Do UX designers need to know SQL?

As a curious individual delving into the world of technology and design, I've often wondered about the intersection of user experience design and data manipulation. Specifically, I'm intrigued by the question of whether UX designers truly need to have a grasp on SQL. Is SQL proficiency a must-have skill for UX designers, or is it more of a nice-to-have? Could you elaborate on the potential benefits and drawbacks of UX designers knowing SQL, and how it might impact their ability to create seamless and intuitive user interfaces?
