How to apply filter on JSON format database in CodeIgniter

Question

I have a database of a table named ' literature ' in this table there is only one column " item_details " having data in JSON format as given below:-

{
    "book":[
            {
                "language":"English",
                "author":["Y.Nikhilendra","Paresh Khairnar","Madhabendra Rout"]
            },
            {
                "language":"English",
                "author":["Sai Seetharam Nomula"]
            }
        ],
    "diary":[
            {
                "language":"Hindi",
                "author":["Partha Banerjee"]
            },
            {
                "laguage":"English",
                "author":["Gaurav Pandey"]
            }
        ]
}

I want to apply filter option according to languages in CodeIgniter . in the controller

public function view()
{
    $response = $this->view_model->viewModel( $language);       
}

Model:-

public function viewModel($language)
{
    $this->db->select(*);
    $this->db->from('literature');
    $this->db->where
    //What would be structure of where clause?
}
