Answer 1

A simple one would be

INSERT INTO table1 (col1, col2, col3)
SELECT col1, col2, col3
FROM   table2

In CI use query()

$this->db->query("INSERT INTO table1 (col1, col2, col3)
    SELECT col1, col2, col3
    FROM   table2");

Here is the other way

$data = $this->db->select('col1, col2, col3')->get('table2');
if($data->num_rows())
{
    $insert = $this->db->insert('table1', $data->result_array());
}
