PolyBase で外部データソースとしてSage Cloud Accounting を連携利用

CData ODBC Driver for Sage Cloud Accounting とSQL Server 2019 のPolyBase を使って、リアルタイムSage Cloud Accounting data に外部データソースとしてアクセス。

SQL Server のPolyBase は、データベーステーブルをクエリするTransact-SQL シンタックスを使って、外部データにクエリする仕組みです。 CData ODBC Drivers for Sage Cloud Accounting data を組み合わせて使うことで、SQL Server データと同じようにSage Cloud Accounting data へのアクセスが可能です。 本記事では、PolyBase 外部データソースへのSage Cloud Accounting data の設定から、T-SQL クエリを使ったSage Cloud Accounting data へのアクセスを行います。

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

Sage Cloud Accounting への接続

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 Sage Cloud Accounting Sys is created automatically).

You can connect to Sage Business Cloud Accounting using the embedded OAuth connectivity. When you connect, the OAuth endpoint opens in your browser. Log in and grant permissions to complete the OAuth process. See the OAuth section in the online Help documentation for more information on other OAuth authentication flows.

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

Sage Cloud Accounting Data の外部データソースの作成

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.


Creating a Credential Database

Execute the following SQL command to create credentials for the external data source connected to Sage Cloud Accounting data.

NOTE: Since Sage Cloud Accounting does not require a User or Password to authenticate, you may use whatever values you wish for IDENTITY and SECRET.

WITH IDENTITY = 'username', SECRET = 'password';

Create an External Data Source for Sage Cloud Accounting

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

For Sage Cloud Accounting, set SERVERNAME to 'localhost' or '' 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_sagebcaccounting_source
  CONNECTION_OPTIONS = 'DSN=CData Sage Cloud Accounting Sys',
  CREDENTIAL = sagebcaccounting_creds

Sage Cloud Accounting のExternal Table を作成

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

  contact_name [nvarchar](255) NULL,
  total_amount [nvarchar](255) NULL,
) WITH ( 

Having created external tables for Sage Cloud Accounting 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 Sage Cloud Accounting, freeing up local resources and computing power.
