Hi
I've heard 2 things recently, can I confirm if their true/false?
(1) If you have a stored procedure and you want to optimise it you can
call exec proc1,
you could also use define/set for each of the variables and copy the
code into query analyser,
this then makes it easier to tune. However the optimiser works
differently for these variables than it does for variables passed into
the query via exec and will produce a less optimal
plan
(2) There is a different optimiser used in query analyser than that
used otherwise? A colleague
had a problem where a stored procedure called from dotnet code was
running slowly but
one run from query analyser via exec, with exactly the same arguments,
was running quickly
