Google turns up the Oracle license right away:

About halfway down in the text box you'll find a long list of "you may not"s:

You may not:
disclose results of any program benchmark tests without our prior consent;

I didn't find the text of the SQL Server license at, but
I didn't spend that much time looking either.

(In the spirit of fairness: Oracle's claimed reason for this restriction
is that they don't want to be bad-mouthed by people who don't know what
a reasonable database benchmark is.  I've seen enough bogus benchmarks
that I can sympathize with that.  Nonetheless, writing such a thing into
your license agreement *is* an admission of weakness.  If they had
confidence in their product they could let the free market figure out
which benchmarks mean something.)
