It would be great if at least union aggregate could be supported for SQL08 using the XML PATH hack. I'm using SQL Azure and I'm at Microsoft's whim for when they decide to upgrade us.

The following aggregates will be supported by SQL Server Code-Named "Denali" as static methods on geography and geometry types:

  • UnionAggregate

  • EnvelopeAggregate

  • CollectionAggregate

  • ConvexHullAggregate
