But what happens with SELECT statements? Do you open a transaction per
statement? And when does the auto-commit happen?

OK, this is the value of TTransactionDesc.TransactionID I think? Is it
in my responsability, to manage the used TransactionID's? Do they
have to be unique globally or only per TSqlConnection ?
