A PostgreSQL Interface for Bing Search Results

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

Connect to Bing Search Results as a JDBC Data Source

To connect to Bing Search 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.bing.BingDriver

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

  To connect to Bing, set the ApiKey connection property. To obtain the API key, sign into Microsoft Cognitive Services and register for the Bing Search APIs.

  Two API keys are then generated; select either one.

  When querying tables, the SearchTerms parameter must be supplied in the WHERE clause.

  Built-in Connection String Designer

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

  java -jar cdata.jdbc.bing.jar

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

  A typical JDBC URL is below:

  jdbc:bing:APIKey=MyAPIKey;

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 Bing Search Results as a PostgreSQL Database

After you have installed the extension, follow the steps below to start executing queries to Bing Search results:

1. Log into your database.
2. Load the extension for the database: CREATE EXTENSION jdbc2_fdw;
3. Create a server object for Bing Search: CREATE SERVER Bing FOREIGN DATA WRAPPER jdbc2_fdw OPTIONS ( drivername 'cdata.jdbc.bing.BingDriver', url 'jdbc:bing:APIKey=MyAPIKey;', querytimeout '15', jarfile '/home/MyUser/CData/CData\ JDBC\ Driver\ for\ Salesforce MyDriverEdition/lib/cdata.jdbc.bing.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 Bing OPTIONS ( username 'admin', password 'test');
5. Create a foreign table in your local database: postgres=# CREATE FOREIGN TABLE videosearch ( videosearch_id text, videosearch_Title text, videosearch_ViewCount numeric) SERVER Bing OPTIONS ( table_name 'videosearch');
