Dear David!

That was a very good idea! I have integrated it! :-)

Priorly I had another idea: I made a DDL to extend the table with "add column if not exists" elements.
But what you suggested is better. Thank you!

Best wishes

So is there any syntax to not fall on missing columns?

No.  I’d probably approach this by generically converting the NEW record to json and working with that.  Non-existent object keys return null when accessed.
