SQL Gateway とODBC Driver を使ってBusiness b-ridge 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、Business b-ridge のMySQL Federated Table を構築できます。CData ODBC Driver for Business b-ridge 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。Business b-ridge data をMySQL テーブルのように使いましょう。

Business b-ridge 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.

When connecting to Business b-ridge, CompanyKey, ProjectKey, and SubscriptionKey are required.

To obtain the SubscriptionKey, follow the steps below:

  • Log in to Business b-ridge API Protal and go to "Profile" in the "Your name" menu.
  • In your subscription section click "Main Key" to retrieve their respective values.

Authenticate to Business b-ridge Account

Set the following connection properties to connect:

  • CompanyKey: Set the Business b-ridge Company Key of the connection destination.
  • ProjectKey: Set the Business b-ridge Project Key of the connection destination.
  • SubscriptionKey: Set the value "Subscription Key".

SQL Gateway の設定

See the SQL Gateway Overview to set up connectivity to Business b-ridge 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.

Business b-ridge 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 Business b-ridge. 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 fedBusinessBridge
FOREIGN DATA WRAPPER mysql
OPTIONS (USER 'sql_gateway_user', PASSWORD 'sql_gateway_passwd', HOST 'sql_gateway_host', PORT ####, DATABASE 'CData BusinessBridge 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 (CDATA). Refer to the following template for the statement to create a FEDERATED table:

CREATE TABLE fed_cdata (
  ...,
  itemid  TYPE(LEN),
  structureid  TYPE(LEN),
  ...,
)
ENGINE=FEDERATED
DEFAULT CHARSET=latin1
CONNECTION='fedBusinessBridge/cdata';

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 Business b-ridge 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 Business b-ridge. Refer to the following example:

SELECT 
  fed_cdata.itemid, 
  local_table.custom_field 
FROM 
  local_table 
JOIN 
  fed_cdata 
ON 
  local_table.foreign_itemid = fed_cdata.itemid;
