CDATAQUERY 関数を使って、Excel スプレッドシートにAthena dataを自動挿入

CDATAQUERY 関数を使ってデータ、スプレッドシートの任意のセルにAthena data データを自動挿入、編集、削除が可能に。

CData Excel Add-In for Athena の関数を使って、スプレッドシートにデータを取り込むことができます。下記の3つの手順では、次のタスクを自動化する方法について説明します:ユーザー定義の値でAthena data を検索し、その結果をExcel スプレッドシートに出力します。

CDATAQUERY 関数の構文は次のとおりです: =CDATAQUERY(Query, [Connection], [Parameters], [ResultLocation]);

この関数に入力する値は以下の3つです:

  • Query:取得したいAthena data レコードの宣言、もしくは修正を簡単な構文で記述。
  • Connection:AmazonAthenaConnection1 のような接続名、もしくは接続文字列を入力。接続文字列は、Athena data への接続に必要なプロパティのセミコロン区切りとなります。一般的な接続文字列は次のとおりです:
    • AccessKey
    • SecretKey
    • Region
    • Database
    • S3StagingDirectory

    Authenticating to Amazon Athena

    To authorize Amazon Athena requests, provide the credentials for an administrator account or for an IAM user with custom permissions: Set AccessKey to the access key Id. Set SecretKey to the secret access key.

    Note: Though you can connect as the AWS account administrator, it is recommended to use IAM user credentials to access AWS services.

    Obtaining the Access Key

    To obtain the credentials for an IAM user, follow the steps below:

    1. Sign into the IAM console.
    2. In the navigation pane, select Users.
    3. To create or manage the access keys for a user, select the user and then select the Security Credentials tab.

    To obtain the credentials for your AWS root account, follow the steps below:

    1. Sign into the AWS Management console with the credentials for your root account.
    2. Select your account name or number and select My Security Credentials in the menu that is displayed.
    3. Click Continue to Security Credentials and expand the Access Keys section to manage or create root account access keys.

    Authenticating from an EC2 Instance

    If you are using the CData Data Provider for Amazon Athena 2018 from an EC2 Instance and have an IAM Role assigned to the instance, you can use the IAM Role to authenticate. To do so, set UseEC2Roles to true and leave AccessKey and SecretKey empty. The CData Data Provider for Amazon Athena 2018 will automatically obtain your IAM Role credentials and authenticate with them.

    Authenticating as an AWS Role

    In many situations it may be preferable to use an IAM role for authentication instead of the direct security credentials of an AWS root user. An AWS role may be used instead by specifying the RoleARN. This will cause the CData Data Provider for Amazon Athena 2018 to attempt to retrieve credentials for the specified role. If you are connecting to AWS (instead of already being connected such as on an EC2 instance), you must additionally specify the AccessKey and SecretKey of an IAM user to assume the role for. Roles may not be used when specifying the AccessKey and SecretKey of an AWS root user.

    Authenticating with MFA

    For users and roles that require Multi-factor Authentication, specify the MFASerialNumber and MFAToken connection properties. This will cause the CData Data Provider for Amazon Athena 2018 to submit the MFA credentials in a request to retrieve temporary authentication credentials. Note that the duration of the temporary credentials may be controlled via the TemporaryTokenDuration (default 3600 seconds).

    Connecting to Amazon Athena

    In addition to the AccessKey and SecretKey properties, specify Database, S3StagingDirectory and Region. Set Region to the region where your Amazon Athena data is hosted. Set S3StagingDirectory to a folder in S3 where you would like to store the results of queries.

    If Database is not set in the connection, the data provider connects to the default database set in Amazon Athena.

  • ResultLocation:結果のアウトプットを開始するセル。

スプレッドシートのセルをクエリのインプットとして渡す

下記の処理では、すべての関数インプットをひとつ目のカラムでオーガナイズするスプレッドシートができます。

  1. 関数をインプットするセルを定義します。接続インプットに加えて、CustomerId のように、Athena data の検索に使われるフィルタ用の基準を定義する追加のインプットを入力します。
  2. 別のセルに、上で定義したユーザーインプットセルからセルの値を参照する関数をを書きます。住所などスペースを含む可能性のある値は、シングルクオートで囲みます。
  3. =CDATAQUERY("SELECT * FROM Customers WHERE CustomerId = '"&B6&"'","AccessKey="&B1&";SecretKey="&B2&";Region="&B3&";Database="&B4&";S3StagingDirectory="&B5&";Provider=AmazonAthena",B7)
  4. フィルタを変更してデータを変更します。
