OData Connector for Talend Studio OData Connector can be used to integrated any REST API which supports OData Standard. You can view tables, read data from tables using this connector. It also comes with some example OData Services to get started. In this article you will learn how to quickly and efficiently integrate OData data in Talend Studio without coding. We will use high-performance OData Connector to easily connect to OData and then access the data inside Talend Studio. Let's follow the steps below to see how we can accomplish that! Download Documentation OData Connector for Talend Studio is based on ZappySys API Driver which is part of ODBC PowerPack. It is a collection of high-performance ODBC drivers that enable you to integrate data in SQL Server, SSIS, a programming language, or any other ODBC-compatible application. ODBC PowerPack supports various file formats, sources and destinations, including REST/SOAP API, SFTP/FTP, storage services, and plain files, to mention a few.

Create Data Source in ZappySys Data Gateway based on API Driver

1. Download and install ODBC PowerPack.

2. Search for gateway in start menu and Open ZappySys Data Gateway:
   

3. Go to Users Tab to add our first Gateway user. Click Add; we will give it a name tdsuser and enter password you like to give. Check Admin option and click OK to save. We will use these details later when we create linked server:
   

4. Now we are ready to add a data source. Click Add, give data source a name (Copy this name somewhere, we will need it later) and then select Native - ZappySys API Driver. Finally, click OK. And it will create the Data Set for it and open the ZS driver UI.

   OdataDSN

   
   

5. When the Configuration window appears give your data source a name if you haven't done that already, then select "OData" from the list of Popular Connectors. If "OData" is not present in the list, then click "Search Online" and download it. Then set the path to the location where you downloaded it. Finally, click Continue >> to proceed with configuring the DSN:

7. Once the data source connection has been configured, it's time to configure the SQL query. Select the Preview tab and then click Query Builder button to configure the SQL query:

   

   ZappySys API Driver - OData

   OData Connector can be used to integrated any REST API which supports OData Standard. You can view tables, read data from tables using this connector. It also comes with some example OData Services to get started.

   OdataDSN

   

8. Start by selecting the Table or Endpoint you are interested in and then configure the parameters. This will generate a query that we will use in Talend Studio to retrieve data from OData. Hit OK button to use this query in the next step.

   SELECT * FROM Customers

   
   Some parameters configured in this window will be passed to the OData API, e.g. filtering parameters. It means that filtering will be done on the server side (instead of the client side), enabling you to get only the meaningful data much faster.

9. Now hit Preview Data button to preview the data using the generated SQL query. If you are satisfied with the result, use this query in Talend Studio:

   OdataDSN

   SELECT * FROM Customers

   
   You can also access data quickly from the tables dropdown by selecting <Select table>.
   A WHERE clause, LIMIT keyword will be performed on the client side, meaning that the whole result set will be retrieved from the OData API first, and only then the filtering will be applied to the data. If possible, it is recommended to use parameters in Query Builder to filter the data on the server side (in OData servers).

10. Click OK to finish creating the data source.

Read OData data in Talend Studio

To read OData data in Talend Studio, we'll need to complete several steps. Let's get through them all right away!

Create connection for input

1. First of all, open Talend Studio
2. Create a new connection:
3. Select Microsoft SQL Server connection:
4. Name your connection:
5. Fill-in connection parameters and then click Test connection:
   OdataDSN

   
6. If the List of modules not installed for this operation window shows up, then download and install all of them:
   Review and accept all additional module license agreements during the process
7. Finally, you should see a successful connection test result at the end:

Add input

1. Once we have a connection to ZappySys Data Gateway created, we can proceed by creating a job:
2. Simply drag and drop ZappySys Data Gateway connection onto the job:
3. Then create an input based on ZappySys Data Gateway connection:
4. Continue by configuring a SQL query and click Guess schema button:
5. Finish by configuring the schema, for example:

Add output

Run the job

Conclusion

In this article we showed you how to connect to OData in Talend Studio and integrate data without any coding, saving you time and effort. It's worth noting that ZappySys API Driver allows you to connect not only to OData, but to any Java application that supports JDBC (just use a different JDBC driver and configure it appropriately).

We encourage you to download OData Connector for Talend Studio and see how easy it is to use it for yourself or your team.
