SQL SELECT範圍內

Question

表日期：

id | u_id | start_date | end_date | 
------------------------------------- 
01 | 7 | 2015-05-05 | 2015-07-23 | 
02 | 4 | 2015-07-10 | 2015-07-15 | 
03 | 4 | 2015-08-27 | 2015-11-05 | 
04 | 5 | 2015-08-01 | 2015-12-09 | 

需要這些行：

03 | 4 | 2015-08-27 | 2012-11-05 | 
04 | 5 | 2015-08-01 | 2012-12-09 | 

我有查詢

輸入數據： start_date = 2015-10-01和end_date = 2015-10-31

Answer 1

試試這個：

SELECT id, u_id, start_date, end_date 
FROM mytable 
WHERE start_date <= @end_date AND end_date >= @start_date 

以上將返回start_date - end_date區間重疊與@start_date - @end_date的所有記錄。
