Connect to SAP ByDesign Data as a Federated Tables in MySQL

Use the CData Cloud Hub to set up federated tables for SAP ByDesign data in MySQL .

You can use the CData Cloud Hub to set up federated tables in MySQL for SAP ByDesign data. The Cloud Hub provides a MySQL interface for SAP ByDesign: After configuring a virtual MySQL database for SAP ByDesign, you can create a server and tables using the FEDERATED Storage Engine in MySQL. You can then work with SAP ByDesign data just as you would local MySQL tables.

The CData Cloud Hub provides a pure MySQL, cloud-to-cloud interface for SAP ByDesign, allowing you to easily query live SAP ByDesign data alongside existing MySQL data — all without replicating the data. Using optimized data processing out of the box, the CData Cloud Hub pushes all supported SQL operations (filters, JOINs, etc) directly to SAP ByDesign, leveraging server-side processing to quickly return SAP ByDesign data.

Create a Virtual MySQL Database for SAP ByDesign Data

CData Cloud Hub uses a straightforward, point-and-click interface to connect to data sources and generate APIs.

  1. Login to Cloud Hub and click Databases.
  2. Select "SAP ByDesign" from Available Data Sources.
  3. Enter the necessary authentication properties to connect to SAP ByDesign.

    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.
  4. Click Test Database.
  5. Click Privileges -> Add and add the new user (or an existing user) with the appropriate permissions.

With the virtual database created, you are ready to connect to SAP ByDesign data from any MySQL client.

Create a FEDERATED Server and Tables for SAP ByDesign Data

After you have configured and started the service, create a FEDERATED server to simplify the process of creating FEDERATED tables:

Create a FEDERATED Server

The following statement will create a FEDERATED server based on the Cloud Hub. Note that the username and password of the FEDERATED server must match a user account you defined on the Cloud Hub.

CREATE SERVER fedSAPByDesign
FOREIGN DATA WRAPPER mysql
OPTIONS (USER 'cloud_hub_user', PASSWORD 'cloud_hub_passwd', HOST 'myinstance.cdatacloud.net', PORT 3306, DATABASE 'sapbydesigndb');

Create a FEDERATED Table

To create a FEDERATED table using our newly created server, use the CONNECTION keyword and pass the name of the FEDERATED server and the remote table ([Inventory Balance]). Refer to the following template for the statement to create a FEDERATED table:

CREATE TABLE fed_[inventory balance] (
  ...,
  id  TYPE(LEN),
  productcategoryid  TYPE(LEN),
  ...,
)
ENGINE=FEDERATED
DEFAULT CHARSET=utf8
CONNECTION='fedSAPByDesign/[Inventory Balance]';

NOTE: The table schema for the FEDERATED table must match the remote table schema exactly. You can always connect directly to the Cloud Hub using any MySQL client and run SHOW COLUMNS FROM [Inventory Balance] to get the table schema.

Execute Queries

You can now execute queries to the SAP ByDesign FEDERATED tables from any tool that can connect to MySQL, which is particularly useful if you need to JOIN data from a local table with data from SAP ByDesign. Refer to the following example:

SELECT 
  fed_[inventory balance].id, 
  local_table.custom_field 
FROM 
  local_table 
JOIN 
  fed_[inventory balance] 
ON 
  local_table.foreign_id = fed_[inventory balance].id;
