MySQL のFederated Table としてSage Cloud Accounting Data データを連携利用する

SQL Gateway とODBC Driver を使ってSage Cloud Accounting のMySQL Federated Table を構築する。

SQL Gateway を使って、MySQL リモーティングサービスを作成し、Sage Cloud Accounting のMySQL Federated Table を構築できます。CData ODBC Driver for Sage Cloud Accounting 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。Sage Cloud Accounting data をMySQL テーブルのように使いましょう。

Sage Cloud Accounting Data 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.

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.

SQL Gateway の設定

See the SQL Gateway Overview to set up connectivity to Sage Cloud Accounting 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.

Sage Cloud Accounting 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 Sage Cloud Accounting. 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 fedSageBCAccounting
FOREIGN DATA WRAPPER mysql
OPTIONS (USER 'sql_gateway_user', PASSWORD 'sql_gateway_passwd', HOST 'sql_gateway_host', PORT ####, DATABASE 'CData SageBCAccounting 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 (SalesInvoices). Refer to the following template for the statement to create a FEDERATED table:

CREATE TABLE fed_salesinvoices (
  ...,
  contact_name  TYPE(LEN),
  total_amount  TYPE(LEN),
  ...,
)
ENGINE=FEDERATED
DEFAULT CHARSET=latin1
CONNECTION='fedSageBCAccounting/salesinvoices';

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 Sage Cloud Accounting 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 Sage Cloud Accounting. Refer to the following example:

SELECT 
  fed_salesinvoices.contact_name, 
  local_table.custom_field 
FROM 
  local_table 
JOIN 
  fed_salesinvoices 
ON 
  local_table.foreign_contact_name = fed_salesinvoices.contact_name;
