I have columns name, taskname start_date and end_date in my table.

Name Task StartDate EndDate
abc task1 2008-04-01 2008-04-03
abc task2 2008-04-05 2008-04-15
abc task3 2008-04-08 2008-04-18
abc task4 2008-04-21 2008-04-25
abc task5 2008-04-19 2008-04-23
abc task6 2008-04-25 2008-04-30

I need to find out the dates for which there are no tasks planned for the person in the month excluding Saturdays and Sundays.

Is it possible to get the output in a single SQL itself, or else how could it be done in PL/SQL procedure ?
