Summary of connecting eclipse to MySQL database

1. Create a database in MySQL, create a table, and insert data into the table

1. Create a database

create database select_test

2. Create a table

create table teacher_table(    Id int,    Name Varchar(20),    Sex Varchar(2)    )

3. insert data to the table (three test data items are inserted here)

insert into teacher_table values(1,'zhangsan','ma');insert into teacher_table values(2,'lisi','fe');insert into teacher_table values(3,'wangwu','ma');

　　

2. Configure eclipse.

Download the mysql-connector-java-5.1.15-bin.jar file before configuring.

Right-click the project where the package is located, build path ---> Configure build path, and select Add external jars in the pop-up window. Select the mysql-connector-java-5.1.15-bin.jar you downloaded and extracted.

 

 

3. Write the connection code.

Database Name: select_test

Username: Root

Password 123456

After the connection is successful, data in the teacher_table table is displayed.

import java.sql.*;class ConnMySql {/** * @param args * @throws Exception  */public static void main(String[] args) throws Exception {// TODO Auto-generated method stubClass.forName("com.mysql.jdbc.Driver");Connection conn = DriverManager.getConnection("jdbc:mysql://127.0.0.1:3306/select_test","root","123456");Statement stmt =  conn.createStatement();ResultSet rs = stmt.executeQuery("select * from teacher_table");while (rs.next()) {System.out.println(rs.getInt(1) + "\t"+rs.getString(2) + "\t"+rs.getString(3) );}if (rs != null) {rs.close();}if (stmt != null) {stmt.close();}if (conn != null) {conn.close();}}}

Summary: Elipse connecting to the MySQL database requires the download of the mysql-connector-java-5.1.15-bin.jar file.
