Build a PostgreSQL Interface for Salesforce Marketing Data using the CData JDBC Driver

There are a vast number of PostgreSQL clients available on the Internet. From standard Drivers to BI and Analytics tools, PostgreSQL is a popular interface for data access. Using our JDBC Drivers, you can now create PostgreSQL entry-points that you can connect to from any standard client.

To access Salesforce Marketing data as a PostgreSQL database, use the CData JDBC Driver for Salesforce Marketing and a JDBC foreign data wrapper (FDW). In this article, we compile the FDW, install it, and query Salesforce Marketing data from PostgreSQL Server.

Connect to Salesforce Marketing Data as a JDBC Data Source

To connect to Salesforce Marketing as a JDBC data source, you will need the following:

• Driver JAR path: The JAR is located in the lib subfolder of the installation directory.

• Driver class:

  cdata.jdbc.sfmarketingcloud.SFMarketingCloudDriver
  

• JDBC URL: The URL must start with "jdbc:sfmarketingcloud:" and can include any of the connection properties in name-value pairs separated with semicolons.

  Authenticating to the Salesforce Marketing Cloud APIs

  Set the User and Password to your login credentials, or to the credentials for a sandbox user if you are connecting to a sandbox account.

  Connecting to the Salesforce Marketing Cloud APIs

  By default, the data provider connects to production environments. Set UseSandbox to true to use a Salesforce Marketing Cloud sandbox account.

  The default Instance is s7 of the Web Services API; however, if you use a different instance, you can set Instance.

  Built-in Connection String Designer

  For assistance in constructing the JDBC URL, use the connection string designer built into the Salesforce Marketing JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

  java -jar cdata.jdbc.sfmarketingcloud.jar
  

  Fill in the connection properties and copy the connection string to the clipboard.

  

  A typical JDBC URL is below:

  jdbc:sfmarketingcloud:User=myUser;Password=myPassword;InitiateOAuth=GETANDREFRESH
  

Build the JDBC Foreign Data Wrapper

The Foreign Data Wrapper can be installed as an extension to PostgreSQL, without recompiling PostgreSQL. The jdbc2_fdw extension is used as an example (downloadable here).

1. Add a symlink from the shared object for your version of the JRE to /usr/lib/libjvm.so. For example:

   ln -s /usr/lib/jvm/java-6-openjdk/jre/lib/amd64/server/libjvm.so /usr/lib/libjvm.so
   

2. Start the build:

   make install USE_PGXS=1
   

Query Salesforce Marketing Data as a PostgreSQL Database

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

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

   CREATE EXTENSION jdbc2_fdw;
   

3. Create a server object for Salesforce Marketing:

   CREATE SERVER SFMarketingCloud 
   FOREIGN DATA WRAPPER jdbc2_fdw OPTIONS (
   drivername 'cdata.jdbc.sfmarketingcloud.SFMarketingCloudDriver',
   url 'jdbc:sfmarketingcloud:User=myUser;Password=myPassword;InitiateOAuth=GETANDREFRESH',
   querytimeout '15',
   jarfile '/home/MyUser/CData/CData\ JDBC\ Driver\ for\ Salesforce MyDriverEdition/lib/cdata.jdbc.sfmarketingcloud.jar'); 
   

4. Create a user mapping for the username and password of a user known to the MySQL daemon.

   CREATE USER MAPPING for postgres SERVER SFMarketingCloud OPTIONS (
   username 'admin', 
   password 'test');
   

5. Create a foreign table in your local database:

   postgres=# CREATE FOREIGN TABLE subscriber (
   subscriber_id text,
   subscriber_Id text,
   subscriber_Status numeric) 
   SERVER SFMarketingCloud OPTIONS (
   table_name 'subscriber');
   

postgres=# SELECT * FROM subscriber;
