calculate fiscal year in sql select statement?

Question

I have a date field that needs to return in fiscal year format. example

Start_Date        Year 
04/01/2012 -      2013
01/01/2012 -      2012
09/15/2013 -            


        

Answer 1

I just chose to do it this way. It's easy and you can replace the 09,30 with whatever you want your fiscal year end to be. Not sure if this works in anything but SQL Server though.

CASE 
    WHEN CAST(GETDATE() AS DATE) > 
         SMALLDATETIMEFROMPARTS(DATEPART(YEAR,GETDATE()),09,30,00,000) 
    THEN 
        DATEPART(YEAR,GETDATE()) + 1 ELSE DATEPART(YEAR,GETDATE()) 
    END AS FY

Answer 2

David has a very good solution. A simpler expression is:

select year(dateadd(month, -3, start_date)) as FiscalYear

That is, subtract 3 months and take the year.

EDIT:

As noted in the comment, this seems to produce one year too early. Here are two solutions:

select year(dateadd(month, 9, start_date)) as FiscalYear

select 1 + year(dateadd(month, -3, start_date)) as FiscalYear

Answer 3

SELECT CASE WHEN DatePart(Month, Start_Date) >= 4
            THEN DatePart(Year, Start_Date) + 1
            ELSE DatePart(Year, Start_Date)
       END AS Fiscal_Year
FROM data

Answer 4

DECLARE @STARTDATE DATETIME, @ENDDATE DATETIME,@CURR_DATE DATETIME
SET @CURR_DATE='2015-01-30'
IF MONTH(@CURR_DATE) IN (1,2,3)
BEGIN
    SET @STARTDATE= CAST( CAST(YEAR(@CURR_DATE)-1 AS VARCHAR)+'/04/01'  AS DATE)
    SET @ENDDATE= CAST( CAST(YEAR(@CURR_DATE)  AS VARCHAR)+'/03/31'  AS DATE)
END
ELSE
BEGIN
    SET @STARTDATE= CAST( CAST(YEAR(@CURR_DATE) AS VARCHAR)+'/04/01'  AS DATE)
    SET @ENDDATE= CAST( CAST(YEAR(@CURR_DATE)+1 AS VARCHAR)+'/03/31'  AS DATE)
END
SELECT @STARTDATE AS ST_FI,@ENDDATE AS END_FY
