) I get

2012-01-01 00:00:00
2012-12-31 23:59:59

yes, adjust the verification query to test whatever dates you want


it will correctly handle leap years too

select * from yourtable where datefield between
decode(to_char(sysdate,'mm'),'01',trunc(add_months(sysdate,-1),'yyyy'),trunc(sysdate,'yyyy')) and trunc(sysdate,'mm') -1/86400
from dttbl;

Didn't mean to copy "from dttbl;" (my test table)

select * from yourtable where datefield between
decode(to_char(sysdate,'mm'),'01',trunc(add_months(sysdate,-1),'yyyy'),trunc(sysdate,'yyyy')) and trunc(sysdate,'mm') -1/86400;

why the decode?  

trunc(add_months(sysdate,-1),'yyyy')


from my original post is sufficient for all months
try the verification code in my second post to confirm

I was a little late noticing it wasn't necessary and didn't bother changing since your solution had already been accepted by the time I posted :-)
