Import Real-Time FTP Data via ODBC in ColdFusion to Build Applications

Use CData ODBC drivers to import and use FTP data in ColdFusion.

Adobe ColdFusion is a web and mobile application development platform. It uses its own scripting language, ColdFusion Markup Language (CFML), to create data-driven websites as well as generate remote services, such as REST. When ColdFusion is paired with the CData ODBC Driver for FTP, you can link your ColdFusion web and mobile applications to operational FTP data. This allows for your applications to be more robust and complete. This article details how to use the ODBC driver to create a table populated with FTP data from within a ColdFusion markup file.

To follow along with this tutorial, you need to install the CData ODBC Driver for FTP and Adobe ColdFusion.

Configuring the Connection

If you have not already, first specify connection properties in an ODBC DSN (Data Source Name). This is the last step of the driver installation process. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.

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.

Adding a Data Source and Creating a Table

After creating a DSN, follow the steps below to add a new data source, test our connection to it, create a ColdFusion markup file, and, finally, import FTP Data and display it in a table in ColdFusion:

From the ColdFusion administrator interface, choose Data & Services. 👁 Selecting Data & Services
Here, click "Add New Data Source". The data source name can be any name, provided it conforms to the ColdFusion variable naming conventions. For our ODBC driver, choose "ODBC Socket", then click the "Add" button. 👁 Adding Data Source Name
From the ODBC DSN Dropdown menu select CData FTP Sys. Under the Advanced Settings section, leave the Connection String blank. Note that any properties specified in this input field will override the ones specified in the DSN Configuration. 👁 Populating driver properties
Now, test the connection by pressing the check mark to the left of the CDataFTPODBC data source you just created. When the data source reports an "OK" status, it is ready for use. 👁 Testing the connection

Next, create a new ColdFusion Markup file (.cfm) and place it in the wwwroot directory ("C:\ColdFusion2021\cfusion\wwwroot") for ColdFusion.

The following code queries the data source:

 
 <cfquery name="FTPQuery" dataSource="CDataFTPODBC"> 
 SELECT * FROM MyDirectory 
 </cfquery>

And a CFTable can be used to quickly output the table in HTML:

 
 <cftable 
 query = "FTPQuery" 
 border = "1" 
 colHeaders 
 colSpacing = "2" 
 headerLines = "2" 
 HTMLTable 
 maxRows = "500" 
 startRow = "1"> 

 <cfcol header="<b>Filesize</b>" align="Left" width=2 text="Filesize"/> 

 <cfcol header="<b>Filename</b>" align="Left" width=15 text="Filename"/> 

 ...

 </cftable>

Full code, including the HTML portion is available below:

 
 <html> 
 <head><title>CData Software | FTP MyDirectory Table Demo </title></head> 
 <body> 
 <cfoutput>#ucase("FTP MyDirectory Table Demo")#</cfoutput> 
 <cfquery name="FTPQuery" dataSource="CDataFTPODBC"> 

 SELECT * FROM MyDirectory 

 </cfquery> 
 <cftable 
 query = "FTPQuery" 
 border = "1" 
 colHeaders 
 colSpacing = "2" 
 headerLines = "2" 
 HTMLTable 
 maxRows = "500" 
 startRow = "1"> 
 <cfcol header="<b>Filesize</b>" align="Left" width=2 text="Filesize"/> 

 <cfcol header="<b>Filename</b>" align="Left" width=15 text="Filename"/> 

 ...

 </cftable> 
 </body> 

 </html>

Finally, run the code in a browser. It produces a table populated with FTP data! 👁 Running the code

As a note, the CData ODBC Drivers also support parameterized queries using the cfqueryparam element. For example:

SELECT * FROM Account WHERE name =
