Very nice question though I got it wrong.
I was thinking because of only 3 bit column, it should take 1 byte only same as tinyint.

Thanks

Really very nice question. Gets the mind thinking about the internal storage and is a very, very important consideration for capacity planning.
I got it right, but I must admit that it was only because of two points:
1. I am currently trying to understand database compression
2. I just read about this in Books On Line (It's hardly been two days!)

Great question, great discussion sure to follow! I am looking forward to following the entire thread.

Have a wonderful rest-of-the-day!

Thanks & Regards,

Great question, thank you.

I answered wrong by assuming there is no place for compressing bit fields more than it already does, in this case to one byte, I should have thought about the header.

Have a great day,
Iulian

Nice question - I thought they would all be the same size as well.

Interesting, I knew there was an overhead to data compression but went for TinyInt over Bit.

Good question, thanks for taking the time to help educate the SQL community.

Hope this helps,
Rich
