獲取值每天都在特定的月份（或間月）

Question

可能重複：
Get a list of dates between two dates

這是我的SQL：

select * from table as t 
where DateAndTime BETWEEN '2011-03-01' AND '2012-01-25' 

問題： *例如，我需要從2012年1月起每天（週末除外）獲取數據。

我該怎麼辦？

Answer 1

SELECT 
    * 
FROM 
    yourtable AS T 
WHERE 
    yourdatetimefield BETWEEN STR_TO_DATE('2012-01-01', '%Y-%m-%d') AND 
           STR_TO_DATE('2012-12-31', '%Y-%m-%d') 
AND 
    DAYOFWEEK(yourdatetimefield) <> 1 AND ' Sunday 
    DAYOFWEEK(yourdatetimefield) <> 7  ' Saturday 
GROUP BY 
    DAY(yourdatetimefield); 

Answer 2

試試這個。

SELECT * 
from table as t 
where (DateAndTime BETWEEN '2011-03-01' AND '2012-01-25') AND 
     DateAndTime NOT IN ('2011-03-03', '2011-03-10') -- Put the excempted 
                 -- dates here 

Answer 3

select * from table as t 
where DateAndTime BETWEEN '2011-03-01' AND '2012-01-25' 
AND (DATEPART(weekday, DateAndTime) <> 1 and DATEPART(weekday,DateAndTime) <> 6) 

(DATEPART(weekday, DateAndTime) = 1是星期天 (DATEPART(weekday, DateAndTime) = 6是星期六
