estimate table spaces

hi guys,
sp_spaceused 'table1'
I have two ntext columns in 'table1',
by default, is sp_spaceused calculating space for ntext too?Hi Britney
All columns are included. You can see this for yourself:
use pubs
go
select * into newtitles from titles
go
exec sp_spaceused newtitles, @.updateusage= true
go
alter table newtitles add info ntext
go
update newtitles set info = replicate(title, 100)
go
exec sp_spaceused newtitles, @.updateusage= true
go

LOB data (type text, ntext and image) is by default stored on separate pages
outside the data rows. As soon as you update any rows with LOB data to
anything, even null, SQL Server will allocate at least 2 additional pages to
start keeping track of that data.
FYI, for ANY fixed length data column, NULLs will take space. So a char(100)
that contains NULL will take the full 100 bytes.
