odata query

When you use oddata to obtain CRM data, the default query result contains only 50 records. You can use the "_ next" attribute in the object returned by JSON as a URL loop until the property is empty. The sample code is as follows: relatedAccounts = [];function onload() { var serverUrl = Xrm.Page.context.getServerUrl(); var oDataUri = serverUrl + "/xrmservices/2011/OrganizationData.svc/AccountSet?$select=AccountId,Name,$filter=StateCode/Value e

This is my personal 拙笔 when I use ASP. NET MVC WebAPI to support the OData protocol for paging query services.The code has been developed on the Oschina. Interested friends can see, welcome to point out the shortcomings.I've seen a few articles in the garden about ASP. NET MVC WebAPI Support OData protocol, very inspired,But for the data paged

and the possibility of cross-Network Data Interaction (through DCOM ), the specific implementation of the ole db standard is a set of C ++ API functions, just like the odbc api in the ODBC standard, the difference is that, ole db APIs comply with COM standards and are object-based (ODBC APIs are simple C APIs ). Using the ole db api, you can write applications that can access any data source that meets the ole db standard, or query processor for a sp

overridable methods to update and query entities, so you'll find that you can rewrite a lot of ways such as: Get (), Getentitybykey (), Createentrty (), Patchentity (), updateentity (), etc ...As I mentioned earlier, we will create a read-only controller, which means that we only implement the read operation, explaining the implementation of the above code:1. Rewrite the Get () method and attach the [queryable] attribute, which means we allow the cli

ObjectiveLong time no update, before there are many things, so dragged for a long time, very sorry. Well, don't say much nonsense, let's start with the subject. This article still uses the previous season's project background (series address http://www.cnblogs.com/fzrain/p/3490137.html) to demonstrate the OData service, so we can directly use the previously built data access layer. But not to be sure to see everything before, we just borrowed the data

Season 1 link and series navigation: http://www.cnblogs.com/fzrain/p/3490137.html Here, I would like to thank Taiseer Joudeh for bringing us the latest technology sharing. The landlord liked web api technology and received support from many friends, therefore, it is inevitable to continue. After the previous phase of study, we should be no stranger to web APIs. From this article, we will start to introduce OData. I have just started learning, so I wi

What is What–odata?Odata-open Data Protocal is a standard for designing and using restful APIs. Rest itself is just a thought and idea for building Web services, and it does not provide a unified standard to limit how developers can design restful APIs. In fact, our actual development did not follow a unified standard to design WEBAPI. Because in most scenarios, it is not necessary to follow a unified stand

Http://www.cnblogs.com/shanyou/archive/2013/06/11/3131583.htmlIn the SOA world, one of the most important concepts is the contract (contract). In the world of cloud computing, the most important concept of communication is the contract. XML has a strong ability to describe data, both atom format and atompub are built on XML, and have been standard driven by Google and Microsoft. However, compared with real data interaction protocols such as atom/atompub and Odbc/oledb, there is a fundamental def

conventions are defined above the standard to support the exchange of query and schema information.

using Action or Function is that we can transfer the query responsibility to the server, especially in complex queries, which can reduce unnecessary troubles on the client. The actions and functions of OData are a little different. They are defined in the specification as "a group of extensions that can be executed, can be used as services, or can be used as resources ". The main difference is that Funct

Windows Authentication and odata 1. Server Side 1) Integrated Authentication When IIS is used as the service host, you must enable integrated authentication to disable anonymous authentication. Windows authentication requests contain the following HTTP headers) WWW-Authenticate: NTLMWWW-Authenticate: negotiate NTLM means that you need to use Windows authentication. Negotiate means that the client can try Kerberos authentication. 2)

ASP. NET Web API 2.2 for OData v4.0 daily build version is now released. The Team also released OData core library version 6.1 on nuget, which contains several Bug fixes and new features, especially added support for OData v4 specifications. However, Microsoft's team said that WCF would not obtain the unique features of OData
