MySQL のFederated Table としてMYOB AccountRight データを連携利用する

SQL Gateway を使って、MySQL リモーティングサービスを作成し、MYOB AccountRight のMySQL Federated Table を構築できます。CData ODBC Driver for MYOB AccountRight のMySQL インターフェースのdeamon になります。サービス起動後、MySQL のFEDERATED ストレージエンジンを使ってサーバーおよびテーブルを作成します。MYOB AccountRight data をMySQL テーブルのように使いましょう。

MYOB AccountRight データへの接続

If you have not already done so, provide values for the required connection properties in the data source name (DSN). You can use the built-in Microsoft ODBC Data Source Administrator to configure the DSN. This is also the last step of the driver installation. See the "Getting Started" chapter in the help documentation for a guide to using the Microsoft ODBC Data Source Administrator to create and configure a DSN.

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.

SQL Gateway の設定

See the SQL Gateway Overview to set up connectivity to MYOB AccountRight data as a virtual MySQL database. You will configure a MySQL remoting service that listens for MySQL requests from clients. The service can be configured in the SQL Gateway UI.

MYOB AccountRight Data のFEDERATED サーバーおよびテーブルを作成

After you have configured and started the service, create a FEDERATED server to simplify the process of creating FEDERATED tables:

FEDERATED サーバーの作成

The following statement will create a FEDERATED server based on the ODBC Driver for MYOB AccountRight. Note that the username and password of the FEDERATED server must match a user account you defined on the Users tab of the SQL Gateway.

CREATE SERVER fedMYOB
FOREIGN DATA WRAPPER mysql
OPTIONS (USER 'sql_gateway_user', PASSWORD 'sql_gateway_passwd', HOST 'sql_gateway_host', PORT ####, DATABASE 'CData MYOB Sys');

FEDERATED テーブルの作成

To create a FEDERATED table using our newly created server, use the CONNECTION keyword and pass the name of the FEDERATED server and the remote table (Accounts). Refer to the following template for the statement to create a FEDERATED table:

CREATE TABLE fed_accounts (
  ...,
  id  TYPE(LEN),
  name  TYPE(LEN),
  ...,
)
ENGINE=FEDERATED
DEFAULT CHARSET=latin1
CONNECTION='fedMYOB/accounts';

NOTE: The table schema for the FEDERATED table must match the remote table schema exactly. You can always connect directly to the MySQL remoting service using any MySQL client and run a SHOW CREATE TABLE query to get the table schema.

クエリの実行

You can now execute queries to the MYOB AccountRight FEDERATED tables from any tool that can connect to MySQL, which is particularly useful if you need to JOIN data from a local table with data from MYOB AccountRight. Refer to the following example:

SELECT 
  fed_accounts.id, 
  local_table.custom_field 
FROM 
  local_table 
JOIN 
  fed_accounts 
ON 
  local_table.foreign_id = fed_accounts.id;
