Connect to SFTP Data in DBeaver

The CData ODBC Driver for SFTP enables access to live data from SFTP under the ODBC standard, allowing you work with SFTP data in a wide variety of BI, reporting, and ETL tools and directly, using familiar SQL queries. This article shows how to manage SFTP data with visual tools in DBeaver like the query browser.

The CData ODBC drivers offer unmatched performance for interacting with live SFTP data in DBeaver due to optimized data processing built into the driver. When you issue complex SQL queries from DBeaver to SFTP, the driver pushes supported SQL operations, like filters and aggregations, directly to SFTP and utilizes the embedded SQL engine to process unsupported operations (often SQL functions and JOIN operations) client-side. With built-in dynamic metadata querying, you can manage and analyze SFTP data.

Connect to SFTP

If you have not already done so, provide values for the required connection properties in the data source name (DSN). You can configure the DSN using the Microsoft ODBC Data Source Administrator. 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.

SFTP can be used to transfer files to and from SFTP servers using the SFTP Protocol. To connect, specify the RemoteHost;. service uses the User and Password and public key authentication (SSHClientCert). Choose an SSHAuthMode and specify connection values based on your selection.

Set the following connection properties to control the relational view of the file system:

• RemotePath: Set this to the current working directory.
• TableDepth: Set this to control the depth of subfolders to report as views.
• FileRetrievalDepth: Set this to retrieve files recursively and list them in the Root table.

Stored Procedures are available to download files, upload files, and send protocol commands. See gdatamodel for more on using SQL to interact with the server.

Finally, set the "Map To WVarchar connection property to False in the DSN Configuration window for the driver. This configuration will allow string types to be mapped to SQL_VARCHAR and prevent SQL_WVARCHAR types from being displayed as NULL.

Connecting to the SFTP ODBC Data Source in DBeaver

1. Open the DBeaver application and in the Database menu, select the New Database Connection option. 👁 Creating a new Database Connection
   
2. In the 'Connect to a database' window, select ODBC and click Next. 👁 Creating a new Database Connection
   
3. In the Database/Schema field, enter the DSN name (CData SFTP Source by default). It will be automatically added to the JDBC URL as well.
4. Click the Test Connection button. You should receive a 'Connected' message after DBeaver has detected the DSN, along with details about the driver if the connection is successful. 👁 Successfully tested connection
   

Query SFTP Data

You can now query information from the tables exposed by the data source connection. You can expand the database structure in order to view all the tables. You can retrieve the table's data by right-clicking on a table name and selecting View data. The data will then be available in the Data tab.
