A Database Error Occurred
You must use the "set" method to update an entry.

Thanks in Advance

The code you posted is not related to the error message you got.
Please post your model-code where your db update code runs.

[eluser]praveena[/eluser]
$upload=array(
'filename'=>$this->input->post('filename'),
'filepath'=>$this->input->post('filepath'));
$insert= $this->db->insert('data',$upload);
return $insert;

This is my model code

That code looks ok. I think the error is not comming from there.
The error message is talking about "updating" while
the code you posted is about INSERT. Do you have other
sql statements in your controller? Can you provide more
code? Please use CODE-tags when posting code - it's far
more readable!
