WordPress SQL ( Table Inserts )

Just Selects all rows

global $wpdb;

$table_name = "yolo_molo";

$user_id       = $args['user_id'];

$sql = "SELECT * FROM " .$table_name." WHERE pilot_id = $user_id";

$sql = $wpdb->prepare( "SELECT * FROM " .$table_name." WHERE pilot_id = %d", $user_id );

$all_results = $wpdb->get_results($sql, ARRAY_A);

var_dump($all_results);

$wpdb->update(
$table_name,
array(
'icon'         => $icon,
'name'         => $track_name,

'sponsor_link' => $sponsor_link

array( 'pilot_id' => $user_id ),

$column_name_values['icon']     = $icon;
$column_name_values['name']     = $track_name;
$column_name_values['content']  = $track_content;

$column_name_wheres['pilot_id']   =  $user_id;
