String dbUser="root";
String dbPwd="1234";
//建立数据库连接
con = java.sql.DriverManager.getConnection(dbUrl,dbUser,dbPwd);
//创建一个JDBC声明
stmt = con.createStatement();
//增加新记录
stmt.executeUpdate("INSERT INTO books (id,name,title,price) VALUES ('999','Tom','Tomcat Bible',44.5)");
//查询记录
rs = stmt.executeQuery("SELECT id,name,title,price from books");
