PS: 下面看下 mysql 如何查询当天信息?
原来不是太熟悉 SQL 查询语句,什么都是用到了再去查去找,还好网络提供给我们很多支持。今天又用到了一个语句,一时间真想不出怎么解决,到网上看了看,感觉就有一个,怎么那么简单啊。需要积累的东西真是太多了。
今天就把我这个简单的问题记录下来吧! 算是一个积累:
mysql 查询当天的所有信息:
select * from test where year(regdate)=year(now()) and month(regdate)=month(now()) and day(regdate)=day(now())
这个有一些繁琐,还有简单的写法:
select * from table where date(regdate) = curdate();
date() 函数获取日期部分, 扔掉时间部分,然后与当前日期比较即可
