How to usewith no test data, we started adding some test data to the products and suppliers in the database table first.Let's take a look at some simple usage examplesIn automatically generated ProductsController and SupplierscontrollerThe following action has been generated for usSo for some additions, modifications, deletions, updates, I don't do too many examples,These are not so mu

available.In this tutorial, you will learn how to expose Oracle database data using WCF data Services and OData through Oracle's Entity Framework support.First, create a new EDM from HR mode. Next, create a WCF data service that uses OData to expose the EDM through the Web. Finally, run the WEB application and execute a URL query to retrieve the data from the da

What is ODataOfficial explanation: The Open data Protocol (OData) is a data access Protocol for the web. OData provides a uniform to query and manipulate data sets through CRUD operations (create, read, update, and delete).Getting Started with ODataTo use OData, you have the following work to do. A. Install the

I. Overviewtime is ample, take some time to summarize the common usage of OData, Open Data Protocol (OData) is a Web protocol that queries and updates data. OData applies web technologies such as HTTP, Atom Publishing Protocol (ATOMPUB), and JSON to provide access to information for different applications, services, and storage. In addition to providing some basi

Queryable property Allowedorderbyproperties indicates that the default sort is followed by the ID field The Allowedqueryoptions property controls OData query conditions, such as So far, all the code has been written, and if anything is missing, I'll add it when I find it. Start the deployment below, deploy the environment for Windows Server R2, have installed 4.0 environment, here will be attention to the

The OData protocol, how cow B technology,Traditional page-writing habits, the recent project, using the ASP. NET WebAPI 2.0来 to do data interface, as for why to use WebAPI, I think as long as the OData protocol has a knowledge of friends. Just say that Webapi will think of this, if you want to have more in-depth understanding of it. You can take a brief introduction to the blog Park (Zhang Shanyu master). U

Odata-open Data Protocol 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 standard. But in some scenarios, there is a standard that can bring g

(When installing "Mysql-connector-net-6.6.7.msi", if your development machine installed MySQL software, there may be some problems, usually in "programs and features" in the original deleted, Install the new, or you will choose the data source, there is no "Mysql database" this option) A "*.edmx" file appears in the project, which is the file created by EF At this point, create a new controller file, y

possibility of data interaction across the network (through DCOM), the implementation of the OLE DB Standard is a set of C + + API functions, like the ODBC API in ODBC standards, and, unlike, OLE DB API is COM compliant, object-based (the ODBC API is a simple C API). Using the OLE DB APIs, you can write applications that have access to any data source that conforms to OLE DB standards, or you can write query handlers for a particular data store (

the target: 1, easy to use. 2, easy to change. 3, easy to replace. Webapi just said, OData, indeed very powerful also very flexible, just too flexible, resulting in increased learning costs and time, then can also be encapsulated, become familiar with the way? train of Thought Someone may see this picture and think back: I k, need to be so complicated? Over-design it. In fact, this view of personal experience, experienced is very easy to un

Understanding of a front-end AngularJS, back-end OData, ASP. NET Web API case, angularjsodata Still chsakell, he wrote a front-end AngularJS, back-end OData, ASP.

odatacompositekeysampleproject. Here we see another difference between WebApi OData and WCF Data Services. In WCF Data Services, the framework handles generating a query, which selects a single instance from an IQueryable . This limits we ability to customize how finding a instance by key was done. In WebApi OData, we had to explicitly define a overload that get

Use the OData Singleton mode in ASP. NET Web APIs, apiodata We have added support for Singleton Mode Since OData v4. We don't need to obtain an EDM every time based on the primary key, just like using Singleton mode in C. The implementation method generally takes two steps: 1. Add the [Singleton] feature to the navigation attribute for implementing the Singleton mode.2. Use builder. Singleton Start with
