Hello Mirek,

I sorry, I have sent wrong header file. Of course, we need to add "counter" code to constructor and destructor.

MySqlSession()       { numberOfInstances++; mysql = NULL; Dialect(MY_SQL); }
~MySqlSession()      { numberOfInstances--; Close(); }

I would like to relate to putting EXITBLOCK. In my option counter method is more efficient, because memory can be free at runtime. On the other hand, EXITBLOCK will make order when the program ends. Of course, I can be wrong what EXITBLOCK is doing. I have never used it in my applications.

Well, I think that amount of memory is not high and there is plausible usage scenario where you create DB connection per request - in that case MySql will have to recreate the whole memory area....

Frankly, more I am thinking about this, perhaps the best course of action is to do nothing. This is a 'leak' we can afford.
