Hi Chip, The answer is yes to your three questions, but access to the table/fields schema will need to be granted to the user. Also, “automagically’ creating a matching 4D structure will require you write code, so it’s not very ‘magic’. ;)
Extracting data should be straightforward. It’s just a matter of writing queries (SELECT) and putting the returned arrays into records or write to text files. It’s possible to SYNCHRONIZE 4D tables with SQL tables, but I have no experience with that feature. Is the goal to generate the reports in 4D? Or in SQL?
