Hello,

   I just discovered the new classe TTreeSQL. I tried to use it with a code such as :

TSQLServer *s = TSQLServer::Connect("mysql://dbserv/db","user","pwd"); TTreeSQL *t = new TTreeSQL(s,"db","atable");

   But then it crashes my session probably because the "atable" table is too big. Is TTreeSQL dumping the whole table with the constructor TTreeSQL ? This is a problem while accessing to very big tables ( > 1 Go ). Which way should I use in such a case ?

   Thank's in advance,

                                Tristan
