How to make an endpoint with multiple OPTIONAL query params in flask restful with SQL?

Question

I’m having a hard time figuring out how to make a query to the DB with multiple optional query params. That’s because they’re may not be all in the query, so i don’t know how to apply it to a flask endpoint like the following

class auctions(Resource):
    
    def get(self):
        breed = request.args.get('breed', type=str)
        not_started = request.args.get('notstarted', type=str)
        finished = request.args.get('finished', type=str)
        if breed:
            query = breed_query_param(breed)
        else:
            query = "select * from auctions"
        data = httpUtils.execNonQuery(query)
        return data

The httpUtils is going to query but i dont know how to make multiple optional wueerys and pass it to the SQL script

def breed_query_param(breed):
    query = f"""
            select auctions.id,
                auctions.started_price,
                auctions.final_price,
                auctions.created_at,
                auctions.start_at,
                auctions.end_at,
                auctions.livestock_resume_id,
                auctions.user_creator_id,
                auctions.winner_user_id,
                auctions.namee,
                auctions.description,
                livestock_breed.breed
            from auctions, livestock_breed
            where breed = '{breed}'
            """
    return query
