RazorSQL からAzure Data Lake Storage データに連携。

CData JDBC Driver for ADLS を使って、各種ツールからAzure Data Lake Storage データにアクセスすることが可能になります。本記事では、Azure Data Lake Storage データにRazorSQL のウィザードから連携利用する方法を紹介します。

Azure Data Lake Storage JDBC Data Source　の設定

1. RazorSQL アプリケーションを開いて、Connections メニューから、Add Connection Profile -> Other -> JDBC にナビゲートします。
2. Connection Wizard で、以下を設定します：
   • Driver Location:JDBC Driver のインストールディレクトリのlib サブフォルダに設定します。
   • Driver Class:　ドライバークラスを cdata.jdbc.adls.ADLSDriver に設定します。
   • Username:ユーザー名。（ユーザー名をブランクにして、JDBC URL 内で設定することも可能です。）
   • Password:パスワード。（ユーザー名をブランクにして、JDBC URL 内で設定することも可能です。）

   • JDBC URL:接続パラメータを入力します：jdbc:adls: から始まるJDBC URL を入力します。接続プロパティをカンマ区切りで書きます。

     Authenticating to a Gen 1 DataLakeStore Account

     Gen 1 uses OAuth 2.0 in Azure AD for authentication.

     For this, an Active Directory web application is required. You can create one as follows:

     1. Sign in to your Azure Account through the .
     2. Select "Azure Active Directory".
     3. Select "App registrations".
     4. Select "New application registration".
     5. Provide a name and URL for the application. Select Web app for the type of application you want to create.
     6. Select "Required permissions" and change the required permissions for this app. At a minimum, "Azure Data Lake" and "Windows Azure Service Management API" are required.
     7. Select "Key" and generate a new key. Add a description, a duration, and take note of the generated key. You won't be able to see it again.

     To authenticate against a Gen 1 DataLakeStore account, the following properties are required:

     • Schema: Set this to ADLSGen1.
     • Account: Set this to the name of the account.
     • OAuthClientId: Set this to the application Id of the app you created.
     • OAuthClientSecret: Set this to the key generated for the app you created.
     • TenantId: Set this to the tenant Id. See the property for more information on how to acquire this.
     • Directory: Set this to the path which will be used to store the replicated file. If not specified, the root directory will be used.

     Authenticating to a Gen 2 DataLakeStore Account

     To authenticate against a Gen 2 DataLakeStore account, the following properties are required:

     • Schema: Set this to ADLSGen2.
     • Account: Set this to the name of the account.
     • FileSystem: Set this to the file system which will be used for this account.
     • AccessKey: Set this to the access key which will be used to authenticate the calls to the API. See the property for more information on how to acquire this.
     • Directory: Set this to the path which will be used to store the replicated file. If not specified, the root directory will be used.

     一般的なURL ：:

     jdbc:adls:Schema=ADLSGen2;Account=myAccount;FileSystem=myFileSystem;AccessKey=myAccessKey;

Azure Data Lake Storage からテーブルを選択してクエリを実行

接続を確立後、Wizard が閉じ、接続はコネクションパネルで接続が利用可能になります。テーブルをクエリしてみます。
