我已經將你的想法應用於我的真實世界，並且它在存儲過程中完美工作。感謝那！ 但是我的SQL客戶端不支持存儲過程...對我感到羞恥！
所以我決定創建一個表函數（用pamareters）來調用這個SQL代碼。我有沒有找到方式來使用你的中間編號表（在我的使用中稱爲事件）... ... 我有以下錯誤行「; WITH事件AS」： ==>包括選擇語句如果函數不能將數據返回給客戶端。
下面是功能代碼我做：

你會一直爲它神奇的解決方案？
再次感謝您的幫助！ François
太棒了！感謝這個答案！你有解決方案只有一個SELECT和ROW_NUMBER（）使用？我不確定我的最終SQL客戶端是否會允許這樣的請求......無論如何，聽起來不錯！ :) – Francois 2014-10-08 12:46:08
