UPDATE Query without WHERE Clause

Question

I know it sounds to be a stupid question but i was wondering if the update query can be used without a where clause. And if so in what conditions.<

Answer 1

So, I think when you want to update the whole field for some kind of reasons like updating the status of users enrollment to free for all users.

UPDATE users SET status = "free";

Answer 2

if you don't use the WHERE clause all the records on the table will be affected
