How do i enable SPARSE on all the valid columns in an existing table ?

- is your db-level 100 ?
- I should be possible to alter your column defs, but you must check the restrictions on sparse columns: http://msdn.microsoft.com/en-us/library/cc280604.aspx
BOL also states sparse as an attribute of the alter table - alter column statement. http://msdn.microsoft.com/en-us/library/ms190273.aspx so that may be the way to go.
