Upsize VFP Free Tables to SQL Server

The VFPX Upsizing Wizard allows you to upsize the tables in a database container to a SQL Server database. It can be used visually by running or programmatically; see TestEngine.prg that comes with the Upsizing Wizard for an example.

One thing the Upsizing Wizard doesn't do is support free tables. The new Upsizer utility gives the Upsizing Wizard the ability to do that. I've used it on decent sized data sets (more than 100 tables with 10 GB of data total) and it works very well. One thing I like is that I can run it over and over to upsize to the same database; that allows me to refresh the SQL Server database with changes in the VFP data while we work on upsizing a VFP application.

Updated Upsizing Wizard

I released an update for the Upsizing Wizard that fixes a few bugs and adds some new features. Some of these were suggested by Rick Borup in his Switching to SQL Server session at Virtual Fox Fest 2022 (October), including:

  • Optionally creating default values for all columns so fields that don't allow nulls and aren't listed in an INSERT statement don't prevent the statement from executing.
  • Optionally exporting table and field comments to the MS_Description extended property.
  • Using Varchar(max) rather than Text as the default mapping for Memo.

See the 2022.12.27 section of the Releases section of the Upsizing Wizard VFPX repository for details on all changes.

You can install the new version by cloning the repository, downloading the files from the repository, or using Thor Check for Updates.

And stay tuned: later this week, I'm going to release a new tool that extends the Upsizing Wizard to support free tables and uses SQL Bulk Copy for even better upsizing performance.
