The WHERE clause checks the condition and the changes mentioned by the DELETE or UPDATE command will be done if the condition is true. There are also other clauses like HAVING, IN which will have range either inclusive or exclusive.
It is also noted that in MySQL, there is a method called WorkBench which enables safe mode and doesn’t execute statements without the WHERE clause.
