Installing MySQL Download MySQL 4.0.17 at:

http://www.mysql.com/get/Downloads/MySQL-4.0/mysql-4.0.17-win.zip/from/http://mysql.orst.edu/

Unzip “mysql-4.0.1-win.zip” and execute “setup.exe”

Choose a directory, select typical install options.

Once installation is complete, go to your autoexec.bat file

and put: SET MYSQL_HOME=C:\mysql

SET PATH =%MYSQL_HOME%\bin;%PATH%

-where “C:\mysql” is the location where you installed mysql.

Once mysql is installed, and your variables are setup,

you need to install the mysql server “service”. To do this type:

C:\mysql\bin> mysqld --install //installs the service

C:\mysql\bin> NET START MYSQL //start the mysql server

Connecting to the MySQL Server

• SYNTAX: mysql -h host -u user -p << EXAMPLE >>

C:\mysql\bin> mysql –h localhost –u root –p

NOTE: THE DEFAULT PASSWORD FOR ROOT IS BLANK !!!

Changing “ROOT” password GET USER FIRST:

C:\mysql\bin> mysql -u root mysql

CHANGE PASSWORD SYNTAX:mysql> UPDATE user SET Password=PASSWORD('new_password') WHERE user='root'; mysql> FLUSH PRIVILEGES;

DON NOT FORGET THE “ ; “ semi-colon

Interfacing with MySQL Server

• The command-line is too cumbersome, we need a GUI!!

• Enter the MySQL Control Center

• Download at: http://www.mysql.com/get/Downloads/MySQLCC/mysqlcc-0.9.4-win32.zip/from/http://mysql.orst.edu/

• Unzip mysqlcc-0.9.4-win32.zip and install:

• Open Control Center and Register your MySQL Server

• NAME: Any name you want

• HOST: DNS NAME OR IP-ADDRESS of MySQL SERVER

• USERNAME: Usually root

• PASSWORD: Leave blank, UNLESS you changed it.

Hack the GUI on your own time!

Interfacing with Java: Important Points• Use ConnectorJ “JDBC Driver”

• Include mysql-connector-java-3.0.10-stable-bin.jar in your java project

• Import com.mysql.jdbc.Driver;

• Get to know the java.sql.* Package!

Understand “DriverManager” and its relationship with a “Connection”.

OTHER CLASSES OF USE:
