WordPress wpdb update not working

1. Fatal error: Call to a member function update() on null

   According to the error -$wpdb is undefined.

   My guess is that you’re using this code in a function.
   If this is the case, you should add the following line in order to use this class in your function:

   global $wpdb;
   

   So your code should look like:

   function anon_function($uid) {
    global $wpdb;
   
    $wsquery = array( 'faculty_id' => $uid);
    $tid = array('id'=>1);
    $tname = 'imtd_faculty_in_focus';
    $wpdb->update( $tname, $wsquery , $tid);
   }
