  Question of the Day

Today's question (by Steve Jones - SSC Editor):

 

Merry Christmas 2019

I want to calculate the total number of gifts from the song, The Twelve Days of Christmas. I have this code:
WITH myTally(n)
AS
(SELECT n = ROW_NUMBER() OVER (ORDER BY (SELECT null))
 FROM (VALUES (1), (2), (3), (4), (5), (6), (7), (8), (9), (10)) a(n)
  CROSS JOIN (VALUES (1), (2), (3), (4), (5), (6), (7), (8), (9), (10)) b(n)
)
SELECT SUM(x)
FROM myTally
WHERE n <= 12
With which piece of code should I replace SUM(x)?

  Yesterday's Question of the Day (by Steve Jones - SSC Editor)

Knocking off early

It's the day before Christmas, and everyone in the Redgate office in the UK is knocking off at noon. I want to know when I can stop working in the US, since everyone else in the UK will go home.

I have this code set up:

DECLARE @t DATETIMEOFFSET = '2019-12-24 12:00+00:00'

What should I add to my SELECT below to determine the time in Colorado (7 hours behind) that I can safely stop working?

SELECT

Answer: @t AT TIME ZONE 'US Mountain Standard Time'

Explanation: The AT TIME ZONE function allows me to convert a time from another time zone to my own. In this case, I don't even have to go to work. They'll knock off at 5:00am my time. Merry Christmas and Happy Holidays. I'll see you Thursday. Ref: AT TIME ZONE - https://docs.microsoft.com/en-us/sql/t-sql/queries/at-time-zone-transact-sql?view=sql-server-ver15
