Build Data Flows from SFTP to SQL Server using SSIS

Using SQL Server as a backup for critical business data provides an essential safety net against loss. Backing up data to SQL Server enables business users to more easily connect that data with features like reporting, analytics, and more.

This example demonstrates how to use the CData SSIS Tasks for SFTP inside of a SQL Server SSIS workflow to transfer SFTP data into a Microsoft SQL Server database.

Add the Components

To get started, add a new SFTP source and SQL Server ADO.NET destination to a new data flow task.

Create a New Connection Manager

Follow the steps below to save SFTP connection properties in a connection manager.

1. In the Connection Manager window, right-click and then click New Connection. The Add SSIS Connection Manager dialog is displayed.
2. In the Connection Manager type menu, select SFTP. The CData SFTP Connection Manager is displayed.
3. Configure connection properties.

   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. 👁 Configuring a connection (Salesforce is shown).
   

Configure the SFTP Source

Follow the steps below to specify the query to be used to extract SFTP data.

1. Double-click the SFTP source to open the source component editor.
2. In the Connection Manager menu, select the connection manager previously created.
3. Specify the query to use for the data extraction. For example:

   SELECT Filesize, Filename FROM MyDirectory WHERE FilePath = /documents/doc.txt
   

   👁 The SQL query to retrieve records. (Salesforce is shown.)
   
4. Close the SFTP Source control and connect it to the ADO.NET Destination.

Configure the SQL Server Destination

Follow the steps below to specify the SQL server table to load the SFTP data into.

1. Open the ADO.NET Destination and add a New Connection. Enter your server and database information here.
2. In the Data access mode menu, select "table or view".
3. In the Table Or View menu, select the table or view to populate.
4. Configure any properties you wish to on the Mappings screen. 👁 The mappings from the SSIS source component to SQL Server. (Salesforce is shown.)
   

Run the Project

You can now run the project. After the SSIS Task has finished executing, your database will be populated with SFTP data.
