A normal database view is just a named select statement that can be used from other select statements. These views have no particular impact on performance. Beginning with SQL Server 2000, you could create one or more indexes on a view because the view satisfies certain requirements. These requirements are quite extensive and can be found in Books Online under the heading Creating Indexed Views at http://msdn2.microsoft.com/en-us/ library/ms191432.aspx. By creating an index on a view, the view is materialized. This means that, in the logical sense, it is still a view, but now that view actually stores the data found in the view. If the data is changed in the tables on which the view is based, the view is automatically updated to reflect those changes. Creating indexed views can greatly improve read performance of queries. An important aspect of indexed views is that the query optimizer can automatically detect that an indexed view that satisfies a certain query exists and can use it, even if the indexed view is referenced in the query. This, however, is only true for SQL Server 2005 Enterprise Edition and Developer Edition. The following example shows a query and its execution plan (shown in Figure 7-14) without an indexed view:

B is correct. Only OWA forms-based authentication allows you to control how attachments will be handled.

Temporary tables, as their name suggests, are temporary table structures. Temporary tables can be either global or local and can be created by any user. All temporary tables are created in the tempdb database. A local temporary table is visible only to the user who created the table and only within the connection that was used to create the table. Local temporary tables are automatically dropped when the connection they are associated with is closed. You create a local temporary table by using the CREATE TABLE command and prepending a pound sign (#) to the table name. The following example shows the command to create the earlier CustomerAddress table as a local temporary table:

8. The remaining steps in the wizard are almost identical to the steps for configuring a Web publishing rule. The only difference is that you need to choose or create a Web listener that listens for SSL requests. You can modify the SSL bridging configuration for the secure Web publishing rule after you create the Web publishing rule. If you decide that you no longer need SSL connections between the ISA Server computer and the client computers, change the Web listener to support HTTP rather than HTTPS connections. If you decide to change the SSL configuration for the ISA Server to Web server connection, access the Bridging tab on the Web Publishing Rule Properties dialog box, shown in Figure 8-17. On this tab, if you choose the option Redirect Requests To SSL Port, the connection between the ISA Server computer and the Web server will be secured. If the Web server is configured to require client certificates, you must also select Use a Certificate to Authenticate to the SSL Web Server, and select a certificate that ISA Server will use to authenticate to the Web server.

Reading this SRV record name right to left like other DNS records, it translates to:

Now, let s look at creating a simple table. Consider this example:

but will be available only on the domain controllers in the domain in which they were created until the domain functional level is raised.

An alternative to removing the documentation entirely is to use the wsdlHelpGenerator element and set the href attribute to point to a blank Hypertext Markup Language (HTML) page. When you remove the documentation for a Web service, you also dis able any automatic WSDL file generation. Unless you have a custom WSDL docu ment, pointing to a blank HTML page is a better option than removing the documentation entirely.

' Execute the query using an XML reader. Dim reader As XmlReader = cmd.ExecuteXmlReader()

Capturing Trigger Options The default Trigger On option is set to Nothing, which means no triggers will be active. You can set up a trigger to alert you under certain key conditions. For instance, you can be notified when the buffer space is 25 percent, 50 percent, 75 percent, or 100 percent full. This might be your signal to take a look and clean it out before any packets are lost because of low buffer space. You might also decide to use the handy Pattern Match feature (selected in the figure), which allows you to type in a hex or ASCII representation of what you want to find. For instance, you could look for any instance of a clear text string of characters, and then, by using the Execute Command Line option, have a message sent to you saying that your text string was found.
