　MySql常用命令总结

　　1、使用SHOW语句找出在服务器上当前存在什么数据库：

　　mysql> SHOW DATABASES;

　　2、创建一个数据库MYSQLDATA

　　mysql> CREATE DATABASE MYSQLDATA;

　　3、选择你所创建的数据库

　　mysql> USE MYSQLDATA; (按回车键出现Database changed 时说明操作成功!)

　　4、查看现在的数据库中存在什么表

　　mysql> SHOW TABLES;

　　5、创建一个数据库表

　　mysql> CREATE TABLE MYTABLE (name VARCHAR(20), sex CHAR(1));

　　6、显示表的结构：

　　mysql> DESCRIBE MYTABLE;

　　7、往表中加入记录

　　mysql> insert into MYTABLE values (”hyq”,”M”);

　　8、用文本方式将数据装入数据库表中(例如D:/mysql.txt)

　　mysql> LOAD DATA LOCAL INFILE “D:/mysql.txt” INTO TABLE MYTABLE;

　　9、导入.sql文件命令(例如D:/mysql.sql)

　　mysql>use database;

　　mysql>source d:/mysql.sql;

　　10、删除表

　　mysql>drop TABLE MYTABLE;

　　11、清空表

　　mysql>delete from MYTABLE;

　　12、更新表中数据

　　mysql>update MYTABLE set sex=”f” where name=’hyq’;
