一、操作数据库 www.2cto.com
1、查看数据库
show databases [ like ''];
示例：
mysql> show databases;
+--------------------+
| Database |
+--------------------+
| information_schema |
| luomian |
| mydb |
| mysql |
| net80576314 |
| phpcms_uat |
| phpcmsv9 |
| phpcmsv9_new |
| rutiao |
| szwalkers |
| test |
| v9test1 |
+--------------------+
mysql> show databases like 'php%';
+-----------------+
| Database (php%) |
+-----------------+
| phpcms_uat |
| phpcmsv9 |
| phpcmsv9_new |
+-----------------+
2、创建数据库
create database [if not exists] dbname;
示例：
3、选择需要的数据库
use dbname
示例：
mysql> use mydb;
Database changed
4、删除数据库

| Tables_in_test |
+-----------------------+
| newname |
| productnotes |
| test_char |
| test_inn |
| test_inn2 |
| test_priority |
| test_trans |
| test_view |
+-----------------------+
2、创建表
示例：
mysql> create table user(
-> id int(10) not null auto_increment primary key,
-> name varchar(50) default 'N/A' not null,
-> sex char(1) null
-> )engine=InnDB;
3、复制表

mysql> rename table teacher to senior_teacher;
mysql> alter table student rename to senior_student;
5、删除表
mysql> drop table if exists senior_teacher;
6、查看创建表语句
mysql> show create table student;
+---------+-------------------------------------
| Table | Create Table

| student | CREATE TABLE `student` (
`id` int(10) NOT NULL DEFAULT '0',
`name` varchar(50) NOT NULL DEFAULT 'N/A',
`sex` char(1) DEFAULT NULL
) ENGINE=MyISAM DEFAULT CHARSET=latin1 |
+---------+-------------------------------------
