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

That will give you the same result. However, LIKE allows wildcards, for example...

SELECT * FROM users WHERE username LIKE 'davy%'

The only syntax problem was double quotes instead of single quotes
