And the explanation doesn't mention why inserting NULL in another string doesn't result in NULL, but in an empty space instead.
That's what got me.
Surely it's a bug?
select 'Vinay, ' + NULL + ', Amit'
returns NULL, so I'd have thought
select STUFF('Vinay, Vijay, Amit',8,5,NULL)
should do the same?
That's exactly my reaction. The BoL page quoted states that the last expression is inserted in the other, and I'm pretty sure that sticking a NULL in the middle of a string should produce NULL. If it doesn't, I would regard it as a bug unless there were a clear statement in BoL that this operation on NULL was unlike any other in SQL (if there is such a statement, I haven't found it). I wonder if it's affected by the CONCAT_NULL_YIELDS_NULL setting?

Wow... that didn't work quite the way I'd expected it to! Nice question!
(And I'm really glad I checked my answer in SQL before actually answering the question!)

Another ticky tack problem. Sure, I said 2, because the results were the same, just in a different order. It was the last of the two matching result sets. (No order by clause, so order doesn't matter.
)
By the way, what setting in SQL Server Management Studio must I have set that required me to put semicolons at the end of each command before they would run without error?
Please don't go. The drones need you. They look up to you.

I answered correctly, but there was 2 same answers and I choose the wrong one
Or is there some difference between those 2 answers?
1. Vinay, Anup, Amit 2. Vinay, , Amit 3. NULL
1. Vinay, Anup, Amit 3. NULL 2. Vinay, , Amit
