Variable column names using prepared statements

I was wondering if there was any way to specify returned column names using prepared statements.

I am using MySQL and Java.

When I try it:

String columnNames="d,e,f"; //Actually from the user...
String name = "some_table"; //From user...
String query = "SELECT a,b,c,? FROM " + name + " WHERE d=?";//...
stmt = conn.prepareStatement(query);
stmt.setString(1, columnNames);
stmt.setString(2, "x");

I get this type of statement (printing right before execution).

SELECT a,b,c,'d,e,f' FROM some_table WHERE d='x'

I would, however, like to see:

SELECT a,b,c,d,e,f FROM some_table WHERE d='x'

I know that I cannot do this for table names, as discussed here, but was wondering if there was some way to do it for column names.

If there is not, then I will just have to try and make sure that I sanitize the input so it doesn't lead to SQL injection vulnerabilities.
