Worked example using the FTP Task

We will run through an example using an FTP
Task to receive the readme.txt file from the developr folder
of Microsoft.com. The FTP address from where the file will be downloaded is ftp.microsoft.com

1.    Create a new SQL
Server Integration Services Project and rename the default package FTPTaskExample.dtsx

2.    Double click FTPTaskExample.dtsx
package to open it up in Design mode.

3.    Add variables named
FTPDestinationPath and FTPSourcePath; you can open up the Variables window by
right clicking within the control flow design window and by choosing the
Variables option from the drop down list as shown in the snippet below.

4.    Once the variables
window opens up, click on the Add Variable button and provide the details for
the variable as shown in the snippet below.

5.    Create a new folder
named FTPDestination within the C Drive. The readme.txt file which will
be received using the FTP Task will be saved in this folder location.

6.    Right click within
the Connection Managers window and select New Connections… from the
popup window. This will open up the Add SSIS Connection Manager window,
select FTP and click Add…   to configure the FTP Connection Manager.

7.    Within the FTP
Connection Manager Editor window, under Server Setting set the Server Name to  ftp.microsoft.com and set  the Server
Port value to 21 which is the default port for most FTP sites. Under
Credentials set the User Name value to anonymous and leave the password field   blank.
Under Options make sure to you have selected Use Passive Mode which allows you
to initiate the data connection to the FTP servers. If the Use Passive Mode
checkbox is unchecked then the FTP connection is in Active Mode and  the server
initiates the data connection. Click   Test Connection   to verify the FTP
connection. Click OK to save the change in FTP connection manager.

8.       Drag and drop FTP
Task from the toolbox to the Control Flow window and rename it   “Download a
File Using FTP Task”, then double click the FTP Task to open up the editor
window as shown in the snippet below.

Within the FTP Task
Editor, click on General tab in the left panel and then from the right side
panel under Connection choose FTPConnection value as “FTP Connection Manager”.
