MySQL のFederated Table としてTwilio の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、Twilio のMySQL Federated Table を構築できます。CData ODBC Driver for Twilio 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。Twilio のデータ をMySQL テーブルのように使いましょう。

Twilio のデータへの接続

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.

Twilio への接続

Auth Token

Auth Token およびAccount SID を使用して、Twilio に認証できます。

Twilio Console Dashboard を開き、Account Info セクションに移動して、以下の接続プロパティを設定します。

• AccountSID：Account SID フィールドの値。
• AuthToken：Auth Token フィールドの値。Show をクリックして非表示を解除します。

SQL Gateway の設定

See the SQL Gateway Overview to set up connectivity to Twilio のデータ 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.

Twilio データの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 Twilio. 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 fedTwilio
FOREIGN DATA WRAPPER mysql
OPTIONS (USER 'sql_gateway_user', PASSWORD 'sql_gateway_passwd', HOST 'sql_gateway_host', PORT ####, DATABASE 'CData Twilio 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 (Calls). Refer to the following template for the statement to create a FEDERATED table:

CREATE TABLE fed_calls (
  ...,
  to  TYPE(LEN),
  duration  TYPE(LEN),
  ...,
)
ENGINE=FEDERATED
DEFAULT CHARSET=latin1
CONNECTION='fedTwilio/calls';

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 Twilio 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 Twilio. Refer to the following example:

SELECT
  fed_calls.to,
  local_table.custom_field
FROM
  local_table
JOIN
  fed_calls
ON
  local_table.foreign_to = fed_calls.to;
