Totally different capabilities.
A sequence is not tied to a table: It is an independent object.
One can use a sequence to number count by any increment positive or
negative, assign the values to one table or to multiple tables, and
to repeatedly cycle through a fixed set of numbers (min to max and
back to min), and much more.
Maybe in SQL Server 2009?
