You can use the browser to find the tables, indexes, procedures, or any other objects in the available databases. A useful tool just for that portion. The right pane of the object browser will change appearance and content depending on what is being done. Figure 19-15 shows a simple query against the Northwind sample database that ships with SQL Server. Here we ve queried the Customers table to find all the Canadian customers, taking advantage of the fact that we know the format of the PostalCode field for a Canadian address. Probably not the most effective way to get there, since the database includes a Country field, but an example of the flexibility of the SQL language. The upper half of the right pane shows the actual query that was executed, whereas the lower half shows a grid view of the results. You can send the results of your query to a file by selecting Results To File from the Query menu, or analyze the efficiency of the query by selecting Show Execution Plan from the Query menu. The SQL Query Analyzer has a wealth of additional features that make it an invaluable tool for the database administrator (DBA) or developer who needs to tune an application or database for maximum performance. Summary In this chapter, we ve taken a brief look at the Microsoft SQL Server 2000 component of the Premium Technologies disc, especially the administrative components used to maintain the database and get data in and out of it. In the next chapter, we ll examine the tools and techniques for monitoring and troubleshooting your Microsoft Windows Small Business Server 2003 network.
