I don't know about the first question, but as for this second one - yes.  make 
sure to link the .dll against Qt's sql libraries (ie, QT += sql in the .pro 
file...if you have one), and also to include the proper qt database headers in 
DLL .h or .cpp files.
you might want to pass by reference, or pass a pointer or something...
