mysql - MySQL RIGHT JOIN 停止使用此 AND 语句

Question

当我有这个时：

SELECT * FROM orders_chosenoptions
RIGHT JOIN orders ON (orders.ID = orders_chosenoptions.order_id)
WHERE orders.deal_id = 982
AND orders.status = 'new'

它给了我 41 行。现在这些行的 orders_chosenoptions.product_id 要么是 110 要么是 111

SELECT * FROM orders_chosenoptions
RIGHT JOIN orders ON (orders.ID = orders_chosenoptions.order_id)
WHERE orders.deal_id = 982
AND orders.status = 'new'
AND (orders_chosenoptions.product_id = 110 OR orders_chosenoptions.product_id = 111)

给我35行？！就像它以某种方式停止了正确的加入？

除了 110 或 110 之外，没有其他行的产品 ID。

尝试这个

SELECT * FROM orders_chosenoptions

  ON orders.ID = orders_chosenoptions.order_id
  and orders.deal_id = 982
  AND orders.status = 'new' 
where orders_chosenoptions.product_id = 110
   OR orders_chosenoptions.product_id = 111

尝试这个：：

SELECT * FROM orders_chosenoptions
RIGHT JOIN orders ON (orders.ID = orders_chosenoptions.order_id)
WHERE orders.deal_id = 982
AND orders.status = 'new' AND
orders_chosenoptions.product_id in (110, 111)
