Re: Problems with question marks in operators (JDBC, ECPG, ...)

I certainly don't disagree it's a good idea for connectors to have an escaping mechanism, but the problem here is that there's a blurred line regarding whose magic it is. It would make sense for connectors to allow for their magic to be escaped, but it turns out that the magic they do is a very close match to what seems to be in the SQL spec under the Dynamic SQL section.
It could be argued that ? should be always escaped anyway, even in a direct SQL query, simply not to make it conflict with Dynamic SQL, but there doesn't seem to be such a mechanism in the SQL spec as far as I can see (and always having to escape the end result doesn't really make sense).
