我有下面的存儲過程進行預留。我沒有做前端插入值，所以我使用execute從SQL Server菜單存儲過程來插入到數據庫中，但它給我的subquery returned more than 1 value and 1 row affected消息子查詢返回的值超過1。當子查詢跟在=，..或子查詢用作表達式時，這是不允許的。

子查詢'（SELECT [ reservationno ] FROM roombookingdetails）''可能會返回多於1行，應該用'MAX'這樣的集合操作替代，就像你在其他子查詢中使用的那樣 –
好的將使用那個 – saurabh64
你必須使用'where子句'，'Top操作符'，當存在此類問題或多於1條記錄時，子查詢中的「Min，Max，Avg」 –
