A PostgreSQL Interface for Dynamics CRM Data

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

Connect to Dynamics CRM Data as a JDBC Data Source

To connect to Dynamics CRM 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.dynamicscrm.DynamicsCRMDriver

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

  The connection string options meet the authentication and connection requirements of different Dynamics CRM instances. To connect to your instance, set the User and Password properties, under the Authentication section, to valid Dynamics CRM user credentials and set the Url to a valid Dynamics CRM server organization root. Additionally, set the CRMVersion property to 'CRM2011+' or 'CRMOnline'. IFD configurations are supported as well; set InternetFacingDeployment to true.

  Additionally, you can provide the security token service (STS) or AD FS endpoint in the STSURL property. This value can be retrieved with the GetSTSUrl stored procedure. Office 365 users can connect to the default STS URL by simply setting CRMVersion.

  Built-in Connection String Designer

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

  java -jar cdata.jdbc.dynamicscrm.jar

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

  A typical JDBC URL is below:

  jdbc:dynamicscrm:User=myuseraccount;Password=mypassword;URL=https://myOrg.crm.dynamics.com/;CRM Version=CRM Online;

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 Dynamics CRM Data as a PostgreSQL Database

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

1. Log into your database.
2. Load the extension for the database: CREATE EXTENSION jdbc2_fdw;
3. Create a server object for Dynamics CRM: CREATE SERVER DynamicsCRM FOREIGN DATA WRAPPER jdbc2_fdw OPTIONS ( drivername 'cdata.jdbc.dynamicscrm.DynamicsCRMDriver', url 'jdbc:dynamicscrm:User=myuseraccount;Password=mypassword;URL=https://myOrg.crm.dynamics.com/;CRM Version=CRM Online;', querytimeout '15', jarfile '/home/MyUser/CData/CData\ JDBC\ Driver\ for\ Salesforce MyDriverEdition/lib/cdata.jdbc.dynamicscrm.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 DynamicsCRM OPTIONS ( username 'admin', password 'test');
5. Create a foreign table in your local database: postgres=# CREATE FOREIGN TABLE account ( account_id text, account_FirstName text, account_NumberOfEmployees numeric) SERVER DynamicsCRM OPTIONS ( table_name 'account');
