LinkedIn Ads ODBC Driver

The LinkedIn Ads ODBC Driver is a powerful tool that allows you to connect with live data from LinkedIn Ads, directly from any applications that support ODBC connectivity.

Access LinkedIn Ads data like you would a database - read, write, and update LinkedIn Ads Analytics, Campaings, Conversion, Forms, etc. through a standard ODBC Driver interface.



Use the CData ODBC Driver for LinkedIn Ads and PolyBase to create an external data source in SQL Server 2019 with access to live LinkedIn Ads data.

PolyBase for SQL Server allows you to query external data by using the same Transact-SQL syntax used to query a database table. When paired with the CData ODBC Driver for LinkedIn Ads, you get access to your LinkedIn Ads data directly alongside your SQL Server data. This article walks through creating an external data source and external tables to grant access to live LinkedIn Ads data using T-SQL queries.

The CData ODBC drivers offer unmatched performance for interacting with live LinkedIn Ads data using PolyBase due to optimized data processing built into the driver. When you issue complex SQL queries from SQL Server to LinkedIn Ads, the driver pushes down supported SQL operations, like filters and aggregations, directly to LinkedIn Ads and utilizes the embedded SQL engine to process unsupported operations (often SQL functions and JOIN operations) client-side. And with PolyBase, you can also join SQL Server data with LinkedIn Ads data, using a single query to pull data from distributed sources.

Connect to LinkedIn Ads

If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs. To create an external data source in SQL Server using PolyBase, configure a System DSN (CData LinkedIn Ads Sys is created automatically).

LinkedIn Ads uses the OAuth authentication standard. OAuth requires the authenticating user to interact with LinkedIn using the browser. See the OAuth section in the Help documentation for a guide.

Click "Test Connection" to ensure that the DSN is connected to LinkedIn Ads properly. Navigate to the Tables tab to review the table definitions for LinkedIn Ads.

Create an External Data Source for LinkedIn Ads Data

After configuring the connection, you need to create a master encryption key and a credential database for the external data source.

Creating a Master Encryption Key

Execute the following SQL command to create a new master key, 'ENCRYPTION,' to encrypt the credentials for the external data source.

CREATE MASTER KEY ENCRYPTION BY PASSWORD = 'password';

Creating a Credential Database

Execute the following SQL command to create credentials for the external data source connected to LinkedIn Ads data.

NOTE: Since LinkedIn Ads does not require a User or Password to authenticate, you may use whatever values you wish for IDENTITY and SECRET.

CREATE DATABASE SCOPED CREDENTIAL linkedinads_creds
WITH IDENTITY = 'username', SECRET = 'password';

Create an External Data Source for LinkedIn Ads

Execute the following SQL command to create an external data source for LinkedIn Ads with PolyBase, using the DSN and credentials configured earlier.

For LinkedIn Ads, set SERVERNAME to 'localhost' or '127.0.0.1' and leave PORT empty. PUSHDOWN is set to ON by default, meaning the ODBC Driver can leverage server-side processing for complex queries.

CREATE EXTERNAL DATA SOURCE cdata_linkedinads_source
WITH ( 
  LOCATION = 'odbc://SERVERNAME[:PORT]',
  CONNECTION_OPTIONS = 'DSN=CData LinkedIn Ads Sys',
  -- PUSHDOWN = ON | OFF,
  CREDENTIAL = linkedinads_creds
);

Create External Tables for LinkedIn Ads

After creating the external data source, use CREATE EXTERNAL TABLE statements to link to LinkedIn Ads data from your SQL Server instance. The table column definitions must match those exposed by the CData ODBC Driver for LinkedIn Ads. You can refer to the Tables tab of the DSN Configuration Wizard to see the table definition.

Sample CREATE TABLE Statement

The statement to create an external table based on a LinkedIn Ads Analytics would look similar to the following:

CREATE EXTERNAL TABLE Analytics(
  VisibilityCode [nvarchar](255) NULL,
  Comment [nvarchar](255) NULL,
  ...
) WITH ( 
  LOCATION='Analytics',
  DATA_SOURCE=cdata_linkedinads_source
);

Having created external tables for LinkedIn Ads in your SQL Server instance, you are now able to query local and remote data simultaneously. Thanks to built-in query processing in the CData ODBC Driver, you know that as much query processing as possible is being pushed to LinkedIn Ads, freeing up local resources and computing power.
