prepared statement - Perl: Using DBI placeholders for ORDER BY clause -

-

Can I use the placeholder in the statement prepared for the order of my inquiry section?

I am not trying to do it, and it does not seem to work, but it did not throw any errors, which seemed strange.

No, you can not use placeholder for column name. From:

With most drivers, placeholders can not be used for any element that prevents the database server from validating the statement and making a query execution plan for it. Could.

But still you can create a query in Perl. In this case, use the method to extract column names.
