yes.

I have a question, too: if you are the Bill Todd who posts to the Borland
newsgroups, what is the status of the new DBExpress driver for MySQL? The
problem in old drivers was that they established a new connection for each
individual SQL statement. Transactions and several other MySQL features did
not work because of that.

I saw some 4 weeks ago a Borland engineer mention that this is now fixed in
a beta release of the driver. Is this so?
