The quoting may confuse an editor (it does confuse the perl.vim code).

First, and most important, you should use placeholders instead of inserting Perl variables directly into SQL. Your code will break, for example, if HTTP_USER_AGENT or HTTP_REFERER contain an apostrophe (both of these values are under user control). Serious security risks can occur if you ignore this issue. For info, google SQL injection.

As a minor matter, you can avoid quoting literal hash keys if they are made up of all word characters (i.e. match /^\w+$/). For example, you can say <code>$Session->{idSession}. I see you did that one place.
