Non-deterministic functions and row-based binary logging (MySQL) Newbie questions. I'm working on a MySQL project that will use only row-level binary logging. There will be no replication. Since logging is row-level, does it even matter if a function is deterministic? From the manual, my understanding is that it does not.

Added 6/9/20: 

I've added an example which I think would be non-deterministic; please tell me if I'm wrong. The result will always be the same for a given state of the data, returning the highest date value in a set of rows, but would not always return the same value for the same input of a given patient id, since that changes over time. Is that right? 

CREATE FUNCTION `last_enc_date`(patient INT) RETURNS date
BEGIN
# Returns the date of the most recent encounter (of any kind) for patient
DECLARE lastvisit DATE;
SELECT MAX(DATE)
    INTO lastvisit 
    FROM encounters 
    WHERE personid = patient;
RETURN lastvisit;
END
Your understanding is correct. RBR is safe even with non-deterministic functions.
