RQL: a view written as a sentence — What it is
Every saved view is already a query: which table, which records, what order. RQL writes that query down:
Invoices
where Status is not Paid and Due in last 30 days
sort by Due asc
Same view, same rows, same engine — this is the view you already built, printed as words. Most people will never need it. It earns its place when you want to see exactly what a view does, send a colleague the precise set you mean, or make an edit that is quicker to type than to click.
