What's the difference between “LIKE” and “=” in SQL?

Question

Is there any difference between:

SELECT * FROM users WHERE username=\"davyjones\"

and

SELECT * FROM users WHERE username LI         


        

Answer 1

Like is pattern matching operator and = is exact matching operator. i.e. where name like W% it means start with W and after that one or more characters and = i.e. where name ='James' this is exact matching
