I tested this driver a few weeks ago and it was 3X slower with our software
than any other MS SQL Driver.

It also had a major flaw with JDBC escape syntax (which is important if you
are writing cross DB SQL!)

I would also like to point out, call me paranoid if you so wish, but .NET
is in competition with J2EE and JDBC is a fundamental component of J2EE so
don't expect fantastic code in Microsoft's equivalent driver...and after
all the damage they have tried to do against JAVA in the past I will not
be using it any code from them since I could not trust, yes trust, the code
to not have some fundamental quirk somewhere??

The only good thing it had going was that it was free! JSQLConnect is probably
the best out there.
