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();

Also please check this out, it will give you better solution
