SQL Server Driver

Microsoft SQL Server 連携のパワフルなJava アプリケーションを素早く作成して配布。



Use the CData JDBC Driver for SQL Server to create a virtual data source for SQL Server data in the Denodo Virtual DataPort Administrator.

Denodo Platform is a data virtualization product providing a single point of contact for enterprise database data. When paired with the CData JDBC Driver for SQL Server, Denodo users can work with live SQL Server data alongside other enterprise data sources. This article walks through creating a virtual data source for SQL Server in the Denodo Virtual DataPort Administrator.

With built-in optimized data processing, the CData JDBC Driver offers unmatched performance for interacting with live SQL Server data. When you issue complex SQL queries to SQL Server, the driver pushes supported SQL operations, like filters and aggregations, directly to SQL Server and utilizes the embedded SQL engine to process unsupported operations client-side (often SQL functions and JOIN operations). Its built-in dynamic metadata querying allows you to work with and analyze SQL Server data using native data types.

Create a SQL Server Virtual Port

To connect to live SQL Server data from Denodo, you need to copy the JDBC Driver JAR file to the external library directory for Denodo and create a new JDBC Data Source from the Virtual DataPort Administrator tool.

  1. Download the CData JDBC Driver for SQL Server installer, unzip the package, and run the JAR file to install the driver.
  2. Copy the JAR File (and license file if it exists) from the installation location (typically C:\Program Files\CData\CData JDBC Driver for SQL Server\lib\) to the Denodo external library directory (C:\Denodo\Denodo Platform\lib-external\jdbc-drivers\cdata-sql-19).
  3. Open the Denodo Virtual DataPort Administrator tool and navigate to the Server Explorer tab.
  4. Right-click "admin" and select New -> Data source -> JDBC.
  5. Configure the JDBC Connection:
    • Name: your choice, e.g.: sql
    • Database adapter: Generic
    • Driver class path: C:\Denodo\Denodo Platform\lib-external\jdbc-drivers\cdata-sql-19
    • Driver class: cdata.jdbc.sql.SQLDriver
    • Database URI: Set this to a JDBC URL using the necessary connection properties. For example,

      jdbc:sql:User=myUser;Password=myPassword;Database=NorthWind;Server=myServer;Port=1433;

      Information on creating the Database URI follows:

      Built-In Connection String Designer

      For assistance in constructing the JDBC URL, use the connection string designer built into the SQL Server JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

      java -jar cdata.jdbc.sql.jar

      Fill in the connection properties and copy the connection string to the clipboard.

      Microsoft SQL Server への接続

      Microsoft SQL Server への接続には以下を入力します:

      • Server: SQL Server が稼働するサーバー名。
      • User: SQL Server に接続するユーザー名。
      • Password: 接続するユーザーのパスワード。
      • Database: SQL Server データベース名。

      Azure SQL Server およびAzure Data Warehouse への接続

      Azure SQL Server およびAzure Data Warehouse には以下の接続プロパティを入力して接続します:

      • Server: Azure 上のサーバー。Azure ポータルの「SQL databases」(もしくは「SQL data warehouses」)-> データベースを選択 -> 「Overview」-> 「Server name」で確認が可能です。
      • User: Azure に認証するユーザー名。
      • Password: 認証するユーザーのパスワード。
      • Database: Azure ポータルでSQL databases (or SQL warehouses) ページに表示されるデータベース名。
  6. Click the "Test connection" button to confirm the configuration and click Save.

View SQL Server Data in the VirtualPort Administrator Tool

After creating the data source, you can create a base view of SQL Server data for use in the Denodo Platform.

  1. Click the "Create base view" button in the newly created VirtualPort (admin.SQL).
  2. Expand the object tree and select the objects (tables) you wish to import.
  3. Click the "Create selected" button to create views of the SQL Server data.
    Optional: Click "Create associations from foreign keys" to define relationships between the objects.
  4. With the view(s) created, navigate to a table (cdata_sql_orders) in the Server Explorer and double-click the selected table.
  5. In the new tab, click "Execution panel" to open a query panel.
  6. Customize the query in the "Execute" tab or use the default:
    SELECT * FROM cdata_sql_orders CONTEXT ('i18n'='us_est', 'cache_wait_for_load'='true')
    
  7. Click Execute to view the data.

With the base view created, you can now work with live SQL Server data like you would any other data source in Denodo Platform, for example, querying SQL Server in the Denodo Data Catalog.
