[英]TIMESTAMPDIFF - How to use it in PHP/MySQL to calculate difference between date values
The link above have helped me how to calculate difference in two dates, however, I need to do the same on a particular column at run time via MySQL select query inside PHP. 上面的链接帮助我如何计算两个日期之间的差异,但是, 我需要在运行时通过PHP中的MySQL select查询在特定列上执行相同的操作。
For example: 例如:
Profile table: 资料表:
Running following query via MySQL console, gives exactly the needed result: 通过MySQL控制台运行以下查询,将给出所需的结果:
SELECT TIMESTAMPDIFF(YEAR, DOB, CURDATE()) AS Age FROM profile;
However, I need to complete the following query to get me the same result combined with other conditions on whole set of DOB values: 但是,我需要完成以下查询,以使我获得相同的结果,并结合整个DOB值的其他条件:
SELECT * FROM Profile WHERE Gender='$gn';
I checked Sub-query but that, wont work due to more than one return value. 我检查了子查询,但是由于返回值不止一个,因此无法正常工作。
As you said, it's the same table, you could use this query: 如您所说,它是同一张表,您可以使用以下查询:
SELECT *,TIMESTAMPDIFF(YEAR, DOB, CURDATE()) AS Age
FROM Profile
WHERE Gender='$gn';
Then you'll find an additional field age
in your result set. 然后,您将在结果集中找到一个额外的字段age
。
