Indeed, this would be more elegant than my solution, but this would 
require finding some common functionality between various databases 
(Firebird, PostgreSQL, MySQL, and thinking about others in the future). 
I.e. something that would be both flexible and yet (at least relatively) 
portable to all TSQLConnection descendants. I'll look into this 
tomorrow. Although I may need some help about what transaction modes can 
be expressed in PostgreSQL and MySQL. I'll see tomorrow what I can do 
(and where I will need some help :).
