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

Connect to Reckon Accounts Hosted Data as a JDBC Data Source

To connect to Reckon Accounts Hosted 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.reckonaccountshosted.ReckonAccountsHostedDriver
  

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

  The connector makes requests to Reckon Accounts Hosted through OAuth. Specify the following connection properties:

  • SubscriptionKey: Required. You get this value when you created your developer account.
  • CountryVersion: Defaults to 2021.R2.AU.
  • CompanyFile: Required. The path to the company file.
  • User: Required. The username of the company file.
  • Password: Required. The password of the company file.
  • InitiateOAuth: Set this to GETANDREFRESH to let the driver handle access tokens.
  • CallbackURL: The redirectURI of your Custom OAuth App.
  • OAuthClientId: The client id of your Custom OAuth App.
  • OAuthClientSecret: The client secret of your Custom OAuth App.

  CData provides an embedded OAuth application that simplifies OAuth desktop authentication. See the Help documentation for information on other OAuth authentication methods (web, headless, etc.), creating custom OAuth applications, and reasons for doing so.

  Built-in Connection String Designer

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

  java -jar cdata.jdbc.reckonaccountshosted.jar
  

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

  A typical JDBC URL is below:

  jdbc:reckonaccountshosted:SubscriptionKey=my_subscription_key;CountryVersion=2021.R2.AU;CompanyFile=Q:/CompanyName.QBW;User=my_user;Password=my_password;CallbackURL=http://localhost:33333;OAuthClientId=my_oauth_client_id;OAuthClientSecret=my_oauth_client_secret;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 Reckon Accounts Hosted Data as a PostgreSQL Database

After you have installed the extension, follow the steps below to start executing queries to Reckon Accounts Hosted data:

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

   CREATE EXTENSION jdbc2_fdw;
   

3. Create a server object for Reckon Accounts Hosted:

   CREATE SERVER ReckonAccountsHosted 
   FOREIGN DATA WRAPPER jdbc2_fdw OPTIONS (
   drivername 'cdata.jdbc.reckonaccountshosted.ReckonAccountsHostedDriver',
   url 'jdbc:reckonaccountshosted:SubscriptionKey=my_subscription_key;CountryVersion=2021.R2.AU;CompanyFile=Q:/CompanyName.QBW;User=my_user;Password=my_password;CallbackURL=http://localhost:33333;OAuthClientId=my_oauth_client_id;OAuthClientSecret=my_oauth_client_secret;InitiateOAuth=GETANDREFRESH;',
   querytimeout '15',
   jarfile '/home/MyUser/CData/CData\ JDBC\ Driver\ for\ Salesforce MyDriverEdition/lib/cdata.jdbc.reckonaccountshosted.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 ReckonAccountsHosted OPTIONS (
   username 'admin', 
   password 'test');
   

5. Create a foreign table in your local database:

   postgres=# CREATE FOREIGN TABLE accounts (
   accounts_id text,
   accounts_Name text,
   accounts_Balance numeric) 
   SERVER ReckonAccountsHosted OPTIONS (
   table_name 'accounts');
   

You can now execute read/write commands to Reckon Accounts Hosted:

postgres=# SELECT * FROM accounts;
