Connect to SAP Hybris C4C as an External Data Source using PolyBase

PolyBase for SQL Server allows you to query external data by using the same Transact-SQL syntax used to query a database table. When paired with the CData ODBC Driver for SAP Hybris C4C, you get access to your SAP Hybris C4C data directly alongside your SQL Server data. This article describes creating an external data source and external tables to grant access to live SAP Hybris C4C data using T-SQL queries.

NOTE: PolyBase is only available on SQL Server 19 and above, and only for Standard SQL Server.

The CData ODBC drivers offer unmatched performance for interacting with live SAP Hybris C4C data using PolyBase due to optimized data processing built into the driver. When you issue complex SQL queries from SQL Server to SAP Hybris C4C, the driver pushes down supported SQL operations, like filters and aggregations, directly to SAP Hybris C4C and utilizes the embedded SQL engine to process unsupported operations (often SQL functions and JOIN operations) client-side. And with PolyBase, you can also join SQL Server data with SAP Hybris C4C data, using a single query to pull data from distributed sources.

Connect to SAP Hybris C4C

If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs. To create an external data source in SQL Server using PolyBase, configure a System DSN (CData SAP Hybris C4C Sys is created automatically).

SAP Hybris Cloud for Customer uses basic authentication. Set the User and Password to your login credentials.

Click "Test Connection" to ensure that the DSN is connected to SAP Hybris C4C properly. Navigate to the Tables tab to review the table definitions for SAP Hybris C4C.

Create an External Data Source for SAP Hybris C4C Data

After configuring the connection, you need to create a master encryption key and a credential database for the external data source.

Creating a Master Encryption Key

Execute the following SQL command to create a new master key, 'ENCRYPTION,' to encrypt the credentials for the external data source.

CREATE MASTER KEY ENCRYPTION BY PASSWORD = 'password';

Creating a Credential Database

Execute the following SQL command to create credentials for the external data source connected to SAP Hybris C4C data.

NOTE: IDENTITY and SECRET correspond with the User and Password properties for SAP Hybris C4C.

CREATE DATABASE SCOPED CREDENTIAL saphybrisc4c_creds
WITH IDENTITY = 'saphybrisc4c_username', SECRET = 'saphybrisc4c_password';

Create an External Data Source for SAP Hybris C4C

Execute a CREATE EXTERNAL DATA SOURCE SQL command to create an external data source for SAP Hybris C4C with PolyBase:

• Set the LOCATION parameter , using the DSN and credentials configured earlier.

For SAP Hybris C4C, set SERVERNAME to the URL or address for your server (e.g. 'localhost' or '127.0.0.1' for local servers; the remote URL for remote servers). Leave PORT empty. PUSHDOWN is set to ON by default, meaning the ODBC Driver can leverage server-side processing for complex queries.

CREATE EXTERNAL DATA SOURCE cdata_saphybrisc4c_source
WITH ( 
  LOCATION = 'odbc://SERVER_URL',
  CONNECTION_OPTIONS = 'DSN=CData SAP Hybris C4C Sys',
  -- PUSHDOWN = ON | OFF,
  CREDENTIAL = saphybrisc4c_creds
);

Create External Tables for SAP Hybris C4C

After creating the external data source, use CREATE EXTERNAL TABLE statements to link to SAP Hybris C4C data from your SQL Server instance. The table column definitions must match those exposed by the CData ODBC Driver for SAP Hybris C4C. You can refer to the Tables tab of the DSN Configuration Wizard to see the table definition.

Sample CREATE TABLE Statement

The statement to create an external table based on a SAP Hybris C4C AccountCollection would look similar to the following:

CREATE EXTERNAL TABLE AccountCollection(
  ObjectID [nvarchar](255) NULL,
  AccountName [nvarchar](255) NULL,
  ...
) WITH ( 
  LOCATION='AccountCollection',
  DATA_SOURCE=cdata_saphybrisc4c_source
);

Having created external tables for SAP Hybris C4C in your SQL Server instance, you are now able to query local and remote data simultaneously. Thanks to built-in query processing in the CData ODBC Driver, you know that as much query processing as possible is being pushed to SAP Hybris C4C, freeing up local resources and computing power.
