子查询返回了 1 个以上的值。当子查询跟在 =,.. 或子查询用作表达式时，这是不允许的
Subquery returned more than 1 value. This is not permitted when the subquery follows =,.. or when the subquery is used as an expression
我有以下存储过程来进行预订。我没有完成插入值的前端，所以我使用 sql 服务器菜单中的执行存储过程来插入数据库，但是它给我 subquery returned more than 1 value and 1 row affected 消息

您的以下语句可能 returns 不止一个值。
请检查。
> SELECT [reservationno] FROM roombookingdetails
您已经在插入语句中使用了它。
当存在此类问题或存在超过 1 条记录时，您必须在子查询中使用where clause、Top operator、Min,Max,Avg。
替换第一个插入的(SELECT [reservationno] FROM roombookingdetails)
有了这个
(SELECT Isnull(Max(reservationno) + 1, 1) FROM roombookingguestdetails)
和这个 (SELECT [reservationno] FROM roombookingdetails) 来自第二个插入
用这个(SELECT Isnull(Max(reservationno) + 1, 1) FROM (RoomBookingOccupancy)
