Client Object Model Equivalent of SPSiteDataQuery?

Question

I'm looking for an equivalent to the SPSiteDataQuery functionality in the Client Object Model (COM).

The CamlQuery can be used with an instance of List to execute SPQuery level of aggregation, but is there an equivalent to site collection level queries for the COM?

Checked the Web object: http://msdn.microsoft.com/en-us/library/microsoft.sharepoint.client.web_members.aspx and also the Site object http://msdn.microsoft.com/en-us/library/microsoft.sharepoint.client.site.aspx and don't see anything there. SubwebQuery http://msdn.microsoft.com/en-us/library/microsoft.sharepoint.client.subwebquery.aspx had a promising name, but turns out that it's not what I'm looking for.

Perhaps there's no equivalent functionality in the COM?

Any pointers would be appreciated.

Answer 1

There is no equivalent.

Per MSDN (suggested alternative at the end):

The CSOM does not provide a mechanism for querying data across multiple lists that are not associated by a lookup field. In other words, there is no client-side functional equivalent of the SPSiteDataQuery class. If you need to perform a cross-list query from client-side code, consider creating a list view on the server that performs the list aggregation. You can then query the aggregated data from your client-side code.from your client-side code.
