Well, the context is somewhat more complex, and I just simply
won't get that piece of information about the kind of statement
from my caller before the time of me calling prepareStatement(...).
"Not getting the information" implies, that the caller also
won't instantiate different classes of my package beforehand,
nor will call different methods of my classes beforehand.

ResultSets, updateCounts and generated keys are supposed to be kept
available for later request (through getters), except for the general
success feedback (as in: exception thrown or not) which is "delivered"
immediately, so I also can't just defer execution until the first 
getter gets called.

That may all sound a bit like "mission impossible" now...
Eventually, peeking into the sql string might be my only way out,

It's nice of the JDBC to offer a general execute() suitable for 
both modification statements and queries, but unfortunately they
didn't follow that concept to its end.
