Homephp教程php手册php操作sqlserver关于时间日期读取的小小见解

上周五,要做一个php 同时对mysql数据库和sqlserver数据库的连接东东
以前一直在用mysql对sqlserver不是很熟悉,于是摸着石头过河。没有别的至少mysql和sqlserver还算是亲戚
在做条件查询的时候。出现了问题
首先是查询出来的时间是这种格式的
11 30 2009 10:20:20AM
我打开sqlserver数据库查看表中的数据
却是2009-11-30 10:20:20.233
后来查了查好像sqlserver有个格式问题,但是输出的时候要的是2009-11-01,没有办法,只能在查询出数据后自己转换一把了
在mysql下面的话
比如我想查找time在2009-11-01到2009-11-30时间段的数据
select * from table where time > '2009-11-01' and time 我就画了个虎,结果就不知道我的where跑哪去了,不起任何作用,
我想我的2009-11-01确实不好跟11 30 2009 10:20:20AM或者2009-11-30 10:20:20.233比较,至少可比性不大
于是我就转换我的2009-11-01到11 01 2009 00:00:00AM和2009-11-01 00:00:00.000
再一比更不行。在“:”出错误。这不是找不自在吗!
于是别别扭扭的找了一天也没有点恍然小悟,不能因为这个小小问题,影响我的形象吧,今天天早早的就醒了,
昨天找到了sqlserver的时间转换函数convert包括好多种,就是没有2009-11-01这种格式,也不知道是我笨还是我笨
没有办法,只能中和一下,首先将2009-11-01转换成20091101然后将11 30 2009 10:20:20AM或者2009-11-30 10:20:20.233转换成20091130然后再比较,
别说,还真有结果了
select * from table where convert(varchar(10),date_time,112) ! $end_date
(! 也差点绊我个跟头)
