Craig,
Without overloading you have two choices:
1. Have a separate function that you have to call depending on the number of parameters.
2. Always pass all parameters.Doesn't seem to worry those who extol the virtues of Stored Procedures. ;-)
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
