Query performance problems can evolve because of inaccurate selectivity estimates made by the optimizer based on the existing distribution statistics (histograms). However, you can t always duplicate the production data in your test environment to try to reproduce the problems. In such a case you will probably nd it convenient to be able to clone the production statistics into your test environment without cloning the data. You can achieve this by using the scripting capabilities of the SQL Server Management Objects (SMO) API, speci cally, the ScriptingOptions.OptimizerData property.

The final common scenario we ll look at for dictionaries is to provide efficient storage for a sparse array A sparse array is indexed by an integer, like a normal array, but only a tiny fraction of its elements contain anything other than the default value For a numeric element type that would mean the array is mostly zeros, while for a reference type it would be mostly nulls As an example of where this might be useful, consider a spreadsheet When you create a new spreadsheet, it appears to be a large expanse of cells But it s not really storing information for every cell I just ran Microsoft Excel, pressed Ctrl-G to go to a particular cell and typed in $XFD$1000000, and then entered a value for that cell.

If you ran the previous query, you might have noticed a message type named DEFAULT and a contract named DEFAULT that contains the DEFAULT message type . These were created as a result of customer feedback that writing a simple Service Broker application wasn t very simple . If you want to write an application that just sends and receives simple messages and you want to handle all messages the same, you can use the DEFAULT message type and contract so that you don t have to define your own . In the Service Broker Data Manipulation Language (DML) commands, if you don t specify a message type or contract, DEFAULT is used .
