We recently had a client who needed to query data from a legacy system built on FoxPro. What is FoxPro you ask? Fox Software was a company Microsoft purchased back in the early 90s, and they developed a system that accelerated the development of business / database applications. You can think of FoxPro as a technology in between Access and VB. It is more complex and powerful than Microsoft Access, but requires less code to write than a VB.net application.
The problem now is that Microsoft has stopped the development of FoxPro for the last 10-15 years, and the supporting tools have been slowly decaying. There is no longer an ODBC drive for FoxPro. So if you want to query a FoxPro database, you’ll need to use the OLE DB drivers. The latest drivers can be downloaded here: Microsoft OLE DB Provider for Visual FoxPro 9.0 SP2
And for any of the latest Microsoft downloads for FoxPro, go to: https://msdn.microsoft.com/en-us/library/mt490121
So what if you want to import data into SQL Server using the Data Import Wizard, or add the FoxPro database as a linked server? Well, one issue you might run into is that the FoxPro OLEDB drivers are only 32 bit – sorry no 64 bit versions. So if you’re running a 64 bit version of SQL Server, then you won’t be able to do it. So what can you do? Install a 32 bit version of Sql Server. As of this article, SQL Server 2016 has no support for 32 bit, so you need to download an earlier version. SQL Server 2014 has a 32 bit version.
So how are we going to get data out of FoxPro? The basic flow is going to look like this:
FoxPro Db -> Linked Server -> 32 bit Sql Server Instance -> Composable -> 64 bit SQL Server
We’ll link the FoxPro db to the 32 bit version which will allow us to write SQL queries against the FoxPro db. We’ll then write a syncing dataflow in Composable to query the 32 bit SQL Server instance and insert the records in another SQL Server instance.
First, create a Linked Server in SQL Server:
- Download and install an x86 version of SQL Server 2014.
- Download and install the OLE DB FoxPro drivers.
- Add a FoxPro Linked Server to the x86 SQL Server instance
Set up the Linked Server as follows:

- Server Objects -> Add Linked Server …
- Provider: Microsoft OLE DB Provider for Visual FoxPro
- Product Name: VFPOLEDB
- Data Source: Set the path to the folder containing the FPT and DBF files.
- Note that a file share may cause permission errors, so start out with the local folder that the SQL Server engine users have permission to access.
- Provider String: VFPOLEDB
- In order for the Linked Server to work properly under a 32-bit process and with the necessary permissions, the FoxPro OLE DB Provider needs to be configured with
Allow inprocess
, which will execute the provider within the SQL Server process.- Linked Servers -> Providers -> VFPOLEDB

With the Linked Server configured, you can simply write a query such as:
1 |
select * from [LinkedServerName]…[FoxProTableName] |
Now, all that’s left is to create a DataFlow that runs the above query and inserts data into another SQL Server instance. Note that this DataFlow will transfer the data very efficiently – capable of moving millions of rows in just a few minutes.

Congratulations! You just queried FoxPro data from Composable.
