It is very difficult moving from Alteryx functions to SQL In-Database as a business user, I need to learn a whole new language.
In the short term Alteryx should provide a simple function reference, as similar as possible to the Formula tool, for building formula in the in-database tools.
Longer term I'd like there to be a parser from Alteryx Formulae to SQL so I can just write in my favourite Alteryx formula (or a subset thereof) and Alteryx handles the conversion to SQL.
