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 gets you to work with wild card operators, you may use it in your case for like 'davyjon%' to get all the results starting with davyjon, and to get the exact you may place 'davyjones' and you may also use = in this case
