我用的是mysql绿色版。在http://www.oracle.com/index.html点击download下载masql。在MySQL Enterprise Edition 目录下点击Download from Oracle eDelivery 进登录入进行下载。
设置环境变量:在path环境中加入D:\mysql\bin;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;C:\Program Files (x86)\Java\jdk1.8.0_11\bin
设置配置文件:
# For advice on how to change settings please see

#
*** DO NOT EDIT THIS FILE. It‘s a template which will be copied to the

default location during install, and will be replaced if you
# *** upgrade to
a newer version of MySQL.
[mysqld]
#
Remove leading # and set to the amount of RAM for the most important data
#
cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.
#
innodb_buffer_pool_size = 128M
#
Remove leading # to turn on a very important data integrity option: logging
#
changes to the binary log between backups.
# log_bin
#
These are commonly set, remove the # and set as required.
basedir =
"D:/mysql/"
datadir = "D:/mysql/data/"
# default-character-set=utf8
#
port = 3306
# server_id = .....
#
Remove leading # to set options mainly useful for reporting servers.
# The
server defaults are faster for transactions and fast SELECTs.
# Adjust sizes
as needed, experiment to find the optimal values.
# join_buffer_size =
128M
# sort_buffer_size = 2M
# read_rnd_buffer_size = 2M
mysql_args="--explicit_defaults_for_timestamp"
sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES
完成后保存。
进入命令行输入窗口(Dos命令输入)进入“D:\mysql\bin”目录下运行“mysqld -u root” 命令。
设置密码:mysqladmin -uroot password 密码;
登录数据库:mysql -uroot -p密码 ;
显示数据库:show databases ;
解决乱码问题:
建立数据库:create database mldn character set utf8 ;
建立数据表:
--选择数据库
USE
test ;
--删除表
DROP TABLE member;
--创建表
CREATE TABLE
member(
mid INT AUTO_INCREMENT ,
name VARCHAR(20) NOT NULL
,
CONSTRAINT pk_mid PRIMARY KEY(mid)
)engine=innodb;
--测试数据
INSERT
INTO member(name) VALUES(‘咯咯了‘) ;
SELECT * FROM member LIMIT0,5;
建立一个新的数据库:
--删除数据库 DROP DATABASE IF EXISTS mldn ; --创建数据库 CREATE DATABASE mldn CHARACTER SET UTF8 ; --使用数据库 USE mldn ; --删除数据表 DROP TABLE IF EXISTS emp ; --创建数据表 CREATE TABLE emp( empno INT(4) PRIMARY KEY, ename VARCHAR(10), job VARCHAR(9), hiredate DATE, sal FLOAT(7,2) ) ; --插入测试数据 INSERT INTO emp (empno,ename,job,hiredate,sal) VALUES (6060,‘华‘,‘经理‘,‘2001-09-16‘,2000.30) ; INSERT INTO emp (empno,ename,job,hiredate,sal) VALUES (7369,‘楠‘,‘销售‘,‘2003-10-09‘,1500.90) ; INSERT INTO emp (empno,ename,job,hiredate,sal) VALUES (8964,‘祺‘,‘分析员‘,‘2003-10-01‘,3000) ; INSERT INTO emp (empno,ename,job,hiredate,sal) VALUES (7698,‘张惠‘,‘销售‘,‘2005-03-12‘,800) ; INSERT INTO emp (empno,ename,job,hiredate,sal) VALUES (7782,‘军‘,‘分析员‘,‘2005-01-12‘,2500) ; INSERT INTO emp (empno,ename,job,hiredate,sal) VALUES (7762,‘明‘,‘销售‘,‘2005-03-09‘,1000) ; INSERT INTO emp (empno,ename,job,hiredate,sal) VALUES (7839,‘月‘,‘经理‘,‘2006-09-01‘,2500) ;
--显示数据
select * from emp ;
--显示数据库
show datadases ;
