| | | Happy Thanksgiving 2017 Happy Thanksgiving to the US SQLServerCentral community. I hope you have a wonderful holiday and you're not working today. For the rest of the world, I hope it's a quiet Thursday, all your queries run fast, and nothing causes you any undue stress. Today is a day that used to be almost universally celebrated in the US, with most businesses being closed. This day used to be close to Christmas, and a good day for most of the country to relax and enjoy time with family. Certainly some people always need to staff certain positions, and there were often restaurants and leisure businesses, like movie theaters, that were open. That's changed a bit, with more businesses being open, and some companies even starting Christmas sales today, ahead of Black Friday. For me this will be a day off, relaxing with family as my kids will be here, back from college and work, to have some family fun. A nice meal, some games, maybe a movie at home. At least, I hope we'll stay home. All the travel for me this year has me enjoying the moments I get at home. Today should be a nice day to recharge for me, and I hope a good one for you as well.

| | | Today's Question (by Steve Jones): The Chargers-Cowboys game that takes place today will start at 3:30 in Dallas, TX. I've got the time stored in a variable DECLARE @d DATETIME2 = '20171123 3:30pm' If I am in Denver, I want to be sure plan dinner around the game. How can I get the time the game starts? Hint: Dallas is in the Central Time Zone, Denver is in the Mountain Time Zone. I will run the query in the Mountain Time Zone. |

| | Yesterday's Question of the Day |
| Yesterday's Question (by Steve Jones): I have this code, which creates two variables a <- array(1:12, dim = c(3, 4)) b <- 1:12 This gives me a matrix and a vector, as seen here: > a [,1] [,2] [,3] [,4] [1,] 1 4 7 10 [2,] 2 5 8 11 [3,] 3 6 9 12 > b [1] 1 2 3 4 5 6 7 8 9 10 11 12 If I run this, what happens? a == b
Answer: A matrix of 12 TRUE values Explanation: R will attempt to compare variables that are nearly equal with the == operation. If we used the identical() function, this compairson would fail. Since the values can be matched up by R, the comparson will return a matrix of 12 TRUE values.
