Question

I need a financial year entries based on current or today’s date AND time in Oracle11g DB.

Suppose if we consider today’s date is 1ST April 2013, then i need the outputs as 01-APR-13 and 31-MAR-14.

Our requirement financial Year considered is from April (the current year) to March (following year).

Based on current datetime…the scenario of output depends on the current date-time which falls in the above said period or duration.

Another example: If we take today’s datetime as 28th Dec 2012, then the output is needed as 01-APR-12 and 31-MAR-13.

Please help how to acheive the same in very short format using only SQL.

Consider the below table as

Create table venky (financialYearFrom DATE NOTNULL, financialYearTo DATE NOTNULL);

Something ugly:

   SELECT to_date('1-APR-'||(to_char(sysdate,'yyyy')+
                                (case when to_char(sysdate,'mm')>3 
                                 then 0 
                                 else -1 
                                 end))) AS start_date ,
      to_date('31-MAR-'||(to_char(sysdate,'yyyy')+
                                 (case when to_char(sysdate,'mm')>3 
                                  then 1 
                                  else 0 
                                  end))) end_date 
   FROM dual;

If month > 3 then add a year to 31-MAR(end_of_period), else substract a year to 1-APR (start_of_period).

UPDATE: Something nicer:

select add_months(trunc(add_months(sysdate,-3),'yyyy'),3) as start_date ,
    add_months(trunc(add_months(sysdate,-3),'yyyy'),15)-1 as end_date 
   from dual

Substracting 3 months will send you to the correct start year. Truncating to year and adding 3 months sends you to 1 APR. End_of period is 12 months ahead start minus one day.
