Like EOAdaptor. A few categories for your specific needs would have  
done the task. Do you really think that its impossible to inject SQL  
into EOF??? :-)

It *also* provides a low-level API. EOF is built in separate layers,  
the "JDBC connect" (adaptor layer) is just one of them.

Because GDL also has SQClient builtin for something like 10+ years.  
Just build the EOAdaptor layer as a framework and add the hooks you  
need.
And why? It should be rather obvious why code reuse is a good thing :-)

Sorry, but this is utter non-sense. Its like saying that you have to  
use and include AppKit just because you are using Foundation. EOF is  
a layered framework and if you don't need EOInterface, don't link it.  
And if required you could have made it even more modular instead of  
dropping the (well tested!) code.


I think the real issue was "finding" the relevant part of EOF. You  
look 5min on the EOF2 API, you get bored and think its overkill  
(because the docs *do* focus on ORM), you don't care and continue  
building own stuff.

Writing the stuff from scratch isn't hard and its fun, so its done  
(wow, that even rhymes ;-) And now that you have it its even easier  
to justify (now that we have its harder to drop it because it would  
just be additional effort)


Oh well, oh well, what an evil cycle of utterly useless reinvention :-)

Greets,
