A PostgreSQL Interface for Microsoft Teams Data

Use the Remoting features of the Microsoft Teams JDBC Driver to create a PostgreSQL entry-point for data access.

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

Connect to Microsoft Teams Data as a JDBC Data Source

To connect to Microsoft Teams 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.msteams.MSTeamsDriver

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

    You can connect to MS Teams using the embedded OAuth connectivity. When you connect, the MS Teams OAuth endpoint opens in your browser. Log in and grant permissions to complete the OAuth process. See the OAuth section in the online Help documentation for more information on other OAuth authentication flows.

    Built-in Connection String Designer

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

    java -jar cdata.jdbc.msteams.jar

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

    A typical JDBC URL is below:

    jdbc:msteams:OAuthClientId=MyApplicationId;OAuthClientSecret=MySecretKey;CallbackURL=http://localhost:33333;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.

  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 Microsoft Teams Data as a PostgreSQL Database

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

  1. Log into your database.
  2. Load the extension for the database: CREATE EXTENSION jdbc2_fdw;
  3. Create a server object for Microsoft Teams: CREATE SERVER MSTeams FOREIGN DATA WRAPPER jdbc2_fdw OPTIONS ( drivername 'cdata.jdbc.msteams.MSTeamsDriver', url 'jdbc:msteams:OAuthClientId=MyApplicationId;OAuthClientSecret=MySecretKey;CallbackURL=http://localhost:33333;InitiateOAuth=GETANDREFRESH', querytimeout '15', jarfile '/home/MyUser/CData/CData\ JDBC\ Driver\ for\ Salesforce MyDriverEdition/lib/cdata.jdbc.msteams.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 MSTeams OPTIONS ( username 'admin', password 'test');
  5. Create a foreign table in your local database: postgres=# CREATE FOREIGN TABLE teams ( teams_id text, teams_subject text, teams_location_displayName numeric) SERVER MSTeams OPTIONS ( table_name 'teams');
You can now execute read/write commands to Microsoft Teams: postgres=# SELECT * FROM teams;
