1 打开mysql,创建数据库
Create database gongzibiao
2 调用数据库,并且创建表salary1
Use gongzibiao
create table salary1(id int ,name varchar(50),department varchar(50),salary int);
3 导入外部txt数据
LOAD DATA LOCAL INFILE 'e://qing.txt' INTO TABLE salary1;
4 查看表
Select*from salary1;

5 导出到eclipse,下载jar包。
6 在eclipse中新建java项目,命名为sqldemo,将jar包导入到该项目中。在该项目中建立java源文件,命名为emp.java,源文件的代码如下:
java
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;
public class emp {
public static void main(String[] args) {
//声明Connection对象
Connection con;
//驱动程序名
String driver = "com.mysql.jdbc.Driver";
//URL指向要访问的数据库名mydata
String url = "jdbc:mysql://localhost:3306/gongzibiao";
//MySQL配置时的用户名
String user = "root";
//MySQL配置时的密码
String password = "1234567890";
//遍历查询结果集
try {
//加载驱动程序
Class.forName(driver);
//1.getConnection()方法,连接MySQL数据库!!
con = DriverManager.getConnection(url,user,password);
if(!con.isClosed())
System.out.println("Succeeded connecting to the Database!");
//2.创建statement类对象,用来执行SQL语句!!
Statement statement = con.createStatement();
//要执行的SQL语句
String sql = "select * from salary1";
//3.ResultSet类,用来存放获取的结果集!!
ResultSet rs = statement.executeQuery(sql);
System.out.println("-----------------------------");
System.out.println("执行结果如下所示:");
System.out.println("-----------------------------");
System.out.println("工号"+ "\t"+"姓名" + "\t" + "部门"+"\t"+"薪资");
System.out.println("-----------------------------");
String department = null;
String name = null;
String id = null;
String salary = null;
while(rs.next()){
department = rs.getString("department");
name = rs.getString("name");
id = rs.getString("id");
salary = rs.getString("salary");
//输出结果
System.out.println(id+"\t"+name + "\t"+department+ "\t" + salary );
}
rs.close();
con.close();
} catch(ClassNotFoundException e) {
//数据库驱动类异常处理
System.out.println("Sorry,can`t find the Driver!");
e.printStackTrace();
} catch(SQLException e) {
//数据库连接失败异常处理
e.printStackTrace();
}catch (Exception e) {
// TODO: handle exception
e.printStackTrace();
}finally{
System.out.println("数据库数据成功获取!!");
}
}
}
4.数据导入eclipse的结果如下图所示
