I have a problem on my hand. I am working on an application where user wants to send the wish cards to his clients whose birthday is within user provided FROM and TO date , irrespective of the year. I.e. the search results should be on the basis of the Month and date only. e.g my input parameteres are from date: “12/05” (December 05)and To Date: “01/04” (January 04). Please help. Thanks in advance

    You should use this query condition. It selects birthdate if it is in one month interval from now. Birthdate can be from any year:

    where
TO_DATE(TO_CHAR(birthdate,'dd.mm')||'.1900','DD.MM.YYYY') ,
between
TO_DATE(TO_CHAR(sysdate,'dd.mm')||'.1900','DD.MM.YYYY') 
and ADD_MONTHS(TO_DATE(TO_CHAR(sysdate,'dd.mm')||'.1900','DD.MM.YYYY'),1)

    If user inputs date range as for example ’02/03′ and ’23/06′ (‘P1’ and ‘P2’ in this query) then use following condition. 

    where
(
TO_DATE(TO_CHAR(birthdate,'dd.mm')||'.1900','DD.MM.YYYY') ,
between
TO_DATE('P1'||'.1900','DD.MM.YYYY') 
and
TO_DATE('P2'||'.1900','DD.MM.YYYY') 
)

OR
(
    (TO_DATE('P1'||'.1900','DD.MM.YYYY') 
        > TO_DATE('P2'||'.1900','DD.MM.YYYY') )
    and 

    (
     TO_DATE(TO_CHAR(birthdate,'dd.mm')||'.1900','DD.MM.YYYY') ,
     between
     TO_DATE('P1'||'.1900','DD.MM.YYYY') 
     and
     TO_DATE('31.12.1900','DD.MM.YYYY') 
     OR
     TO_DATE(TO_CHAR(birthdate,'dd.mm')||'.1901','DD.MM.YYYY') ,
     between
     TO_DATE('01.01.1901','DD.MM.YYYY') 
     and
     TO_DATE('P2'||'.1901','DD.MM.YYYY') 


    )
