LINQ to SuiteCRM Data


LINQ offers versatile querying capabilities within the .NET Framework (v3.0+), offering a straightforward method for programmatic data access through CData ADO.NET Data Providers. In this article, we demonstrate the use of LINQ to retrieve information from the SuiteCRM Data Provider.

This article illustrates using LINQ to access tables within the SuiteCRM via the CData ADO.NET Data Provider for SuiteCRM. To achieve this, we will use LINQ to Entity Framework, which facilitates the generation of connections and can be seamlessly employed with any CData ADO.NET Data Providers to access data through LINQ.

See the help documentation for a guide to setting up an EF 6 project to use the provider.

  1. In a new project in Visual Studio, right-click on the project and choose to add a new item. Add an ADO.NET Entity Data Model.
  2. Choose EF Designer from Database and click Next.
  3. Add a new Data Connection, and change your data source type to "CData SuiteCRM Data Source".

  4. Enter your data source connection information.

    The User and Password properties must be set to valid SuiteCRM user credentials. Additionally, specify the URL to the SuiteCRM application, for example http://suite.crm.com.

    Note that retrieving SuiteCRM metadata can be expensive. It is advised that you store the metadata locally as described in the Caching Metadata section of the data provider help documentation.

    Below is a typical connection string:

    URL=http://mySuiteCRM.com;User=myUser;Password=myPassword;
  5. If saving your entity connection to App.Config, set an entity name. In this example we are setting SuiteCRMEntities as our entity connection in App.Config.
  6. Enter a model name and select any tables or views you would like to include in the model.

Using the entity you created, you can now perform select , update, delete, and insert commands. For example:

SuiteCRMEntities context = new SuiteCRMEntities(); var accountsQuery = from accounts in context.Accounts select accounts; foreach (var result in accountsQuery) { Console.WriteLine("{0} {1} ", result.Id, result.Name); }

See "LINQ and Entity Framework" chapter in the help documentation for example queries of the supported LINQ.
