1.把出生日期字符串转换为日期格式. public static Date parse(String strDate) throws ParseException { SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd"); return sdf.parse(strDate); } 2.计算年龄 public static int getAge(Date birthDay) throws Exception { Calenda

以前使用mysql不是很多,对mysql的函数也不是很熟悉,遇到这个问题第一时间百度搜索,搜索到这两种方法,这两种方法是排在百度第一条的博客. 方法一 SELECT DATE_FORMAT(FROM_DAYS(TO_DAYS(NOW())-TO_DAYS(birthday)), '%Y')+0 AS age 方法一,作者也说出了缺陷,就是当日期为未来日期时结果为0,而不是负数:这里使用了5个函数和两个运算符. 方法二 SELECT DATE_FORMAT(NOW(), '%Y') - DATE_

先从String类型的出生日期(“yyyy-MM-dd”)中提取int类型的年.月.日:再计算岁数. 程序如下: /** * 根据出生日期计算年龄的工具类BirthdayToAgeUtil */ public class BirthdayToAgeUtil { private static String birthday; private static String ageStr; private static int age; //出生年.月.日 private static int year

我这边有一个业务,需要客户填写身份证号,自动计算他的出生日期和年龄 在sql中,具体的存储过程实现是这样的: /*********************************************** 根据身份证号计算出生日期和年龄 Date:2017-10-15 Author:xzl 条件:身份证号码 返回:出生日期和年龄 ***********************************************/ /*** *根据身份证号计算出生日期和年龄 ***/ create

=IF(MONTH(NOW())<MONTH(G4),INT(YEAR(NOW())-YEAR(G4))-1,IF(MONTH(NOW())>MONTH(G4),YEAR(NOW())-YEAR(G4),IF(DAY(NOW())>=DAY(G4),YEAR(NOW())-YEAR(G4),YEAR(NOW())-YEAR(G4)-1))) 此公式用于根据出生的年.月.日精确的计算年龄,G4单元格填写的是出生日期

根据生日计算年龄可以通过Calendar实现.最简单可以考虑get(Calendar.DAY_OF_YEAR)来简单修正年龄,但是遇到生日在闰年的2月29之后,或者今年是闰年的2月29之后可能出现计算不准,误差一天.所以还是老实判断年月日好了. // 根据生日计算年龄,判断了年月日,比简单的年份上计算更精准 public static int getAge(Date birthDay) throws Exception {         Calendar cal = Calendar.getI
