Question

In both cases同样的事情发生了（插入/操纵数据）。但内部会发生什么？

在execute（）中传递查询：

        Class.forName("com.mysql.jdbc.Driver");

        Connection con= DriverManager.getConnection("jdbc:mysql://localhost:3306/mysql","root","dinga");

        String str="insert into student values(10,'abc',100)";

        Statement stmt=con.createStatement();

        stmt.execute(str); //Passing query in execute()

        System.out.println("Data inserted successfully");

在CreateStatement（）

中传递查询

        Class.forName("com.mysql.jdbc.Driver");

        Connection con= DriverManager.getConnection("jdbc:mysql://localhost:3306/mysql","root","dinga");

        String str="insert into student values(10,'abc',100)";

        Statement stmt=con.createStatement(str);//Passing Query in createStatement()

        stmt.execute();

        System.out.println("Data inserted successfully");

Answer 1

除了这种情况下的可读性之外没有区别：P

在createstatement（）和execute（）中传递SQL查询有什么区别？
