Mysqli加入意想不到的“;”

Question

即将发生意外错误＆＃34;;＆＃34;在这个代码上。不知道问题出在哪里：（

$getProducts = $mysqli->query("SELECT 
               orders.id AS id,
               orders_items.qty AS qty,
               shopping_products.title AS title
               FROM orders 
               JOIN orders_items ON orders_items.ordersID = orders.id
               JOIN shopping_products ON shopping_products.id = orders_items.shopping_productsID
               WHERE orders.authorID = ".$userID.""
);
