The program below will copy the data down to a text or binary file and will then read that file to reload the table again. Obviously there are a few caveats;
- Table structures between the two systems must be completely identical.
- Default parameters for things like date formats need to be identical between the two systems.
This is an improvement of a previous program I wrote as this one will handle GUIDs and text in foreign languages as well provided you use the binary format.
It's possible to limit the data that gets downloaded by using the Data selection button after you've selected the table and field names. This will dynamically build a new selection screen where you can select values to limit your data selection. You can also automatically split the file at a predefined record count if you're going to be working with really huge files.
When you're uploading you can decide if you want to skip existing records with the same key fields or simply overwrite them.
