java – 如何在Eclipse中使用MySql数据库

OTOH,如果你想知道如何使用JDBC连接到mysql数据库,下面的代码示例解释了它.

Connection connection = null;
        try {
            //Loading the JDBC driver for MySql
            Class.forName("com.mysql.jdbc.Driver");

            //Getting a connection to the database. Change the URL parameters
            connection = DriverManager.getConnection("jdbc:mysql://Server/Schema","username","password");

            //Creating a statement object
            Statement stmt = connection.createStatement();

            //Executing the query and getting the result set
            ResultSet rs = stmt.executeQuery("select * from item");

            //Iterating the resultset and printing the 3rd column
            while (rs.next()) {
                System.out.println(rs.getString(3));
            }
            //close the resultset,statement and connection.
            rs.close();
            stmt.close();
            connection.close();
        } catch (SQLException e) {
            e.printStackTrace();
        } catch (ClassNotFoundException e) {
            e.printStackTrace();
        }
