Report of employees present in the company today

Hello everyone, I have to say that factorial has very good development support.
I have some rudiments of programming and I need to compose a query that generates a report of the employees actually present in the company in the current day.
I generated a complete table with SELECT * from EMPLOYEES but I couldn't find any field that could help me. I think I'm looking in the wrong table. Can someone tell me the parameter to use? I guess it must be something similar to presence. Thank you all.
