java 連接mysql數據庫並創建表

java鏈接mysql數據庫需要驅動包，那么我們先去下載驅動包http://dev.mysql.com/downloads/connector/j/，驅動包就是一個jar包里面包含了我們要使用的類、方法等

。將下載的驅動包導入我們的項目，就可以寫程序創建我們的表了。具體可以查閱API文檔https://docs.oracle.com/javase/8/docs/api/overview-summary.html

import java.sql.*;
public class Linksql {

    //我么要執行創建表的DDl語句
    static String creatsql = "CREATE TABLE pepole("
            + "name varchar(10) not null,"
            + "age int(4) not null"
            + ")charset=utf8;";

    final static String JDBC_DRIVER = "com.mysql.jdbc.Driver";
        //指定連接數據庫的url
    final static String DB_URL = "jdbc:mysql://localhost/student";
    //mysql用戶名
    final static String name = "root";
        //mysql密碼
    final static String pwd = "pwd";
    public static void main(String[] args)
    {
      Connection conn = null;
      Statement stmt = null;
      try
      {
          //注冊jdbc驅動
          Class.forName(JDBC_DRIVER);
          //打開連接
          System.out.println("//連接數據庫");
          conn = DriverManager.getConnection(DB_URL,name,pwd);
          //執行創建表
          System.out.println("//創建表");
          stmt = conn.createStatement();
         if(0 == stmt.executeLargeUpdate(creatsql))
         {
             System.out.println("成功創建表！");
         }
         else
         {
             System.out.println("創建表失敗！");
         }
         //
          stmt.close();
          conn.close();
          System.out.println("//關閉資源");
      }
      catch(Exception e)
      {
          System.out.println("創建表失敗！");
          e.printStackTrace();
      }
    }
}
