I’m trying to use n8n and I see that typical use flows are rather copy/paste style of things.
I’m curious to learn how can I find rows with empty values. Currently, n8n asks me to have something in this field so it’s impossible to do such a query.
A second question is about making unique ids. Normally I just take time stamp and add a random number at the end. How to create a random function here? how to connect it with timestamp?
