Hi, does anybody knows if it is possible to query the umbraco database with a select? I have a custom document type named "Product" and i'd like to query the db in order to select only products with colour=red or with quantity > 100. Is it possible? I don't use xslt just razor macro or user control macro with umbraco 4.11. So far I accomplish that by using uQuery.GetDocument(9999).GetChildDocuments() and then filter the list with a foreach but that loads all product in-memory.
Sure this is possible as lang as you know the database and table architecture. But I wouln't recommend this. A better way would be a LINQ query, but I don't know how those are mapped in behind against the database. Does anyone ones more about the LINQ possibilities against the umbraco backend?
@Andreas - since the published nodes are using the XML cache, they are fast. Documents on the other hand, can follow the same LINQ syntax, but they will hit the database a good few times! :-(

Hi Gian,
Assuming that your content is published, you could use `uQuery.GetNodesByXPath`?
var nodes = uQuery.GetNodesByXPath("//*[@isDoc and colour = 'red']");Then once you have the nodes, you can get the Document from the Id.
Cheers, Lee.
If XPath isn't your thing... you could use LINQ syntax:
var nodes = uQuery.GetRootNode().GetDescendantNodes(x => x.GetProperty<string>("colour") == "red");Cheers, Lee.
Thanks lee for pointing the LINQ way out.

Lee, as fast as ever !
FYI, the XPath way would be more efficient, as only the nodes in the result set will be constructed (+ it gets compiled and cached).
I've decided for and xpath solution since there will be a lot of products . Thank you all very much!

Hi Gian, great, happy to help.
(Don't forgot to mark the post as a solution)
Thanks, Lee.
