摘要: 1. 安装vnc
rpm -ivh vnc-server-4.1.2-14.el5_3.1.i386.rpm
rpm -ivh vnc-4.1.2-14.el5_3.1.i386.rpm


3. 设置vnc server的访问密码
[ann@ecdev1 ~]# vncpasswd

3. 执行vncserver,第一次执行后会生产一些配置文件

4. 修改/home/ann/.vnc/xstart（如果无此文件，就运行vncserver）
#!/bin/sh
# Uncomment the following two lines for normal desktop:
unset SESSION_MANAGER
exec /etc/X11/xinit/xinitrc

SQL like子句的另一种实现方法,速度比like快


一般来说使用模糊查询，大家都会想到LIKE
select * from table where a like '%字符%'

如果一个SQL语句中用多个 like模糊查询，并且记录条数很大，那速度一定会很慢。

select * from table where patindex('%字符%',a)>0
select * from table where charindex('字符',a)>0
经测试这两种方法比LIKE速度要快。
