Back in 4Dv11 days, I was asked to connect to a SQL database with 4D. With 4D, I was able to connect to a test copy of the SQL system. I found and extracted the list of the SQL tables. And, for each table, I extracted the field map. I then wrote 4D code to do sample data extracts for each table - actually wrote 4D code to generate 4D code for the extracts. Took 3-4 days.
Figured out what the client actually need, etc. The system is still running. The code is probably around here somewhere - I’m like a packrat - I never throw code away. > On Oct 8, 2019, at 10:04 PM, Chip Scheide via 4D_Tech <4d_tech@lists.4d.com> > wrote: > > My use of SQL is very limited... > I have been asked to try to gather data from 4 separate commercial databases > (assumed to be running some SQL compliant system of unknown origin - i.e. > mysql, ms sql server etc) and try to coordinate the data and produce a report > summarizing the combined data. > > so..
