You can do this by building a dynamic sql statement.

-- Test data
declare @T table (F varchar(10))
insert into @T values
('Row 1'),
('Row 2'),
('Row 3'),
('Row 4'),
('Row 5')

-- String to hold dynamic sql
declare @S as varchar(max)
set @S = 'select '

--Build string
select @S = @S + quotename(F, '''') + ',' 
from @T
set @S = left(@S, len(@s)-1)

--Execute sql 
exec (@S)

Result

----- ----- ----- ----- -----
Row 1 Row 2 Row 3 Row 4 Row 5
