如何在Java程序中訪問mysql數據庫中的數據並進行簡單操作?

參考代碼:

包數據庫編程;

導入Java . SQL . *;

公共類數據庫連接{

公共靜態void main(String[] args)引發SQLException{

//1.加載驅動程序

嘗試{

class . forname(" com . MySQL . JDBC . driver ");

} catch(ClassNotFoundException e){

// TODO自動生成的catch塊

e . printstacktrace();

}

//2.創建與數據庫的連接

//連接字符串

string URL = " JDBC:MySQL://192.168.1.101:3306/Java數據庫?用戶= root & amp密碼=胡敏”;

connection con = driver manager . get connection(URL);

//讀取和寫入

如果(!con.isClosed()){

System.out.print("歡迎使用數據庫!\ n您想做什麽.........................\ n ");

語句ST = con . create statement();

ResultSet RS = ST . execute query(" select * from stu ");

while(rs.next()){

system . out . print(RS . getstring(" stuid ")+","+rs.getString("name")+","+rs.getString("sex")+","+rs.getString("age")+","+rs.getString("address")+","+RS . getstring(" tel ")+" \ n ");

}

}

//關閉數據庫

con . close();

}

}
