Loved the question and got it right because I had issues with some old code before.
Thank you for this straightforward question!

Nice question. And this is why we always declare lengths for variable data types.

I knew about VARCHAR defaulting to length of 1, but I learned today about the CASE/CAST 30 byte truncation.

So.

Anyone know why MS created two different default data lengths? It seems like redundant inconsistency....

Who knows. The cause of this is likely buried somewhere in the past.

I think I chose the right answer and still got it wrong. Is there a way I can confirm which answer I chose?

Thank you,

I always declare the length so I wasn't sure what the defaults were but assumed that was what the question was about.

Good question.
