RE: XQuery Update to return values

Hi Martin,

What is the syntax that X-Hive/DB supports for returning values? Or are
there any documents I can have a look at? Thanks.

When I implemented the XQuery update spec for X-Hive/DB I deliberately
chose not to follow that path, but rather to allow update expressions to
return values. I still can't see any need or technical merit in that
limitation, and it really hurts if you want to do something as simple as
returning how many items were changed. I think there should still be an
open bug in W3C's bugzilla about that issue.
