PS:下面看下mysql如何查詢當天信息？
原來不是太熟悉SQL查詢語句，什么都是用到了再去查去找，還好網(wǎng)絡提供給我們很多支持。今天又用到了一個語句，一時間真想不出怎么解決，到網(wǎng)上看了看，感覺就有一個，怎么那么簡單啊。需要積累的東西真是太多了。
今天就把我這個簡單的問題記錄下來吧!算是一個積累：
mysql查詢當天的所有信息：
select * from test where year(regdate)=year(now()) and month(regdate)=month(now()) and day(regdate)=day(now())
這個有一些繁瑣，還有簡單的寫法：
select * from table where date(regdate) = curdate();
date()函數(shù)獲取日期部分, 扔掉時間部分，然后與當前日期比較即可
