How would I use ON DUPLICATE KEY UPDATE in my CodeIgniter model?

Question

I have a CodeIgniter/PHP Model and I want to insert some data into the database.

However, I have this set in my \'raw\' SQL query:

ON DUPLICATE KEY U         


        

Answer 1

You can add the "ON DUPLICATE" statement without modifying any core files.

$sql = $this->db->insert_string('table', $data) . ' ON DUPLICATE KEY UPDATE duplicate=LAST_INSERT_ID(duplicate)';
$this->db->query($sql);
$id = $this->db->insert_id();

I hope it's gonna help someone.
