Connect to FTP Data in HULFT Integrate

HULFT Integrate is a modern data integration platform that provides a drag-and-drop user interface to create cooperation flows, data conversion, and processing so that complex data connections are easier than ever to execute. When paired with the CData JDBC Driver for FTP, HULFT Integrate can work with live FTP data. This article walks through connecting to FTP and moving the data into a CSV file.

With built-in optimized data processing, the CData JDBC Driver offers unmatched performance for interacting with live FTP data. When you issue complex SQL queries to FTP, the driver pushes supported SQL operations, like filters and aggregations, directly to FTP 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 FTP data using native data types.

Enable Access to FTP

To enable access to FTP data from HULFT Integrate projects:

1. Copy the CData JDBC Driver JAR file (and license file if it exists), cdata.jdbc.ftp.jar (and cdata.jdbc.ftp.lic), to the jdbc_adapter subfolder for the Integrate Server
2. Restart the HULFT Integrate Server and launch HULFT Integrate Studio

Build a Project with Access to FTP Data

Once you copy the JAR files, you can create a project with access to FTP data. Start by opening Integrate Studio and creating a new project.

1. Name the project
2. Ensure the "Create script" checkbox is checked
3. Click Next
4. Name the script (e.g.: FTPtoCSV)

Once you create the project, add components to the script to copy FTP data to a CSV file.

Configure an Execute Select SQL Component

Drag an "Execute Select SQL" component from the Tool Palette (Database -> JDBC) into the Script workspace.

1. In the "Required settings" tab for the Destination, click "Add" to create a new connection for FTP. Set the following properties:
   • Name: FTP Connection Settings
   • Driver class name: cdata.jdbc.ftp.FTPDriver
   • URL: jdbc:ftp:RemoteHost=MyFTPServer;
     
     

     Built-in Connection String Designer

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

     java -jar cdata.jdbc.ftp.jar

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

     To connect to FTP or SFTP servers, specify at least RemoteHost and FileProtocol. Specify the port with RemotePort.

     Set User and Password to perform Basic authentication. Set SSHAuthMode to use SSH authentication. See the Getting Started section of the data provider help documentation for more information on authenticating via SSH.

     Set SSLMode and SSLServerCert to secure connections with SSL.

     The data provider lists the tables based on the available folders in your FTP server. 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 folders to list as views.
     • FileRetrievalDepth: Set this to retrieve and list files recursively from the root table.

     Stored Procedures are available to download files, upload files, and send protocol commands. See the Data Model chapter of the FTP data provider documentation for more information.

2. Write your SQL statement. For example:

   SELECT Filesize, Filename FROM MyDirectory

3. Click "Extraction test" to ensure the connection and query are configured properly
4. Click "Execute SQL statement and set output schema"
5. Click "Finish"

Configure a Write CSV File Component

Drag a "Write CSV File" component from the Tool Palette (File -> CSV) onto the workspace.

1. Set a file to write the query results to (e.g. MyDirectory.csv)
2. Set "Input data" to the "Select SQL" component
3. Add columns for each field selected in the SQL query
4. In the "Write settings" tab, check the checkbox to "Insert column names into first row"
5. Click "Finish"

Map FTP Fields to the CSV Columns

Map each column from the "Select" component to the corresponding column for the "CSV" component.

Finish the Script

Drag the "Start" component onto the "Select" component and the "CSV" component onto the "End" component. Build the script and run the script to move FTP data into a CSV file.
