Hah. Yes, I understand the irony of that statement, but the point is
that the value of the variable won't change during query execution.

That's so gross... but it might work. I'm not really desperate, just
frustrated. I really can't wait until we can upgrade; 7.4 is driving
me nuts. I'm not really worried about a re-plan, since this SP just
updates a fact table, so it only gets called twice a day. Cutting the
execution time of the SP down to < 20 seconds from 15 minutes would be
nice, but not absolutely required. I was just surprised at the large
difference in manual execution as opposed to the SP with the same
query.

Agreed! When we finally upgrade, I fully plan on putting a symbolic
bullet into our old installation. ;)
Thanks!
