OData Connector for Azure Data Factory (Pipeline)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 Azure Data Factory (Pipeline) without coding. We will use high-performance OData Connector to easily connect to OData and then access the data inside Azure Data Factory (Pipeline). Let's follow the steps below to see how we can accomplish that! OData Connector for Azure Data Factory (Pipeline) 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 ODBC Data Source (DSN) based on ZappySys API Driver
Step-by-step instructions
To get data from OData using Azure Data Factory (Pipeline) we first need to create a DSN (Data Source) which will access data from OData. We will later be able to read data using Azure Data Factory (Pipeline). Perform these steps:
-
Download and install ODBC PowerPack.
-
Open ODBC Data Sources (x64):
-
Create a User data source (User DSN) based on ZappySys API Driver
ZappySys API Driver-
Create and use User DSN
if the client application is run under a User Account.
This is an ideal option
in design-time , when developing a solution, e.g. in Visual Studio 2019. Use it for both type of applications - 64-bit and 32-bit. -
Create and use System DSN
if the client application is launched under a System Account, e.g. as a Windows Service.
Usually, this is an ideal option to use
in a production environment . Use ODBC Data Source Administrator (32-bit), instead of 64-bit version, if Windows Service is a 32-bit application.
Azure Data Factory (Pipeline) uses a Service Account, when a solution is deployed to production environment, therefore for production environment you have to create and use a System DSN. -
Create and use User DSN
if the client application is run under a User Account.
This is an ideal option
-
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:
OdataDSNOData -
Now it's time to configure the Connection Manager. Select Authentication Type, e.g. Token Authentication. Then select API Base URL (in most cases, the default one is the right one). More info is available in the Authentication section.
Fill in all required parameters and set optional parameters if needed:

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 - ODataOData 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 -
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 Azure Data Factory (Pipeline) 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 datamuch faster . -
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 Azure Data Factory (Pipeline):

You can also access data quickly from the tables dropdown by selecting <Select table>.AWHERE
clause,LIMIT
keyword will be performed on the client side, meaning that thewhole 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). -
Click OK to finish creating the data source.

-
Select "Azure, Self-Hosted" option:
-
Select "Self-Hosted" option:
-
Set a name, we will use "OnPremisesRuntime":
-
Download and install Microsoft Integration Runtime.
-
Launch Integration Runtime and copy/paste Authentication Key from Integration Runtime configuration in Azure Portal:
-
After finishing registering the Integration Runtime node, you should see a similar view:
-
Go back to Azure Portal and finish adding new Integration Runtime. You should see it was successfully added:
-
Go to Linked services section and create a new Linked service based on ODBC:
-
Select "ODBC" service:
-
Configure new ODBC service. Use the same DSN name we used in the previous step and copy it to Connection string box:
OdataDSNDSN=OdataDSN -
For created ODBC service create ODBC-based dataset:
-
Go to your pipeline and add Copy data connector into the flow. In Source section use OdbcDataset we created as a source dataset:
-
Then go to Sink section and select a destination/sink dataset. In this example we use precreated AzureBlobStorageDataset which saves data into an Azure Blob:
-
Finally, run the pipeline and see data being transferred from OdbcDataset to your destination dataset:
