Yeah Chris, you would win a handful of Lindt chocky balls which I'm giving away as prizes for good answers. 3km was a reasonable guess, as most people think it's a few hundred metres or so.
And Ben, my grain of sand I picked up from Mentone beach is 0.700000000000mm in diameter, and it's a perfect Silicon Dioxide sphere of course. Another question I ask is how many grains of sand are in the jar (PHOTO LINK <http://www.docuscope.com.au/temp/sand.jpg> ). The book pictured behind the jar is book 1 of the pair T-SQL Querying and T-SQL Programming. I accidentally bought book 2 first and found it discussed things like triggers, performance and rarer topics like spatial data, auditing (by Greg Low), service broker, etc. A lot of that wasn't of much interest to me as a pure developer, so I rushed out and bought book 1. I must now report that the book 1 is very heavy and dense reading with a lot of maths and algorithm discussions that I guess would be university course level. If you just want to be a good T-SQL and proc coder then there are probably many books that are easier to digest. If you're a bit geeky and like full coverage and deep technical background information then I think the pair of Inside SQL Server 2008 books will tickle your fancy. Cheers, Greg
