mysql - 如何从表中获取基于月份和年份的记录？

Question

我们可以在 where 子句中仅使用日期的月份和年份部分来过滤日期字段吗？

    SELECT `outlet`.`outlet`,cities.`city`,teritory.`teritory`,region.`region`,`countries`.`country` FROM `audit`
    JOIN `user` ON `user`.`id`=`audit`.`auditor_id`
    JOIN `user_outlet` ON `user_outlet`.id=`audit`.`outlet_id`
    JOIN `outlet` ON `outlet`.id=`user_outlet`.`outlet_id`
    JOIN `cities` ON `cities`.`id`=`outlet`.`city_id`
    JOIN `teritory_city` ON `teritory_city`.`city_id`=`cities`.id
    JOIN `teritory` ON `teritory_city`.`teritory_id`=`teritory`.`id`
    JOIN `region` ON `region`.`id`=`teritory`.`region_id`
    JOIN `org_country` ON `org_country`.`id`=`region`.`org_country_id`
    JOIN `countries` ON `countries`.`id`=`org_country`.`country_id`
    WHERE `audit`.`created_date`=?

上面是我试过的查询，我必须传递年和月参数而不是传递日期。在 UI 中，年和月是我提供给用户的唯一过滤器，用于获取特定月份和年份的相应数据。

使用 year() 和 month() 函数，如下所示-

SELECT `outlet`.`outlet`,cities.`city`,teritory.`teritory`,region.`region`,`countries`.`country` FROM `audit`
JOIN `user` ON `user`.`id`=`audit`.`auditor_id`
JOIN `user_outlet` ON `user_outlet`.id=`audit`.`outlet_id`
JOIN `outlet` ON `outlet`.id=`user_outlet`.`outlet_id`
JOIN `cities` ON `cities`.`id`=`outlet`.`city_id`
JOIN `teritory_city` ON `teritory_city`.`city_id`=`cities`.id
JOIN `teritory` ON `teritory_city`.`teritory_id`=`teritory`.`id`
JOIN `region` ON `region`.`id`=`teritory`.`region_id`
JOIN `org_country` ON `org_country`.`id`=`region`.`org_country_id`
JOIN `countries` ON `countries`.`id`=`org_country`.`country_id`
WHERE year(`audit`.`created_date`)=yearparam and month(`audit`.`created_date`)=monthparam
