a nice car I wrote a newsletter and lectured I never expected to end up in life where I am now He attributes his ability to create indicators to seeing the world differently than other people I started as an art major in college, so I m a very visual person Because of my art background I ve been trained to look and see patterns While the average person might see a graph, I see colors and shades and bugs crawling around It s not that I m gifted; I was fortunate enough to be trained He remembers asking a friend about a list he saw of the most active stocks in the newspaper What does this mean I asked my friend He told me that if you bought a stock yesterday, today you would have made $100 Back in 1962, $100 was like a thousand dollars today So I told him, You mean if I do this I don t have to go to work That s for me! It looked so easy Well, I ve been working hard at it ever since Although Williams creates mathematical indicators, he insists he s not a mathematician He notes that I m primarily a trader who is attracted to that $1 to $2 a day People have probably written more about my indicators than I ever did The reason he created his indicators was to help determine when the market was overbought or oversold on a short-term basis I was just trying to survive, he remembers

on page one. If the folder contains millions of phone numbers, this would not be feasible. The folder is analogous to a clustered index in SQL Server. The folder contains all the information that is available, and the phone number acts as the key to unlock it providing order to the information and a way of identifying each individual record. The White Pages is useful for finding Andrew s phone number, though. I know Andrew s surname, so I can find him very quickly. As it s sorted by surname, I can turn straight to his record (almost I might have to jump around a little) and see his phone number there. As I only need his phone number, the White Pages (but I d rather call it a nonclustered index) is the only resource I need. I can say that it covers my query. But if I wanted to get another piece of information, such as his billing number, I d have to use his phone number to look him up in the master folder. In SQL Server land, this is known as a key lookup. I won t go further into indexes now. Entire chapters could be written about best practices for indexes, and I want to make a point about unused indexes.

When Script Assistant has uniquely identified the term you re typing, or has identified the most likely term, it enters the term in your code without asking you The part that Script Assistant has entered appears in gray, and the insertion point remains after the last character you typed You can accept the suggestion by pressing ESC or F5, or reject the suggestion by typing through it

If I never used the White Pages, there would be no point in having it in that small cupboard on which the phone sits. I could put other, more useful stuff there. What s more, whenever someone moves or changes his name or phone number, the White Pages must be updated. Although I get a new physical copy only once a year, the online version is updated much more often. Perhaps if I were eager, I could keep my eye out for changes to the underlying data and keep my copy of the White Pages up to date. But that would be arduous. The same principle applies to indexes in databases. If we don t use an index, there s little point in having it around. Learning how to find the indexes that aren t used is a fairly useful skill for a database administrator to pick up, and SQL Server 2005 makes this easier. SQL Server 2005 introduced Dynamic Management Views (DMVs) that are useful for providing dynamic metadata in the form of queryable views. There are other types of system views, such as catalog views like the useful sys.indexes, but for finding out which indexes are used, the most useful view is the DMV sys.dm_db_index_usage_ stats. Let s look at the structure of this view, by expanding the relevant part of the Object Explorer in SQL Server Management Studio (SSMS), which is in the System Views section under the database of interest. Figure 1 comes from SQL Server 2008 Management Studio, even though my queries are running against SQL Server 2005. I m also using administrator access, although you only need VIEW DATABASE STATE permission to read from the DMV.
