間隔SQL查詢組

Question

我需要找到如何查詢具有時間間隔的表。

記錄在事件後添加，例如一個事件：十行。 但是，如果再次發生相同的事件：添加十個新行。 所以1事件：二十行。

我想找到所有出現不止一次的id爲最小值，最大值和日期/時間

我有theese兩個表的事件：

First contain : ID, EVENT_TYPE, DATE, STATE 
Second contain : ID, EVENT_NUMBER, DATA_OF_EVENT 

所以我想要兩個結果行如果事件發生2次

樣本數據：

-----------

1, T1, 20141031 10:00:00 
2, T1, 20141031 10:00:00

Answer 1

編輯，以新的請求：

select a.event_number, b.min_id, b.max_id, cast(b.date as smalldatetime) 
from table2 a inner join 
(select min(id) min_id, max(id) max_id, cast(date as smalldatetime) date, event_type 
from table1 
group by cast(date as smalldatetime), event_type) b 
on a.id=b.min_id 

從MSDN

ss是兩位數字，範圍從00到59，表示第二個。 29.998秒或更少的值向下取整至最接近的 分鐘，29.999秒或更長的值向上取整至最接近的 分鐘。
