Use the Remoting features of the Drip 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 Drip data as a PostgreSQL database, use the CData JDBC Driver for Drip and a JDBC foreign data wrapper (FDW). In this article, we compile the FDW, install it, and query Drip data from PostgreSQL Server.
Connect to Drip Data as a JDBC Data Source
To connect to Drip 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.api.APIDriver
- JDBC URL:
The URL must start with "jdbc:api:" and can include any of the connection properties in name-value pairs separated with semicolons.
Start by setting the Profile connection property to the location of the Drip Profile on disk (e.g. C:\profiles\Drip.apip). Next, set the ProfileSettings connection property to the connection string for Drip (see below).
Drip API Profile Settings
To use Token Authentication, specify your APIKey within the ProfileSettings connection property. The APIKey should be set to your Drip personal API Token.
Built-in Connection String Designer
For assistance in constructing the JDBC URL, use the connection string designer built into the Drip JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.
java -jar cdata.jdbc.api.jar
Fill in the connection properties and copy the connection string to the clipboard.
A typical JDBC URL is below:
jdbc:api:Profile=C:\profiles\Drip.apip;ProfileSettings='APIKey=my_api_token';
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).
- 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
- Start the build:
make install USE_PGXS=1
Query Drip Data as a PostgreSQL Database
After you have installed the extension, follow the steps below to start executing queries to Drip data:
- Log into your database.
-
Load the extension for the database:
CREATE EXTENSION jdbc2_fdw;
-
Create a server object for Drip:
CREATE SERVER API FOREIGN DATA WRAPPER jdbc2_fdw OPTIONS ( drivername 'cdata.jdbc.api.APIDriver', url 'jdbc:api:Profile=C:\profiles\Drip.apip;ProfileSettings='APIKey=my_api_token';', querytimeout '15', jarfile '/home/MyUser/CData/CData\ JDBC\ Driver\ for\ Salesforce MyDriverEdition/lib/cdata.jdbc.api.jar');
-
Create a user mapping for the username and password of a user known to the MySQL daemon.
CREATE USER MAPPING for postgres SERVER API OPTIONS ( username 'admin', password 'test');
-
Create a foreign table in your local database:
postgres=# CREATE FOREIGN TABLE broadcasts ( broadcasts_id text, broadcasts_Id text, broadcasts_Name numeric) SERVER API OPTIONS ( table_name 'broadcasts');
postgres=# SELECT * FROM broadcasts;
