restructure sql

HI All,

select * from table where emplid ('1','2,'7') and date between to_date('01-OCT-2015') AND to_date('2-OCT-2015')

emplid  hours_worked date

2       8            01-OCT-2015

2       6            02-OCT-2015

it ignores the emplid 1 and 7 since no entries ,i want the data to be in the below format,

emplid  hours_worked date

1       null        01-OCT-2015

1       null        02-OCT-2015

2         8         01-OCT-2015

2         6         02-OCT-2015

7       null        01-OCT-2015

7       null        02-OCT-2015

note i have more than 100 emplid to pass in the IN clause and  i cant filter it other than passing to IN clause ,please let me know if there is any way to restructure this sql.
