I'm a SQL lover, but I think it's been shown over and over that there
are cases where "native" IO blows the doors of SQL. 

HOWEVER, you must also take a step back and look at the problem from a
different point of view. I've seen cases where SQL was substituted for a
CHAIN or a SETLL/READE and it was "shown" that the result was slower
than the native IO. But the real question is, would you have even needed
that CHAIN if you'd looked at the problem from a SQL point of view and
used a join? Or would you need to read all those records if you looked
at the problem from a SQL point of view and used a "sum(fld1) group by
fld2" SQL statement.

SQL is damn fast in set oriented tasks, the real trick is to see if you
can rework the initial question to be set oriented instead of trying to
make SQL solve a problem that's not set oriented. SQL really doesn't
mind 10-way joins w/subselects, and sometimes that's how you need to
look at the problem.
