Q:

How to extract data from an already existing database with genexus?

I am trying to create a model on genexus that gets data from a determined table from a server to create a File.
I have tried doing it while creating a new knowledge base but I didn't know how I can get the data I need or how I can connect the existing tables to my knowledge base.

A:

See this 2 links from GeneXus documentation:

https://wiki.genexus.com/commwiki/servlet/wiki?2414,Reverse%20Engineering%20Process
https://wiki.genexus.com/commwiki/servlet/wiki?6627,Database+Reverse+Engineering+Wizard,

Best Regards.
