SQL Server, trying to get day of week via a deterministic UDF.
Im sure this must be possible, but cant figure it out.
UPDATE: SAMPLE CODE..

Not sure what you are looking for, but if this is part of a website, try this php function from http://php.net/manual/en/function.date.php
function weekday($fyear, $fmonth, $fday) //0 is monday
{
return (((mktime ( 0, 0, 0, $fmonth, $fday, $fyear) - mktime ( 0, 0, 0, 7, 17, 2006))/(60*60*24))+700000) % 7;
}
