Well, the documentation for nchar and nvarchar still says that the the value can be any number from 1 to 4000 or max, and 5000 is clearly not in that range, so I was actually expecting an error, but that wasn't one of the choices.

How would that apply? Both variables are VARCHAR (or were when I looked at the question).

Cheers!

Got the answer but misread the question - did not notice the [font="Courier New"]varchar(MAX)[/font] vs [font="Courier New"]varchar(5000)[/font] !

Lesson repeated: when looking at T-SQL do not overlook details.

:blush: I guess my morning caffeine hadn't totally kicked in, yet. It's a good thing that producing an error wasn't one of the choices.

DECLARE @a VARCHAR(max) = REPLICATE('a', 10);

DECLARE @b-2 VARCHAR(10) = REPLICATE('b', 10);

SELECT LEN(@a + @b-2);

Ans : 20
