How to parametrize fields of a SELECT statement?

问题

Is there a way to parametrize fields of a SELECT statement using PreparedStatement or other utilities?

I mean something like:

SELECT ?, ? FROM MY_TABLE WHERE ? = ?

回答1:

No, JDBC does not let you do that. The idea behind parameters is to speed up execution and avoid SQL interjections; parameterizing the columns that you are selecting does not help either of these two goals.

Try with the following
