Use the SQL Gateway and the ODBC Driver to set up federated tables for SAP ByDesign data in MySQL .
You can use the SQL Gateway to configure a MySQL remoting service and set up federated tables for SAP ByDesign data. The service is a daemon process that provides a MySQL interface to the CData ODBC Driver for SAP ByDesign: After you have started the service, 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.
Connect to SAP ByDesign Data
If you have not already done so, provide values for the required connection properties in the data source name (DSN). You can use the built-in Microsoft ODBC Data Source Administrator to configure the DSN. This is also the last step of the driver installation. See the "Getting Started" chapter in the help documentation for a guide to using the Microsoft ODBC Data Source Administrator to create and configure a DSN.
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.
Configure the SQL Gateway
See the SQL Gateway Overview to set up connectivity to SAP ByDesign data as a virtual MySQL database. You will configure a MySQL remoting service that listens for MySQL requests from clients. The service can be configured in the SQL Gateway UI.
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 ODBC Driver for SAP ByDesign. Note that the username and password of the FEDERATED server must match a user account you defined on the Users tab of the SQL Gateway.
CREATE SERVER fedSAPByDesign FOREIGN DATA WRAPPER mysql OPTIONS (USER 'sql_gateway_user', PASSWORD 'sql_gateway_passwd', HOST 'sql_gateway_host', PORT ####, DATABASE 'CData SAPByDesign Sys');
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=latin1 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 MySQL remoting service using any MySQL client and run a SHOW CREATE TABLE query 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;
