SFTP JDBC Driver

An easy-to-use database-like interface for Java based applications and reporting tools access to remote files and directories.



Integrate SFTP data with standard components and data source configuration wizards in Talend Open Studio.

This article shows how you can easily integrate the CData JDBC driver for SFTP into your workflow in Talend. This article uses the CData JDBC Driver for SFTP to transfer SFTP data in a job flow in Talend.

Connect to SFTP in Talend as a JDBC Data Source

You can follow the procedure below to establish a JDBC connection to SFTP:

  1. Add a new database connection to SFTP data: To add a new connection, expand the Metadata node, right-click the Db Connections node, and then click Create Connection.
  2. In the resulting wizard, enter a name for the connection.
  3. On the next page, select Generic JDBC from the DB Type menu and enter the JDBC URL.

    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.

    Built-in Connection String Designer

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

    java -jar cdata.jdbc.sftp.jar

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

    A typical JDBC URL is below:

    jdbc:sftp:RemoteHost=MyFTPServer;
  4. Enter the path to the cdata.jdbc.sftp.jar file, located in the lib subfolder of the installation directory.
  5. Right-click the connection and then click Retrieve Schema.
  6. Click Next with the default options to select the tables you want to import.
  7. Finish the wizard with the default options.

Output the MyDirectory Table to a Flat File

You can follow the procedure below to transfer the MyDirectory table to a flat file output component:

  1. In the Table Schemas node, drag the tables to the workspace.
  2. In the dialog that is displayed, select the tJDBCInput component.
  3. Next, drag a tFileOutputDelimited component from the Business Intelligence tab of the Palette into the workspace.
  4. Right-click the MyDirectory tJDBCInput component and drag a vector to the output file.

Run the project to transfer the data.
