Finding Day Number from the Beginning of the Year
I want to start with this simple question that was posted today (May 31, 2013) 
- how to find today's date day number from the beginning of the year.
This is my solution and a bit of explanation at the end
DECLARE@curDate DATE= CURRENT_TIMESTAMP;DECLARE@YearStart DATE= dateadd ( year ,datediff(year, '19000101', @curDate) ,'19000101' );SELECTdatediff(day, @YearStart, @curDate) + 1 AS[Number ofDays fromthe Year Start]
=====================
Thanks again to Naomi!
