Hmmm...until I read this I would swear that variable binding was the neatest & surest way to handle all manner of quotes in fields. Certainly there is a lot of flakiness around DBI quote handling - so maybe there is some database dependency in what works where. You could try using the $quoted_string = $dbh->quote($string); method which should provide dialect neutral quote handling. I guess this is what DBI uses internally so it may give you an insight into what is happening.

You say that the failing examples are in the form 'text' - I would guess that quote returns 'text' when you pass it "'text'" because mostly that is what people want and that you really want '''text''' because you want to preserve leading & trailing single quotes.

So once you have checked that I do not lie, using quote. Then you could special case this with an re...

$name =~ s/^\'(*.)\'$/'''$1'''/ or $dbh->quote($name);
