Our warehouse is fairly large, which geospatial data type should we use?

Fabiano launches into a sound technical explanation of the way that the query optimiser works in SQL Server with a mention of Brazilian Soccer stars and young ladies on Copacabana beach. You'll never quite think of statistics, execution plans, and the query optimiser the same way again after reading this, but we think you'll understand them better.

It would be nice if we could use the DBCC PAGE command to see exactly what it is stored at the page level, however, in order to do this we need to find a way to correlate the results returned from a SELECT statement with the physical data location. Is that possible? The answer is: YES. All we need to do is use the sys.fn_physLocFormatter function. In this tip, I will cover how to use this undocumented function.

'Help, my database ate my disk drives!'. Many DBAs spend most of their time dealing with variations of the problem of database processes consuming too much disk space.

What can we use in SQL instead of E. F. Codd's T theta operators for best-fit? Joe Celko returns with another puzzle that isn't new, in fact it already features “Swedish”, “Croatian” and “Colombian” solutions in chapter 17 of Joe's 'SQL for Smarties' book. These were all written before CTEs or the new WINDOW functions. Is there now a better solution? Was there one even then? We leave it to the readers to provide the answer!
