just a quick comment: as SQL query is inherently a text string, I'm not sure
what value a new class would add - any class representing a text string
(including TString) seems to be qute sufficient. I think it is always better
to keep an interface (to everything, including relational DB's) as thin as
possible and not to invent a new language where the existing one would
suffice..
Anton's sugestion is nice, and if most of what you're coding is the
DB queries, you'd really like to have exactly this form of the interface.
However for all the practical purposes `Form` addresses the need in [may be]
a little bit less elegant but the same little bit more general way.
