Hello.
How in "Codeigniter style" make these query's

Code:

mysql_query("UPDATE mailng_list SET name = '$name', surname = '$surname'
WHERE mail_id = '$mail_id' AND userId = '$userId' ");

mysql_query("UPDATE mailng_list_entry SET email = '$email'
WHERE mail_id = '$mail_id' ");

i know userId and mail_id

More information:

mailng_list
===========
mail_id
userId
name
surname


mailng_list_entry
=================
mail_id
email

relationship: mailng_list.mail_id -> mailng_list_entry.mail_id (LEFT JOIN)

Any help please.
