1、新建一個java project

2、開啟file裡的project structure，開啟libraries，點選＋號，選擇java，在idea中新增外部jar包——jar包選擇DmJdbcDriver18.jar；

如果需要原生jdbc，匯入這一個jar包即可；（有沒有jdbc jar包，我忘了。。。應該沒有吧，jdbc是一種介面規範，DmJdbcDriver18.jar就是實現這種介面規範的類。）

3、正常原生jdbc使用

package com.ssy.dao;

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

public class Test {

    public int insert() throws ClassNotFoundException, SQLException {
        //1.regedit driver
        Class.forName("dm.jdbc.driver.DmDriver");
        //2.get connection
        Connection connection = DriverManager.getConnection("jdbc:dm://localhost:5236","SYSDBA","SYSDBA");
        
 
//3.excute sqlstring
        String sqlString = "insert into SYSDBA.TB(id, book) values(131,'dsaf');";
        java.sql.Statement  statement = connection.createStatement();
        int exSta = statement.executeUpdate(sqlString);
        if (statement != null)
        {
            statement.close();
        }
        
 
return exSta;
    }

    public static void main(String[] args) throws SQLException, ClassNotFoundException {
        Test t = new Test();
        t.insert();
    }
}
