Execute LINQ queries to Sage 300 data in LINQPad.
The CData ADO.NET Provider for Sage 300 enables you to use standard ADO.NET interfaces like LINQ and the Entity Framework to work with Sage 300 data. This article will demonstrate the process of establishing a connection from LINQPad and executing LINQ queries.
Create the Data Model
After downloading and installing both the provider and LINQPad, create a new class library project within Visual Studio.
See the help documentation for a guide to setting up an EF 6 project to use the provider.
Right-click your project and click Add -> New Item -> ADO.NET Entity Data Model. In the resulting dialog, select Code First from database. Click New Connection and specify the connection string options in the resulting wizard.
Sage 300 requires some initial setup in order to communicate over the Sage 300 Web API.
- Set up the security groups for the Sage 300 user. Give the Sage 300 user access to the
option under Security Groups (per each module required). - Edit both web.config files in the /Online/Web and /Online/WebApi folders; change the key AllowWebApiAccessForAdmin to true. Restart the webAPI app-pool for the settings to take.
- Once the user access is configured, click https://server/Sage300WebApi/ to ensure access to the web API.
Authenticate to Sage 300 using Basic authentication.
Connect Using Basic Authentication
You must provide values for the following properties to successfully authenticate to Sage 300. Note that the provider reuses the session opened by Sage 300 using cookies. This means that your credentials are used only on the first request to open the session. After that, cookies returned from Sage 300 are used for authentication.
- Url: Set this to the url of the server hosting Sage 300. Construct a URL for the Sage 300 Web API as follows: {protocol}://{host-application-path}/v{version}/{tenant}/ For example, http://localhost/Sage300WebApi/v1.0/-/.
- User: Set this to the username of your account.
- Password: Set this to the password of your account.
Below is a typical connection string:
User=SAMPLE;Password=password;URL=http://127.0.0.1/Sage300WebApi/v1/-/;Company=SAMINC;
- Set up the security groups for the Sage 300 user. Give the Sage 300 user access to the
Select the desired tables and views and click Finish to create the data model.
- Build the project. The generated files can be used to create the Sage 300 connection in LINQPad.
Connect to Sage 300 Data in LINQPad
After you have obtained the required connection properties and created the data model assembly, follow the steps below to start using the data model in LINQPad.
Open LINQPad and click Add Connection.
Select the "Use a typed data context from your own assembly" option.
Select Entity Framework DbContext.
Click Browse next to the Path to Custom Assembly box and browse to your project folder. Browse to the .dll or .exe under the bin folder.
- Select the name of the DbContext.
- If you saved your connection string in App.Config, specify the path to the App.config.
You can now query Sage 300 data through LINQPad. For examples of the supported LINQ queries, see the "LINQ and Entity Framework" chapter in the help documentation.
