Period Logic

Question

Hi I have requirement below,
In the standard way the application includes the transaction values that belong to the calendar associated to the SOB. In Colombia, the 1st SOB has associated the corporate Fiscal Calendar (APR-MAR) and legally is necessary in Colombia detail all the information using the Annual Calendar (JAN-DEC).
SELECT A.Period_num,
A.PERIOD_NAME,A.PERIOD_YEAR,A.START_DATE,A.END_DATE,A.* FROM GL_PERIODS A
WHERE A.PERIOD_SET_NAME = 'BT CALENDAR'
AND A.PERIOD_TYPE ='1'
AND ( a.period_year = 2010 AND a.period_num BETWEEN :p_period_start AND :p_period_end-3 or a.period_year = 2009 AND a.period_num BETWEEN 10 AND 12) --) OR
--(a.period_year = 2009 AND a.period_num BETWEEN : p_period_start AND :p_period_end)
AND A.ADJUSTMENT_PERIOD_FLAG <>'Y'
This works fine when user enter with the range Period num 1 to 12,But it does not work with some scenarios like 1 to 1,etc.........
Can any one help me in this regard?

Hi,
Please don't post unformatted code.
You shouldn't even write unformatted code, but if you want to spend your time trying to read it, nobody can stop you. However, when you ask people on this forum for help, don't ask them to read that mess.
When posting code, or any formatted text, on this site, type these 6 characters
\(all small letters, inside curly brackets) before and after each section of formatted text.
If you format your code, one possible error becomes very clear:SELECT A.Period_num,
     A.PERIOD_NAME,
     A.PERIOD_YEAR,
     A.START_DATE,
     A.END_DATE,
     A.*
FROM     GL_PERIODS          A
WHERE     A.PERIOD_SET_NAME     = 'BT CALENDAR'
AND      A.PERIOD_TYPE          = '1'
AND     (      a.period_year     = 2010
     AND     a.period_num     BETWEEN     :p_period_start
                    AND     :p_period_end - 3
     or     a.period_year     = 2009
     AND     a.period_num     BETWEEN     10
                    AND      12
AND     A.ADJUSTMENT_PERIOD_FLAG     != 'Y'     -- Is this what you meant?
You are mixing AND and OR operators.  You whould never do that; always add parentheses so that the ANDs and ORs are separated.
Perhaps this is what you meant:AND     (      (     a.period_year     = 2010
          AND     a.period_num     BETWEEN     :p_period_start
                         AND     :p_period_end - 3
     or     (     a.period_year     = 2009
          AND     a.period_num     BETWEEN     10
                         AND      12
Another possible problem is that the right-operands to BETWEEN should be in order.  Perhaps you need to say:...          AND     a.period_num     BETWEEN     :p_period_start
                         AND     GREATEST ( :p_period_end - 3
                                   , :p_eriod_start
I hope that solves your problem.
If not, post a little sample data (CREATE TABLE and INSERT statements), a couple of sets of parameters (:p_period_start and :p_period_end) and the results (formatted) that you want from the sample data for each set of parameters.
