Get current and previous Fiscal year start date and end date in SQL Server

  • Article

Recently, a user requested to develop a report. Report was the production of current and previous year.

Requirement was

  • User will input any random date.
  • Based on that date the report should display the production of current fiscal year as well as previous fiscal year.

Task was little bit difficult because you have to get current as well previous fiscal year dates from the given input date. To accomplish that task a SQL function was created.

This might helpful to others.

Comments and corrections are welcome.
