PS:下面看下mysql如何查詢當(dāng)天信息？
原來(lái)不是太熟悉SQL查詢語(yǔ)句，什么都是用到了再去查去找，還好網(wǎng)絡(luò)提供給我們很多支持。今天又用到了一個(gè)語(yǔ)句，一時(shí)間真想不出怎么解決，到網(wǎng)上看了看，感覺(jué)就有一個(gè)，怎么那么簡(jiǎn)單啊。需要積累的東西真是太多了。
今天就把我這個(gè)簡(jiǎn)單的問(wèn)題記錄下來(lái)吧!算是一個(gè)積累：
mysql查詢當(dāng)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(gè)有一些繁瑣，還有簡(jiǎn)單的寫法：
select * from table where date(regdate) = curdate();
date()函數(shù)獲取日期部分, 扔掉時(shí)間部分，然后與當(dāng)前日期比較即可
