Looks likely you could do this with some dynamic SQL:

DECLARE @datestr char(13),
@sql nvarchar(MAX)
SELECT @datestr = convert(char(8), getdate(), 112) + '_' +
convert(char(5), getdate(), 108)
SELECT @datestr = replace (@datestr, ':', '')
SELECT @sql =
'create database Snapshotter_snap_ ' + @datestr + ' on
' ( name = Snapshotter, filename =
''c:\temp\Snapshotter_snap_' + @datestr + '.ss'')
as snapshot of Snapshotter'
EXEC(@sql)
