Need a correction in the original question. It shouldn't be "datetime". It should be "smalldatetime", just to avoid confusion that seems to be leading to a rather large base of people selecting the incorrect answer.

--Jeff Moden

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.

A datetime allows the time component to be 23:59:59.

Because the question asks for the maximum time stored by a datetime value and not a smalldatetime, I believe a change to the question is required.

A datetime allows the time component to be 23:59:59.

But it also allows the date component to be up to 9999-12-31, so none of the answers would be correct if you assumed that datetime was the type being tested. I agree, the question is poorly worded, but it's possible to figure out the author's intent fairly easily.

Like Paul pointed out, the question asks about the max of a datetime. Given the answers provided, it wasn't too hard to figure out. Sure, it's an inaccurate question, but how many inaccurate questions do we get from people in a day during work? 😛

I have to agree about the question wording (because we all like to whine from time to time). However, I did realize that the question was about SmallDateTime. I got it wrong because I forgot about the rounding for seconds. So, a re-learning experience and I'll take my punishment for the miss.

The wording " What's the maximum time that can be stored in SQL Server 2014?" got me. :angry:

But logically speaking, isn't it the interval from zero to 2079-06-06 23:59:00

the maximum value of the TIME in seconds that can be STORED in SS2014?

They haven't it always easy, our authors of QotD... 😉 Thanks Steve, need more coffee...:-)

Like everyone has already noted, typo on the datetime; should be smalldatetime.

I played around with it a bit.

I can stuff '20790606 23:59:29' into a smalldatetime variable and it comes back out as '20790606 23:59:00'

If I put '20790606 23:59:30' into it then it errors.

Sorry, corrected the question itself. Too used to writing "datetime".

I also don't use Datetime as it's not accurate enough. I use Date , Time & Datetime2 as these correspond to my other Database that I use ( DB2 ) which has Date , Time and Timestamp
