我需要获得所有相同且低于2012-12-28的记录我使用了下面的查询,booking_time是DATETIME字段,并且记录小于2012-12-28,但它返回零行.有没有人有想法？

SELECT * FROM ctx_bookings WHERE DATE(booking_time)<=2012-12-28 ORDER BY id ASC

表提交

+---------------------+
| booking_time        |
+---------------------+
| 2012-12-20 03:10:09 |
| 2012-12-25 02:10:04 |
+---------------------+

请有人知道为什么会这样吗？

我是ruby和rails的新手,我在ubuntu中安装了rails.但是当我通过键入"rails s"进入启动服务器时,它不会启动并跟随消息.但我可以通过命令rails new new_project创建一个新项目.请rails专家帮帮我.

root@ubuntu:~# rails s Usage: rails new APP_PATH [options] Options: -j, [--javascript=JAVASCRIPT] 
# Preconfigure for selected JavaScript library # Default: jquery -m, [--template=TEMPLATE] # Path to an application template (can be a filesystem path or URL) [--dev] 
# Setup the application with Gemfile pointing to your Rails checkout -J, [--skip-javascript] # Skip JavaScript files [--edge] 
# Setup the application with Gemfile pointing to Rails repository -G, [--skip-git] 
# Skip Git ignores and keeps -d, [--database=DATABASE] 
# Preconfigure …

当我给出命令"rails s"以下错误时,请帮助我!我仍然在rails项目中,然后给出这个命令

我安装了joomla 2.5正版安装,但是JQuery无法正常工作.我怎样才能让jQuery在joomla中工作？默认的JQuery库是不是和joomla一起出现的？

我需要在鼠标悬停时显示图像的工具提示.我为此编写了以下代码.我当前的问题是,当我将图像放入工具提示div时,事件仅发生在图像元素上.如何从父工具提示div的子元素中忽略mouseover和mouseout事件？

$("document").ready(function() {
        $('.tooltip').mouseover(function(e){
            var id = $(this).siblings('.tooltip-c').attr('id');
            $('.tp'+id).fadeIn(500);
            $('.tp'+id ).mouseout(function(event){
                $('.tp'+id).fadeOut(300);
            });
        });
    });

请帮帮我们.我很无奈.
