Nice question ..... and it teaches something additional ... it teaches one to read definitions as well as the T-SQL very, very closely

If everything seems to be going well, you have obviously overlooked something.

Great question.
Although, the first X returned is not just X but X with 19 spaces. SSMS doesn't really show it that well, but if you copy paste the value you'll see the spaces.

A very good question, even if i missed it. :-P
I thought, if the LEN delivers 1, then the LIKE makes the same. For me a bit inconsistent, but good to know how stuff works.

Excellent question. I often come across code such as

IF col1 like col2 (without any wildcards)

and I've often wondered why they didn't just put IF col1=col2. Til today I assumed they were equivalent. (I wonder if those that wrote this code appreciate the nuance.)

Thanks for expanding my knowledge.

Nice question!

However, the explanation and reference are slightly incomplete, as they don't explain the behaviour of @A LIKE @B versus @ LIKE @A.
The explanation for that can simply be found in the Books Online article on LIKE, in the "Remarks" section. Link: http://msdn.microsoft.com/en-us/library/ms179859.aspx

Nice question.

When we print the variables we can see the padded space in @A.

PRINT @A
PRINT @B
PRINT 'A:'+@A + 'B:'+ @B+':'
