Syntax error when doing an update to modify multiple fields using mysql

Can I modify the mysql syntax SET more of a sample script:

UPDATE login SET id='21' AND ip='789' WHERE nama='ariel'

Please corrected if I am wrong.

And should be ,

UPDATE login SET id='21', ip='789' WHERE nama='ariel'

I don't think you should use AND like that. Instead I think it should be something more like a list like this:

UPDATE login SET id='21',ip='789' WHERE nama='ariel'

AND is typically used as part of a WHERE clause, not in the list of fields to be updated.
