Connect to Live Anaplan Data in PostGresSQL Interface through CData Connect AI

There are a vast number of PostgreSQL clients available on the Internet. PostgreSQL is a popular interface for data access. When you pair PostgreSQL with CData Connect AI, you gain database-like access to live Anaplan data from PostgreSQL. In this article, we walk through the process of connecting to Anaplan data in Connect AI and establishing a connection between Connect AI and PostgreSQL using a TDS foreign data wrapper (FDW).

CData Connect AI provides a pure SQL Server interface for Anaplan, allowing you to query data from Anaplan without replicating the data to a natively supported database. Using optimized data processing out of the box, CData Connect AI pushes all supported SQL operations (filters, JOINs, etc.) directly to Anaplan, leveraging server-side processing to return the requested Anaplan data quickly.

Connect to Anaplan in Connect AI

CData Connect AI uses a straightforward, point-and-click interface to connect to data sources.

1. Log into Connect AI, click Sources, and then click Add Connection

2. Select "Anaplan" from the Add Connection panel

3. Enter the necessary authentication properties to connect to Anaplan.

   Authenticating to Anaplan

   The driver supports authenticating with Basic, Certificate, or OAuth. In every case, set Region to the region where your Anaplan account data is hosted (e.g., US1, which is the default).

   Using Basic Authentication

   Set AuthScheme to Basic, then supply your Anaplan User and Password. If your workspace uses single sign-on (SSO), you must be assigned as an Exception User to use Basic authentication.

   Using Certificate Authentication

   Set AuthScheme to Certificate, then supply the Certificate, CertificateType, and PrivateKey properties (and the matching CertificatePassword / PrivateKeyPassword if either is encrypted). The certificate must be a CA-issued X.509 certificate registered with your Anaplan tenant administrator.

   Using OAuth Authentication

   Register a custom OAuth application in Anaplan, then set the following properties:

   • OAuthClientId: The client Id assigned when you registered your custom OAuth application.
   • OAuthClientSecret: The client secret assigned when you registered your custom OAuth application.
   • CallbackURL: The redirect URI defined when you registered your application.
   • InitiateOAuth: Set to GETANDREFRESH to have the driver manage the OAuth token exchange and refresh automatically.

   See the Getting Started chapter of the help documentation for a guide to creating a custom OAuth app and using OAuth.

   
4. Click Save & Test
5. Navigate to the Permissions tab in the Add Anaplan Connection page and update the User-based permissions.

Add a Personal Access Token

When connecting to Connect AI through the REST API, the OData API, or the Virtual SQL Server, a Personal Access Token (PAT) is used to authenticate the connection to Connect AI. It is best practice to create a separate PAT for each service to maintain granularity of access.

1. Click on the Gear icon () at the top right of the Connect AI app to open the settings page.
2. On the Settings page, go to the Access Tokens section and click Create PAT.
3. Give the PAT a name and click Create.
4. The personal access token is only visible at creation, so be sure to copy it and store it securely for future use.

With the connection configured and a PAT generated, you are ready to connect to Anaplan data from PostgreSQL.

Build the TDS Foreign Data Wrapper

The Foreign Data Wrapper can be installed as an extension to PostgreSQL, without recompiling PostgreSQL. The tds_fdw extension is used as an example (https://github.com/tds-fdw/tds_fdw).

1. You can clone and build the git repository via something like the following view source:

   
   sudo apt-get install git
   git clone https://github.com/tds-fdw/tds_fdw.git
   cd tds_fdw
   make USE_PGXS=1
   sudo make USE_PGXS=1 install
   

   Note: If you have several PostgreSQL versions and you do not want to build for the default one, first locate where the binary for pg_config is, take note of the full path, and then append PG_CONFIG= after USE_PGXS=1 at the make commands.
2. After you finish the installation, then start the server:

   
   sudo service postgresql start
   

3. Then go inside the Postgres database

   
   psql -h localhost -U postgres -d postgres
   

   Note: Instead of localhost you can put the IP where your PostgreSQL is hosted.

Connect to Anaplan data as a PostgreSQL Database and query the data!

After you have installed the extension, follow the steps below to start executing queries to Anaplan data:

1. Log into your database.
2. Load the extension for the database:

   
   CREATE EXTENSION tds_fdw;
   

3. Create a server object for Anaplan data:

   
   CREATE SERVER "Anaplan1" FOREIGN DATA WRAPPER tds_fdw OPTIONS (servername'tds.cdata.com', port '14333', database 'Anaplan1');
   

4. Configure user mapping with your email and Personal Access Token from your Connect AI account:

   
   CREATE USER MAPPING for postgres SERVER "Anaplan1" OPTIONS (username '[email protected]', password 'your_personal_access_token' );
   

5. Create the local schema:

   
   CREATE SCHEMA "Anaplan1";
   

6. Create a foreign table in your local database:

   
   #Using a table_name definition:
   
   CREATE FOREIGN TABLE "Anaplan1".Sales  (      
   id varchar,      
   Product varchar)      
   SERVER "Anaplan1"
   OPTIONS(table_name 'Anaplan.Sales', row_estimate_method 'showplan_all');
   
   #Or using a schema_name and table_name definition:
   
   CREATE FOREIGN TABLE "Anaplan1".Sales (      
   id varchar,      
   Product varchar)      
   SERVER "Anaplan1"
   OPTIONS (schema_name 'Anaplan', table_name 'Sales', row_estimate_method 'showplan_all');
   
   #Or using a query definition:
   
   CREATE FOREIGN TABLE  "Anaplan1".Sales (
   id varchar,      
   Product varchar)      
   SERVER "Anaplan1"
   OPTIONS (query 'SELECT * FROM Anaplan.Sales', row_estimate_method 'showplan_all');
   
   #Or setting a remote column name:
   
   CREATE FOREIGN TABLE "Anaplan1".Sales (
   id varchar,
   col2 varchar OPTIONS (column_name 'Product'))
   SERVER "Anaplan1"
   OPTIONS (schema_name 'Anaplan', table_name 'Sales', row_estimate_method 'showplan_all');
   

7. You can now execute read/write commands to Anaplan:

   
   SELECT id, Product
   FROM "Anaplan1".Sales;
