Where is your date coming from? Is it a column in your table? Are you using SQL Server? SELECT 'QQ' + cast(YEAR(GETDATE()) as varchar) + cast(MONTH(GETDATE()) as varchar) + REPLICATE('0' 4 - LEN(Id)) + cast(Id as varchar) From Tickets Replace GETDATE() with your date column.

If it is not an identity you could write a trigger that checks if the date has changed and reset the value. I am not sure that you could solve this with just an identity column.
