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

Simply done -

    $updt_str = '';
    foreach ($insert_array as $k => $v) {
        $updt_str = $updt_str.' '.$k.' = '.$v.',';
    }
    $updt_str = substr_replace($updt_str,";", -1);
    $this->db->query($this->db->insert_string('table_name', $insert_array).' ON DUPLICATE KEY UPDATE '.$updt_str);

Answer 2

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.
