INSERT Batch, and if duplicate key Update in codeigniter

问题

Is there any way of performing in batch Insert query and if the key already exists, UPDATE that row in codeigniter? I have gone through the documentation and found only insert_batch and update_batch. But how to update the row with duplicate key in active records? And what happens if one row fails to be inserted or updated in batch_insert? All insertion fails or only that row?

You will have to go with little custom query by adding "ON DUPLICATE" statement

$sql = $this->db->insert_string('YourTable', $data) . ' ON DUPLICATE KEY UPDATE duplicate=duplicate+1';
$this->db->query($sql);
$id = $this->db->insert_id();
