Use CData drivers and PolyBase to create an external data source in SQL Server 2019 with access to live Shippo data.
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 API Driver for ODBC, you get access to your Shippo data directly alongside your SQL Server data. This article describes creating an external data source and external tables to grant access to live Shippo 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 Shippo data using PolyBase due to optimized data processing built into the driver. When you issue complex SQL queries from SQL Server to Shippo, the driver pushes down supported SQL operations, like filters and aggregations, directly to Shippo 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 Shippo data, using a single query to pull data from distributed sources.
Connect to Shippo
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 Shippo Sys is created automatically).
Start by setting the Profile connection property to the location of the Shippo Profile on disk (e.g. C:\profiles\Shippo.apip). Next, set the ProfileSettings connection property to the connection string for Shippo (see below).
Shippo API Profile Settings
In order to authenticate to Shippo, you will need an API Key. You can find this API key under 'Settings' > 'API' > 'Generate Token'. After generating your key, set it to the APIKey in ProfileSettings connection property.
Click "Test Connection" to ensure that the DSN is connected to Shippo properly. Navigate to the Tables tab to review the table definitions for Shippo.
Create an External Data Source for Shippo 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 Shippo data.
NOTE: Since Shippo does not require a User or Password to authenticate, you may use whatever values you wish for IDENTITY and SECRET.
CREATE DATABASE SCOPED CREDENTIAL api_creds WITH IDENTITY = 'username', SECRET = 'password';
Create an External Data Source for Shippo
Execute a CREATE EXTERNAL DATA SOURCE SQL command to create an external data source for Shippo with PolyBase:
- Set the LOCATION parameter , using the DSN and credentials configured earlier.
For Shippo, 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_api_source WITH ( LOCATION = 'odbc://SERVER_URL', CONNECTION_OPTIONS = 'DSN=CData Shippo Sys', -- PUSHDOWN = ON | OFF, CREDENTIAL = api_creds );
Create External Tables for Shippo
After creating the external data source, use CREATE EXTERNAL TABLE statements to link to Shippo data from your SQL Server instance. The table column definitions must match those exposed by the CData API Driver for ODBC. 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 Shippo Orders would look similar to the following:
CREATE EXTERNAL TABLE Orders( ObjectId [nvarchar](255) NULL, OrderStatus [nvarchar](255) NULL, ... ) WITH ( LOCATION='Orders', DATA_SOURCE=cdata_api_source );
Having created external tables for Shippo 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 Shippo, freeing up local resources and computing power.
