Connect to Odoo as an External Data Source using PolyBase

Use the CData ODBC Driver for Odoo and PolyBase to create an external data source in SQL Server 2019 with access to live Odoo 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 ODBC Driver for Odoo, you get access to your Odoo data directly alongside your SQL Server data. This article walks through creating an external data source and external tables to grant access to live Odoo data using T-SQL queries.

The CData ODBC drivers offer unmatched performance for interacting with live Odoo data using PolyBase due to optimized data processing built into the driver. When you issue complex SQL queries from SQL Server to Odoo, the driver pushes down supported SQL operations, like filters and aggregations, directly to Odoo 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 Odoo data, using a single query to pull data from distributed sources.

Connect to Odoo

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 Odoo Sys is created automatically).

To connect, set the Url to a valid Odoo site, User and Password to the connection details of the user you are connecting with, and Database to the Odoo database.

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

Create an External Data Source for Odoo 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 Odoo data.

NOTE: IDENTITY and SECRET correspond with the User and Password properties for Odoo.

CREATE DATABASE SCOPED CREDENTIAL odoo_creds
WITH IDENTITY = 'username', SECRET = 'password';

Create an External Data Source for Odoo

Execute the following SQL command to create an external data source for Odoo with PolyBase, using the DSN and credentials configured earlier.

For Odoo, set SERVERNAME to 'localhost' or '127.0.0.1' and 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_odoo_source
WITH ( 
  LOCATION = 'odbc://SERVERNAME[:PORT]',
  CONNECTION_OPTIONS = 'DSN=CData Odoo Sys',
  -- PUSHDOWN = ON | OFF,
  CREDENTIAL = odoo_creds
);

Create External Tables for Odoo

After creating the external data source, use CREATE EXTERNAL TABLE statements to link to Odoo data from your SQL Server instance. The table column definitions must match those exposed by the CData ODBC Driver for Odoo. 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 Odoo res_users would look similar to the following:

CREATE EXTERNAL TABLE res_users(
  name [nvarchar](255) NULL,
  email [nvarchar](255) NULL,
  ...
) WITH ( 
  LOCATION='res_users',
  DATA_SOURCE=cdata_odoo_source
);

Having created external tables for Odoo 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 Odoo, freeing up local resources and computing power.
