A PostgreSQL Interface for SAP ByDesign Data

Use the Remoting features of the SAP ByDesign 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 SAP ByDesign data as a PostgreSQL database, use the CData JDBC Driver for SAP ByDesign and a JDBC foreign data wrapper (FDW). In this article, we compile the FDW, install it, and query SAP ByDesign data from PostgreSQL Server.

Connect to SAP ByDesign Data as a JDBC Data Source

To connect to SAP ByDesign 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.sapbydesign.SAPByDesignDriver

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

    Set the following connection properties to connect to SAP ByDesign.

    • Url: Set this to the Url of your SAP ByDesign site. For example, https://test.sapbydesign.com
    • User: Set this to the username of your account.
    • Password: Set this to the password of your account.
    • CustomService or AnalyticsService: Only one of these must be specified. If you have a custom service you want to retrieve data from, specify CustomService. If you want to retrieve the reports of a analytical service, specify AnalyticsService.
      If neither is specified, 'cc_home_analytics.svc' will used as a default for the AnalyticsService property. If you are not sure what service to specify, you can always query the Services view to list available services.

    Built-in Connection String Designer

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

    java -jar cdata.jdbc.sapbydesign.jar

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

    A typical JDBC URL is below:

    jdbc:sapbydesign:URL=https://my999999.sapbydesign.com;User=username;Password=password;CustomService=servicename;

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 SAP ByDesign Data as a PostgreSQL Database

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

  1. Log into your database.
  2. Load the extension for the database: CREATE EXTENSION jdbc2_fdw;
  3. Create a server object for SAP ByDesign: CREATE SERVER SAPByDesign FOREIGN DATA WRAPPER jdbc2_fdw OPTIONS ( drivername 'cdata.jdbc.sapbydesign.SAPByDesignDriver', url 'jdbc:sapbydesign:URL=https://my999999.sapbydesign.com;User=username;Password=password;CustomService=servicename;', querytimeout '15', jarfile '/home/MyUser/CData/CData\ JDBC\ Driver\ for\ Salesforce MyDriverEdition/lib/cdata.jdbc.sapbydesign.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 SAPByDesign OPTIONS ( username 'admin', password 'test');
  5. Create a foreign table in your local database: postgres=# CREATE FOREIGN TABLE [inventory balance] ( [inventory balance]_id text, [inventory balance]_ID text, [inventory balance]_ProductCategoryID numeric) SERVER SAPByDesign OPTIONS ( table_name '[inventory balance]');
You can now execute SELECT commands to SAP ByDesign: postgres=# SELECT * FROM [inventory balance];
