There are several ways.

At a command prompt (DOS prompt, etc.) type this:

perl -MSQL::Statement -e "print $SQL::Statement::VERSION"

Or write a small script like this:

use SQL::Statement;
print $SQL::Statement::VERSION;

The code you showed should definitely work in any SQL::Statement newer than three or four years old (I should know, I am it's author). So you may be best off to just reinstall it and get a new version. If you keep having problems, post here, don't give up. Good luck!
