JDBC 創(chuàng)建數(shù)據(jù)庫

JDBC教程 - JDBC創(chuàng)建數(shù)據(jù)庫

以下代碼顯示如何使用JDBC連接在MySQL數(shù)據(jù)庫中創(chuàng)建數(shù)據(jù)庫。

用于創(chuàng)建數(shù)據(jù)庫的SQL如下所示。

CREATE DATABASE STUDENTS

代碼首先加載驅(qū)動程序，然后與數(shù)據(jù)庫建立連接。

然后它創(chuàng)建一個Statement并發(fā)出create database命令。

例子

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

public class Main {
  static final String JDBC_DRIVER = "com.mysql.jdbc.Driver";
  static final String DB_URL = "jdbc:mysql://localhost/";

  static final String USER = "username";
  static final String PASS = "password";

  public static void main(String[] args) throws Exception {
    Connection conn = null;
    Statement stmt = null;

    Class.forName(JDBC_DRIVER);
    conn = DriverManager.getConnection(DB_URL, USER, PASS);
    stmt = conn.createStatement();

    String sql = "CREATE DATABASE STUDENTS";
    stmt.executeUpdate(sql);
    System.out.println("Database created successfully...");

    stmt.close();
    conn.close();
  }
}
