Question

我有一个出价表，id，sellerId，buyerId，notifId amount .... 如果我的id（sellerId）存在且notifId不存在我不想返回任何行所以我的sellerId是50001，我已经对notifId 1260出价，没有返回结果，那很好我可以做到这一点，但它将返回卖方1442的行，同样的报告。如果我的id存在于具有相同notifid的任何行，我不想返回任何内容希望像泥一样清楚。

 Application.Run("Test",
            Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing,
            Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing,
            Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing,
            Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing,
            Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing,
            Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing);

而不是EXISTS （ SELECT null FROM notification_hide nh WHERE nh.notifId = n.notifId和nh.sellerId = sellerId ））

mysql如果select是我的id，则不返回任何行
