I really doubt that this could work. From DBI's POD:

"With most drivers, placeholders can't be used for any element of a statement that would prevent the database server from validating the statement and creating a query execution plan for it"

And if it works, it should be a literal substitution, so probably can't be used to avoid sql injection

I, in my code, use plain old sprintf to build the query when I need to change table or column names and bind only the scalar values

Obviously everything is included with sprintf must be validated if coming from outside the script
