One very common question asked by interviewers is:

CAST versus CONVERT in SQL Server


And even if it was, it would be a lousy one.
If I'd want to check syntax and functionalities, I'd look it up in BOL, not memorize it.

It is quite good question for initial telephonic interview. And you can give simple answer by
1. CONVERT is SQL speicific but CAST is ANSI standarised
2. CONVERT deal nicely with datetime using format, which is missing from CAST


1. You mean specific to the TSQL dialect.
2. In that case, a better question would be: "How would you format a datetime value to the ISO compliant format?"

The name is indeed, quite dead. I decided it was time to grow up and lose the nickname I invented when I was 12 years old :-)
But the avatar remains! :-D

That's a shame - it was quite a snappy nom de plume. My nickname aged 12 was much more offensive and would probably get me censored on SSC! Now I've just got to work out how to pronounce your surname Hehe

Are you asking us so that you can update your blog? If so, do some research, start with the indexing articles I wrote for this site.

It has to cover the query, and it's created the same way you create any index. I guess I'm not clear on what you're asking here. The only difference between a covering index and a non-covering index is the match-up between columns in the query and columns in the index being complete or incomplete.
