我想选择即将到来的5天过生日的所有员工。生日保存在日期字段中。感觉就像我必须使用之间,但是年份范围会破坏结果。
基本上我想在5天的范围内按月和日选择日期。
数据库方案:
CREATE TABLE IF NOT EXISTS `tbl_office_employee` (
`id` int(11) NOT NULL auto_increment,
`firstname` varchar(256) collate utf8_unicode_ci default NULL,
`surname` varchar(256) collate utf8_unicode_ci default NULL,
`birthdate` date NOT NULL,
`telephone` varchar(256) collate utf8_unicode_ci default NULL,
PRIMARY KEY (`id`)
)
有人知道一个查询来完成此任务吗?

你想在MySQL中使用这样的东西(已编辑 - 真正的工作示例):
SELECT *
FROM `tbl_office_employee` e
WHERE FLOOR(
(
UNIX_TIMESTAMP(
CONCAT(
YEAR(CURDATE()) + (DATE_FORMAT(e.birthdate, '%m-%d') < DATE_FORMAT(CURDATE(), '%m-%d')),
DATE_FORMAT(e.birthdate, '-%m-%d')))
- UNIX_TIMESTAMP(CURDATE()))
/ 86400) < 5
下面写的SQL查询没有选择明年的生日(即1月1日至1月31日),所以请使用上面的一个...
SELECT * FROM
tbl_office_employee
e WHERE UNIX_TIMESTAMP(DATE_FORMAT(e.birthdate,CONCAT(YEAR(CURDATE()),' - %m-%d')))在UNIX_TIMESTAMP(CURDATE())和UNIX_TIMESTAMP之间(DATE_ADD(CURDATE(),INTERVAL 5 D))
我必须使用UNIX_TIMESTAMP
,因为日期变化,即5月31日至6月5日(5不大于31),并在e.birthdate
更改年份。< / EM> 击>
可以在DQL(Doctrine 1)中完成:
Doctrine_Query::create()
->select('e.firtsname')
->from('tbl_office_employee e')
->where('e.date BETWEEN ? AND ?', array($today_date, $date_plus_5_days))
->getSqlQuery();
哪个输出基本相同。
我不认为开箱即用的DQL可以DATE_ADD
,但是there is chapter called DQL User Defined Functions in docs, which has example implementation of DATE_ADD
function for MySQL。
答案 1 :(得分:1)
SELECT * FROM member WHERE DATE_FORMAT(birthdate, '%m%d') between DATE_FORMAT(NOW(), '%m%d') and date_format(adddate(now(), interval 4 day),'%m%d');
或
SELECT * FROM member WHERE DATE_FORMAT(`birthdate`, '%m%d') >= DATE_FORMAT(NOW(), '%m%d') AND DATE_FORMAT(`birthdate`, '%m%d') <= DATE_FORMAT(DATE_ADD(NOW(), INTERVAL 4 DAY), '%m%d') ORDER BY DATE_FORMAT(`birthdate`, '%m%d') ASC;
或
SELECT * FROM member WHERE (1 = (FLOOR(DATEDIFF(DATE_ADD(DATE(NOW()),INTERVAL 4 DAY),birthdate) / 365.25)) -(FLOOR(DATEDIFF(DATE(NOW()),birthdate) / 365.25))) ORDER BY MONTH(birthdate),DAY(birthdate)
所有查询都经过测试。
答案 2 :(得分:0)
SELECT *,
CURRENT_DATE() + INTERVAL 5 DAY AS coming_date,
CURRENT_DATE() AS today_date
FROM tbl_office_employee
WHERE birthdate <= coming_date AND birthdate >= today_date
