I am playing with Raven DB for few days and I would like to use it as a storage for my Web chat application. I have document which contains some user data and chat history - which is big collection chat messages. Each time I load user document chat history is also loaded, even if I need only few fields like: user name, password and email. My question is: how to load only part of document from database ? Tomek, You can't load a partial document, but you can load a projection. session.Query<User>() .Where(x=>x.Name == name) .Select( x=> new { x.Name, x.Email }); That will load only the

I'm using RavenDB build 371 and I have the following model: class Product { public string Id { get; set; } public ProductSpec[] Specs { get; set; } } class ProductSpec { public string Name { get; set; } public string Value { get; set; } } I would like to be able to query for products which have a set of specs. When querying by a single spec: session.Query<Product>() .Where(product => product.Specs.Any(spec => spec.Name == "Color" && spec.Value == "Red")) .ToList(); The expected results are returned, however when an additional spec predicate is added: session.Query<Product>() .Where(product =>

My entity is: class Resource { string Name; string EmployeeId; } How do I query for resources of multiple employees? I tried this: Resource[] FindResourcesByEmployees(string[] employeeIds) { return this.Session.Query<Resource>() .Where(r => employeeIds.Contains(r.EmployeeId)) .ToArray(); } However that gives me NotSupportedException: Method not supported: Contains. Then I tried the following method: Resource[] FindResourcesByEmployees(string[] employeeIds) { return this.Session.Query<Resource>() .Where(r => employeeIds.Any(v => v == r.EmployeeId)) .ToArray(); } That throws

I'm looking for an example of how to implement and use Map-Reduce within the RavenDB .NET Client. I'd like to apply it to a specific scenario: generating unique and total visitor counts. A sample document that would be stored within RavenDB: public class StatisticsEntry { public string Id { get; set; } public string UserId { get; set; } } I can figure out how to create a standard index using Map, but I'm lost as to how to actually use the Reduce function, and then retrieve the results. Unfortunately, the example provided on the RavenDB Site doesn't explain what's going on so that I can

I'm trying to build a RavenApiController with the new ASP.NET 5.0 (aka Asp.Net vNext) stuff and can't seem to get the RavenDB.Client references to work at all. The error I get is Error CS0246 The type or namespace name 'Raven' could not be found (are you missing a using directive or an assembly reference?) SharedIO.ASP.NET Core 5.0 RavenApiController.cs 3 My project.json is as follows { "webroot": "wwwroot", "version": "1.0.0-*", "exclude": [ "wwwroot" ], "packExclude": [ "**.kproj", "**.user", "**.vspscc" ], "dependencies": { "Microsoft.AspNet.Server.IIS": "1.0.0-beta2", "Microsoft.AspNet

How do I disable RavenDB replication? The reason for that is I have a simple database on one server and I don't need any replication at this point. IDocumentStore tmpStore = new DocumentStore { Url = url }; tmpStore.Initialize(); tmpStore.DatabaseCommands.EnsureDatabaseExists(dbName); // WebException If I try to ensure that database was created I get a WebException with HTTP status 404. This error occurred when RavenDB makes request to /docs/Raven/Replication/Destinations . Or shall I just ignore this exception? The web exception is thrown and caught internally inside RavenDB Client. You can
