Answer 1

Hi,
To get the records between Previous Year First Day Same month to Current day..
SELECT TRUNC (ADD_MONTHS (SYSDATE, -12), 'MM') AS last_yr_first_date, TRUNC(SYSDATE) AS PRESENT_DATE
  FROM DUAL;Which Outputs to:
LAST_YR_FIRST_DATE     PRESENT_DATE
6/1/2011                   6/13/2012When you give TRUNC(sysdate) It will removes the Time part of the SYSDATE.
For Ex :
TRUNC(SYSDATE) means that is 6/13/2012 which doesn't give the time part in the query.
Which takes into account the day start that is from 12:00 A.M to today midnight 11.59 P.M.
And, One thing is that
emp sal Arrivaldate
111 200 03-mar-2011
100 200 03-mar-2008
150 200 06-mar-2012
170 200 03-mar-2003
178 200 03-mar-2004
112 200 12-jun-2012The arrivaldate is in Character format so you need to convert to date type as
SELECT TO_DATE(ARRIVALDATE,'DD-MON-YYYY') from your_table;
and the comparison can be done as
SELECT *
  FROM YOUR_TABLE
WHERE TO_DATE (ARRIVALDATE, 'DD-MON-YYYY')
   AND TRUNC (ADD_MONTHS (SYSDATE, -12), 'MM')
   AND TRUNC (SYSDATE);Good day!!!!!!!!!!!!!!!!!!!!!!!!
