I have a query that is extraordinarily slow but I don't know why.
It looks like spview is a view with an embedded ORDER BY? IIRC that

WHERE-IN-sub-SELECT is a kind of join.
Thanks for the pointer Tom; removing the ORDER BY from the view did
the trick. Is there a reason that the sorting can't be done after the
selection? I suppose I can solve this with a function.
