Better late than never...
After VWSql was no longer sold, and its licens was compleatly to my old computer, I did some mysql (now inside MariaDB) script (after 5.x) when triggers ("on insert/update") were supported. I still use that to import and manually update through a daily csv file. I did modify the database from VWSql with data since VWS csv, dbase.csv, supported so many other weather stations besides Davis's. It takes it from the VWSql format and checks data and insert everything to my new, but similar database. The new database has for f ex RecDate converted to MySQL/MariaDB datetime, and some additional indexes to facilitate my own statistical purposes.
I'd be happy to send anyone the procedures for making the new database, and the convert from VWSql-database. And maybe I even have the import from old VWSql database to the new one directly.
But it is 'No Questions Asked', I am in the middle of moving and having orthopedic surgery this spring and summer - and after the move I will no longer use VWS at all.
