Sure, except that the content of the database is out of my control -
this particular scenario (where nearly all the records matched a
particular key, but the query was first run against a different key)
could easily arrise in a production environment. More to the point,
I've seen no evidence that I'm getting any performance benefits from
using parameterized queries.
I suspect I will at least add a configuration option to avoid
parameterized queries (relatively straightforward, as I have a layer of
code that handles query parameters) if I see a problem like this again.
