Choosing the Best Method to Connect SFTP to SQL Server: 5 Options Explained

Integrating SQL Server with other systems or applications like SFTP is essential for modern businesses to leverage their data effectively as it centralizes data management and streamlines operations.

A developer, solution architect, or business user looking to connect their organization's application to SQL Server for improved data analysis or streamlined processes should consider these key questions before selecting a solution:

• Can I build this integration myself?
• Does the application data need to be written to SQL Server?
• Will a linked server be used to virtually access SQL Server?
• Is this part of a broader data analysis platform?
• Will it serve for data integration or business automation?

CData Software's product portfolio addresses all these concerns, offering robust integration solutions to SQL Server that simplify the process.

In this article, we explore five methods provided by CData for connecting to and utilizing SFTP data from SQL Server, while examining how each method suits specific business use cases.

For data integration and business automation: No-code integration between SFTP and SQL Server with CData Arc

CData Arc is a server application designed to automate data integration across CData products. It facilitates API integration with SaaS, as well as file and database integration, using no-code and low-code approaches. This product aims to simplify the often-complex process of B2B integration, whether on the cloud or on-premise.

CData Arc comes with CData connectors, enabling seamless use of CData Drivers, which offer the industry's largest number of connection destinations. This allows you to support a wide range of data sources beyond SFTP, all with a consistent user experience.

All editions of CData Arc feature a robust integration engine and a flexible licensing system tailored to the scale of use. This makes it ideal for first-time users of data integration tools or those seeking a low-code solution that fits their budget. Whether you need integration with SaaS, on-premise systems, or file integration, CData Arc can handle it all.

The integration logic you wish to implement can be configured using the CData Arc flow designer.

If you're good with SQL Server: Access SFTP data as a linked server with SQL Gateway

SQL Server offers an integration feature called linked servers, which allows you to access other databases directly from SQL Server. By utilizing the CData SQL Gateway with the CData ODBC Driver for SFTP, you can treat SFTP data as a linked server within SQL Server. While the data isn't physically stored in SQL Server, you can query SFTP data using SQL through the SQL Server interface.

After configuring the standard ODBC Driver for the SFTP DSN, launch SQL Gateway and set up the SFTP DSN as an SQL Server service. By registering this service as a linked server in SSMS, you can query SFTP data directly in SQL, making it ideal for referencing SFTP data across multiple .NET client applications and performing JOINs with SQL Server data.

For those familiar with SQL Server linked servers, this is the easiest method to use. It offers the advantage of querying real-time SFTP data and allows bi-directional linking, including writing, directly from SQL Server.

However, the only drawback is that the SQL Gateway must be hosted and managed on a server, which can incur high server hosting costs.

For SSIS users: Import SFTP data into SQL Server with SSIS

Many SQL Server users rely on SSIS (SQL Server Integration Services) for data integration and workflow automation. CData provides an SSIS Component for SFTP, enabling seamless connectivity between SSIS and SFTP.

If you're an SSIS user, you can easily set up an import flow to SQL Server using the SFTP Component. Priced similarly to the driver, it offers a cost-effective solution.

For users of ETL/EAI tools other than SSIS, CData Drivers provide a simple way to connect data. They are compatible with various ETL tools such as ASTERIA Warp, DataSpider, Informatica, and Waha! Transformer, RACCOON, Talend, and more. SFTP and ETL integration articles listed here (including the SFTP ETL, Replication & DWH Connection Guide), offer further guidance.

For ETL tool users, this option is cost-effective and easy to implement. You can integrate SFTP by simply adding the driver to your existing tool.

Integrate into your data analytics infrastructure: Replicate SFTP to SQL Server with CData Sync

If you're looking to connect SFTP and SQL Server without coding, integrate data and use SQL Server as an analytical platform, we recommend CData Sync. This server-based ETL/ELT tool allows you to easily set up a replication job in just three steps after installation. You can also schedule tasks and customize replication settings, all through an intuitive GUI.
