The following members accept/return AggregateOperand objects:
The AggregateOperand is used to compose criteria which are based on the collection properties (the "many" end of a one-to-many or many-to-many relationship) to filter the XPCollection. It represents the results of aggregate operations performed on these types of properties.
AggregateOperand does not support nested expressions and complex property paths like
Max(Document.<PersonID>LastName). Only names of owned properties are supported:
- AggregateOperand may produce null instead of zero for an empty collection on a server side.
