2.2.3.67.2 Fetch (Sync)

The Fetch element is an optional child element of the Commands element in Sync command requests and an optional child element of the Responses element in Sync command responses. In a request, the Fetch element is used to request the application data of an item that was truncated in a synchronization response from the server. The complete item is then returned to the client in a server response.

The ItemOperations command (section 2.2.1.10) is the preferred way to fetch items.

All elements referenced in this section are defined in the AirSync namespace.

Command request/response	Parent elements	Child elements	Data type	Number allowed
Sync command request (section 2.2.1.21)	Commands (section 2.2.3.32)	ServerId (section 2.2.3.166.8)	container ([MS-ASDTYPE] section 2.2)	0...N (optional)
Sync command response	Responses (section 2.2.3.154)	ServerId Status (section 2.2.3.177.17) ApplicationData (section 2.2.3.11)	container	0...N (optional)

The Fetch element cannot be used to get truncated calendar, contact, note, recipient information, or task items from the server.

The server is not required to send an individual response for every operation that is sent by the client. The client only receives responses for successful additions, successful fetches, successful changes that include an attachment being added, and failed changes and deletions. When the client does not receive a response, the client MUST assume that the operation succeeded unless informed otherwise.
