Primary Key Custom Format

Question

Good Day to all,

 

Please help me with my project, I would like to create a Custom Primary Key in my database design,

the format is [current year][current month][3 digit counter].

This goes something like this ==> 201602001. Next id should be 201602002 and so on, but here is the catch, the following month it should display ==> 201603001 then next id should be 201603002 and so on. The three digit counter should reset to 001 every month. 

 

Is this possible? 

 

Thank you in advance....
