I tried on Sql 2005,

Msg 139, Level 15, State 1, Line 0

Cannot assign a default value to a local variable.

Msg 137, Level 15, State 2, Line 4

Must declare the scalar variable "@str1".

Am I testing it in a wrong way?

the answer is only correct when using SqlServer 2012 and above. Previous versions prompt an error.

if you try this on 2005 you will need to split the variable assignment, try this:

@str1 VARCHAR(5)

,@str2 VARCHAR(10) ;

select @str1 = NULL, @str2 = 'SQL Strings';

2008 is quite enough.

In-line assignment was introduced in version SQL 2008

DECLARE

{

{ @local_variable [AS] data_type | [ = value ] }

| { @cursor_variable_name CURSOR }

} [,...n]

Prior to SQL 2008, declaration and assignment happens in two different lines.

While yes, initial assignment was introduced in SQL 2008, I think the point of the question was what it prints out and the data types involved. I thought it was a good question that raised a good point.
