Question

一个表包含以下数据条目：

mm_id, mm_interval, mm_interval_type, mm_start_date, mm_start_hour, mm_end_hour
3,     14,          3,                2013-07-15,    08:22,         03:55

mm_interval是“每个” mm_interval_type是

array(
1=>"Hour", 
2=>"Day", 
3=>"Week", 
4=>"Month", 
5=>"Year" 
)

现在，我正在寻找的是一种选择与当前日期匹配的条目。

我想我会用结果来改变这个问题; - ）

SELECT
  mm.*,
    mm_recurrence_settings.*
FROM
    mm
LEFT JOIN mm_types USING (mm_type_id)
LEFT JOIN mm_recurrence_settings USING (mm_id)
WHERE
    SELECT
        CASE
            WHEN mm_recurrence_settings.mm_reoc_interval_type = 1 THEN DATE(NOW()) BETWEEN DATE(DATE_ADD(mm_recurrence_settings.mm_reoc_start_date, INTERVAL mm_recurrence_settings.mm_reoc_interval HOUR)) AND CURDATE( )
            WHEN mm_recurrence_settings.mm_reoc_interval_type = 2 THEN DATE(NOW()) BETWEEN DATE(DATE_ADD(mm_recurrence_settings.mm_reoc_start_date, INTERVAL mm_recurrence_settings.mm_reoc_interval DAY)) AND CURDATE( )
            WHEN mm_recurrence_settings.mm_reoc_interval_type = 3 THEN DATE(NOW()) BETWEEN DATE(DATE_ADD(mm_recurrence_settings.mm_reoc_start_date, INTERVAL mm_recurrence_settings.mm_reoc_interval WEEK)) AND CURDATE( )
            WHEN mm_recurrence_settings.mm_reoc_interval_type = 4 THEN DATE(NOW()) BETWEEN DATE(DATE_ADD(mm_recurrence_settings.mm_reoc_start_date, INTERVAL mm_recurrence_settings.mm_reoc_interval MONTH)) AND CURDATE( )
            WHEN mm_recurrence_settings.mm_reoc_interval_type = 5 THEN DATE(NOW()) BETWEEN DATE(DATE_ADD(mm_recurrence_settings.mm_reoc_start_date, INTERVAL mm_recurrence_settings.mm_reoc_interval YEAR)) AND CURDATE( )
        END as newDate

这就是它的所在......

我的想法是使用BETWEEN迭代我的间隔。但是，唉，我只进行了第一次迭代。

也许是存储过程或？

基于重现的SQL语句
