Question

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

这是我的sql：

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

问题： *例如，我需要从2012年1月开始每天获取数据（周末除外）。

我该怎么做？

Answer 1

试试这个。

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 2

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

SELECT
    * 
FROM
    yourtable AS T 
WHERE

                              STR_TO_DATE('2012-12-31', '%Y-%m-%d')
AND 
    DAYOFWEEK(yourdatetimefield) <> 1 AND    '  Sunday
    DAYOFWEEK(yourdatetimefield) <> 7        '  Saturday 
GROUP BY
    DAY(yourdatetimefield);
