SQL Server: Function to get fiscal year or, session year

You can use this function to get the fiscal/financial year from a supplied date value. This may be useful when you have a datetime column in a table but you want to show it’s fiscal year. Another case when you may need this function is you have a datetime column in your table but you have to show the transaction made, specified fiscal year/session year wise or when you are preparing any statistical report.

 SELECT @SessYr= CASE WHEN DATEPART(MONTH,@SuppliedDate)>3 THEN CAST(DATEPART(YEAR,@SuppliedDate) AS VARCHAR(4))+'-'+RIGHT(CAST(DATEPART(YEAR,@SuppliedDate)+1 AS VARCHAR(4)),2) ELSE CAST(DATEPART(YEAR,@SuppliedDate)-1 AS VARCHAR(4))+'-'+RIGHT(CAST(DATEPART(YEAR,@SuppliedDate) AS VARCHAR(4)),2) END
 RETURN @SessYr

[Note: I have assumed the fiscal year as Indian fiscal year or, financial year. You can change it accordingly or, can use the below function]
