So there is a lot of funtions in Codeigniter model. So can i call it a PL SQL because it is programmable and has lot of functions in it. below is small snippet syntax of a model.
class Assign_books_model extends CI_Model {
public function findstudents1($post_data) {
//some group of db query's run here
}
public function findstudents2($post_data){
//some other group of db query's run here
}
}
You could only create the procedure(PLSQL) on the server(Oracle/mysql). And can be called with
$this->db->call_function('plsql');
