在 MySQL (InnoDb) 中计算年龄
如果我将某人的出生日期以 dd-mm-yyyy
形式存储在表格中,然后从当前日期中减去它,那么返回的日期格式是什么?
If I have a persons date of birth stored in a table in the form dd-mm-yyyy
and I subtract it from the current date, what format is the date returned in?
如何使用这种返回的格式来计算某人的年龄?
How can I use this returned format to calculate someone's age?
推荐答案
如果值存储为 DATETIME 数据类型:
If the value is stored as a DATETIME data type:
SELECT YEAR(CURRENT_TIMESTAMP) - YEAR(dob) - (RIGHT(CURRENT_TIMESTAMP, 5) < RIGHT(dob, 5)) as age
FROM YOUR_TABLE
考虑闰年时不太精确:
SELECT DATEDIFF(CURRENT_DATE, STR_TO_DATE(t.birthday, '%d-%m-%Y'))/365 AS ageInYears
FROM YOUR_TABLE t
