There is no way to loop through the columns in a table in a simple
fashion. This is because that it would rarely make any sense; columns
in a table are supposed to described distinct attribuets.

For a thing like this I would do:

SELECT 'UPDATE PROFILE SET ' + name + ' replace(substring( ' +
name + ', 1, 255), char(13) + char(10), '':'')'
FROM syscolumns
WHERE id = object_id('PROFILE')
and type_name(xtype) like '%char'

and the copy, paste and run result.
