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

Below is a code snippet I use everytime for update on duplicates:

$sql = "insert into  table_name (id, name) values(".$id.",'".$name."') on duplicate key update id=".$id.",name='".$name."'";
//Executing queries
$result = $this->db->query($sql, array($id, $name)); 

Note: column id must be primary or unique
