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

Microsoft Project 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.

Authentication セクションのUser およびPassword プロパティを、有効なMicrosoft Project ユーザークレデンシャルに設定する 必要があります。加えて、URL を有効なMicrosoft Project サーバーの組織ルート、またはMicrosoft Project サービスのファイルに 指定する必要があります。

SQL Gateway の設定

See the SQL Gateway Overview to set up connectivity to Microsoft Project 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.

Microsoft Project 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 MicrosoftProject. 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 fedMicrosoftProject
FOREIGN DATA WRAPPER mysql
OPTIONS (USER 'sql_gateway_user', PASSWORD 'sql_gateway_passwd', HOST 'sql_gateway_host', PORT ####, DATABASE 'CData MicrosoftProject 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 (Projects). Refer to the following template for the statement to create a FEDERATED table:

CREATE TABLE fed_projects (
  ...,
  projectname  TYPE(LEN),
  projectactualcost  TYPE(LEN),
  ...,
)
ENGINE=FEDERATED
DEFAULT CHARSET=latin1
CONNECTION='fedMicrosoftProject/projects';

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 Microsoft Project 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 Microsoft Project. Refer to the following example:

SELECT
  fed_projects.projectname,
  local_table.custom_field
FROM
  local_table
JOIN
  fed_projects
ON
  local_table.foreign_projectname = fed_projects.projectname;
