JDBC批处理（Batch）MySQL中的表

在数据库test里先创建表school，内容如下

向school表中一次增加多行。addBatch，executeBatch

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
import java.sql.Statement;

public class Demo {
    public static void main(String[] args) {
        Connection con=null;//连接接口
        Statement stmt=null;//语句接口
        try {
            Class.forName("com.mysql.cj.jdbc.Driver");//加载驱动类
            //test数据库地址
            String url="jdbc:mysql://localhost:3306/test?serverTimezone=UTC&characterEncoding=utf8&useSSL=false";
            con= DriverManager.getConnection(url,"root","123456");//连接数据库
            stmt=con.createStatement();//创建语句对象
            //批处理Batch
            stmt.addBatch("insert into school(id,name,sex,birthday) values (5,'jerry','男','2010-01-12')");
            stmt.addBatch("insert into school(id,name,sex,birthday) values (6,'tom','男','2009-08-15')");
            int result[]=stmt.executeBatch();//执行批处理
            System.out.println("有"+result.length+"行纪录被修改");
        } catch (ClassNotFoundException e) {
            e.printStackTrace();
        } catch (SQLException e) {
            e.printStackTrace();
        }
    }
}
