mysql insert command with a where clause

Question

im trying to insert data into a particular row in the database, but i mysql is saying this is an error:

Answer 1

UPDATE user 
   SET rep = '5', course = 'computer science' 
 WHERE user = '2'

Link to docs.

Answer 2

You might want to UPDATE instead,

UPDATE user set rep='5', course='computer science' WHERE user='2'

Answer 3

INSERT statement should not come with WHERE clause.
