«… I did this before...»
Any example available for free? No kidding. Best regards, Karl
BTW, I wonder why someone jumps to the conclusion to build an SQLish language. Isn’t SQL bad enough? The world mapped to index cards 🤪

Excuse my ignorance, but is there a standard for queries searching in JSON like nested structures?

Abstract Syntax Tree. That's the structure parsers usually return (but they don't have to, see e.g. my Marpa Enhanced Calculator where the parser directly calculates the expressions without actually building the tree).
map{substr$_->[0],$_->[1]||0,1}[\*||{},3],[[]],[ref qr-1,-,-1],[{}],[sub{}^*ARGV,3]

Thanks for that, although it's kind ot taken the question off on a tangent.
It's not a database language or directly related to SQL. That was just an example.
