The segment of a query that indicates whether data should be returned inline instead of as deferred content.
Assembly: System.Data.Services (in System.Data.Services.dll)
An $expandclause indicates that each $expanditem should be fully expanded. For example, the value OrderLines.Product.Image with $expand causes OrderLines, the Product of each element in OrderLines, and the Image of the Product of each element in OrderLines to be expanded.
The left-most property in an $expand clause must be a property on the entity type within the entity set identified by the last path segment in the request URI.
Redundant expand clause rules are acceptable and ignored.
The following URI expands the OrderLines associated with each Order returned by the query.
Windows 7, Windows Vista, Windows XP SP2, Windows Server 2008 R2, Windows Server 2008, Windows Server 2003
