Attendance and Leave table Join

Syed KhawarAug 6 2012 — edited Aug 7 2012
Hi,
I want to join both of the following tables "Attendance" and "Leave", common key is EMP# = EMPLOYEE_NUMBER but the problem is that the Leave table stores range(start and end date) of leaves not daily record in this case how can I generate each day record from Leave table(where leaves defined as Start and End date) to join with Attendance table or any other solution anyone suggest.

Thanks & Regards,
Syed Khawar
