SHOW [FULL] TABLES [FROM db_name] [LIKE 'pattern']
SHOW TABLES列举了给定数据库中的非TEMPORARY表。您也可以使用mysqlshow db_name命令得到此清单。
本命令也列举数据库中的其它视图。支持FULL修改符，这样SHOW FULL TABLES就可以显示第二个输出列。对于一个表，第二列的值为BASE T
web framework层出不穷，特别是ruby/python,各有10+个,php/java也是一大堆 根据我自己的经验写了一个to do list,按照这个清单，一条一条的学习，事半功倍，很快就能掌握 一共25条，即便很磨蹭，2小时也能搞定一条，25*2=50。只需要50小时就能掌握任意一种web框架
各类web框架大同小异:现代web开发框架的6大元素，把握主线，就不会迷路
建议把本文
hostname // to display the computer name
hostname <changed name> // to change
go to: /etc/sysconfig/network, add/modify HOSTNAME=NEWNAME to change permenately
dont forget to change /etc/hosts
Java代码：
public class test03 {
public static void main(String[] args) {
int[][] a = {{1},{2,3},{4,5,6}};
System.out.println(a[0][1]);
}
}
运行结果：
Exception in thread "mai
