How to connect PolyBase to ActiveCampaign

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 ActiveCampaign, you get access to your ActiveCampaign data directly alongside your SQL Server data. This article describes creating an external data source and external tables to grant access to live ActiveCampaign data using T-SQL queries.

NOTE: PolyBase is only available on SQL Server 19 and above, and only for Standard SQL Server.

The CData ODBC drivers offer unmatched performance for interacting with live ActiveCampaign data using PolyBase due to optimized data processing built into the driver. When you issue complex SQL queries from SQL Server to ActiveCampaign, the driver pushes down supported SQL operations, like filters and aggregations, directly to ActiveCampaign 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 ActiveCampaign data, using a single query to pull data from distributed sources.

Connect to ActiveCampaign

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 ActiveCampaign Sys is created automatically).

ActiveCampaign supports authenticating with the API Key. To connect to ActiveCampaign, set the following:

• URL: This can be found in your account on the My Settings page under the Developer tab. For example: https://{yourAccountName}.api-us1.com
• APIKey: This can be found in your account on the Settings page under the Developer tab. Each user in your ActiveCampaign account has their own unique API key.

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

Create an External Data Source for ActiveCampaign 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 ActiveCampaign data.

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

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

Create an External Data Source for ActiveCampaign

Execute a CREATE EXTERNAL DATA SOURCE SQL command to create an external data source for ActiveCampaign with PolyBase:

• Set the LOCATION parameter , using the DSN and credentials configured earlier.

For ActiveCampaign, set SERVERNAME to the URL or address for your server (e.g. 'localhost' or '127.0.0.1' for local servers; the remote URL for remote servers). 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_activecampaign_source
WITH ( 
  LOCATION = 'odbc://SERVER_URL',
  CONNECTION_OPTIONS = 'DSN=CData ActiveCampaign Sys',
  -- PUSHDOWN = ON | OFF,
  CREDENTIAL = activecampaign_creds
);

Create External Tables for ActiveCampaign

After creating the external data source, use CREATE EXTERNAL TABLE statements to link to ActiveCampaign data from your SQL Server instance. The table column definitions must match those exposed by the CData ODBC Driver for ActiveCampaign. 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 ActiveCampaign Contacts would look similar to the following:

CREATE EXTERNAL TABLE Contacts(
  LastName [nvarchar](255) NULL,
  Email [nvarchar](255) NULL,
  ...
) WITH ( 
  LOCATION='Contacts',
  DATA_SOURCE=cdata_activecampaign_source
);

Having created external tables for ActiveCampaign 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 ActiveCampaign, freeing up local resources and computing power.
