Good question, thanks!
Though I probably would have had the second option be 5, 2, 3...

One easy point for me!
How to post forum questions.
Need an answer? No, you need a question.
What’s the deal with Excel & SSIS?

This one got me. I selected 5,5,5 because I'm used to having padding spaces with the CHAR datatype. That's why I use Varchar instead when the contents of the column doesn't contain a consistent number of characters.
if you were to select them without the LEN function, you would get
abcde ab... ab...
(the period was used to make spaces visible).

It's probably also worth pointing out that if you actually did want the physical length of the variables, you would use DATALENGTH() instead of LEN().

Aargh!! Again my initial reaction was "that's easy it's 5,2,2 as LEN ignores spaces"... and then "hmmm, but that's too easy, there must be a trick in there"... and after a bit of reading went against my initial conclusion...
Doh!!
Good lesson though... trust yourself!

Yep, it only does an RTRIM, not an LTRIM.

This variation to the question may have been a better teaser
