Connect to MYOB AccountRight as an External Data Source using PolyBase

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

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

Connect to MYOB AccountRight

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 MYOB AccountRight Sys is created automatically).

These properties are required when connecting to a company file (both for Cloud and On-Premise instances).

  • CompanyFileId: You can find this by starting MYOB, opening your data file, and selecting Help -> About MYOB
  • User: The username associated with your company file.
  • Password: The password associated with your company file.

Connecting to a Cloud Instance

To connect to a cloud instance of MYOB, you can use the embedded OAuth credentials or create an OAuth app with MYOB. This process is detailed in the Help documentation.

Connecting to an On-Premise instance:

When connecting to an on-premise instance, you will need to set the following connection property in addition to those above:

  • InitiateOauth: Set this to OFF.
  • Url: The Url of your MYOB instance.

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

Create an External Data Source for MYOB AccountRight 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 MYOB AccountRight data.

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

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

Create an External Data Source for MYOB AccountRight

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

For MYOB AccountRight, 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_myob_source
WITH ( 
  LOCATION = 'odbc://SERVERNAME[:PORT]',
  CONNECTION_OPTIONS = 'DSN=CData MYOB AccountRight Sys',
  -- PUSHDOWN = ON | OFF,
  CREDENTIAL = myob_creds
);

Create External Tables for MYOB AccountRight

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

CREATE EXTERNAL TABLE Accounts(
  Id [nvarchar](255) NULL,
  Name [nvarchar](255) NULL,
  ...
) WITH ( 
  LOCATION='Accounts',
  DATA_SOURCE=cdata_myob_source
);

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