select isComplete from task where taskid in (1,2)

taskid isComplete
1 0

2 1

I want the output of the query such as
i should be able to use bitwise operation on column 'isComplete' (in row values)
for row 1 value and row 2 value.

I can not use query like
select (select isComplete from task where taskid=1) &
(select isComplete from task where taskid=2)

as parameters can vary each time like taskid in (1,2,3) also.

How to manage it?

DECLARE @Ret int
SELECT @Ret=COALESCE(@Ret,1) & isComplete
FROM YourTable 
WHERE taskid in (1,2,3) 
SELECT @Ret
