Hi,

You can't ask the database to update the value at the end of month. Instead write a program and then run it at 31st December 12.00am and then execute the following query:

update leave_balance set newcolumn=leave balance;

You can also run the program through Quartz scheduler or cron job scheduler.

Thanks
