array( 'entry_id' => $entryid, 'slug' => 'registration'),

$wpdb->update(   'wp_cf_form_entry_values',    array(      'value' => $regcode  //entering data in value field   ),    array( 'entry_id' => $entryid, 'slug' => 'registration'), //two  clause array(      '%s'     //specifying type of value entering in table   ),  array('%d', '%s' ) //specifying type of value using in cluase
