Whatever it may look like at first sight of the execution plan, the join order for this query is t1 t2 t3 Oracle hashes t3 into memory, then hashes t1 into memory, then starts to read t2 For each row in t2 Oracle probes the t1 hash for a match, so the first join is t1 t2; and if the first probe is successful, Oracle probes the t3 hash for a match, so the second join is t2 t3 although, technically, you should say the second join is (t1 t2) t3 Our task is to work out how the optimizer got an intermediate cardinality of 62,500 for the t1 t2 hash, and how it then got a cardinality of 9,551 by joining t3 to the intermediate result set We just have to take it in steps. vb.net code 39 reader VB .

If you want to preserve and later restore the application state from some permanent storage such as a file or a database, you can do so in the global events described earlier in this section. Try It Out: Preserve and Restore the Application State You will now fix the counter so that it retains the site visitor count between application restarts. 1. The FriendsData database (provided with the code for this book) includes a table whose purpose is to hold the global counter. It s called (guess what) Counter, and contains a single column, Visitors. Open the Global.asax code-behind page, and add the following imports: Imports System.Configuration Imports System.Data.SqlClient 2. Add the following code to retrieve the counter to Application_Start(): Sub Application_Start(ByVal sender As Object, ByVal e As EventArgs) ' Get the connection string from the existing key in Web.config Dim con As SqlConnection = New SqlConnection( _ ConfigurationSettings.AppSettings("cnFriends.ConnectionString")) Dim cmd As SqlCommand = New SqlCommand("SELECT Visitors FROM Counter", con) con.Open() Try ' Retrieve the counter Application("counter") = CType(cmd.ExecuteScalar(), Integer) Finally con.Close() End Try End Sub 3. Add the following code to save the counter to Application_End(): Sub Application_End(ByVal sender As Object, ByVal e As EventArgs) ' Get the connection string from the existing key in Web.config Dim con As SqlConnection = New SqlConnection( ConfigurationSettings.AppSettings("cnFriends.ConnectionString")) Dim cmd As SqlCommand = New SqlCommand( "UPDATE Counter SET Visitors=" + Application("counter").ToString(), con) con.Open() Try cmd.ExecuteNonQuery() Finally con.Close() End Try End Sub 4. Let s modify the Session_Start() event, as the counter will always be there now, since it will be initialized by Application_Start(): This chart is a basic combination of a Category dataset and a Bar plot. Listing 13-30. JRXML Syntax <!ELEMENT barChart (chart, categoryDataset, barPlot)> -- or should this be greater( 37, 40) Sub Session_Start(ByVal sender As Object, ByVal e As EventArgs) Application.Lock() If Application("counter") Is Nothing Then Application("counter") = 1 Else Application("counter") = CType(Application("counter"), Integer) + 1 End If Application.UnLock() End Sub 5. From the Server Explorer, set an initial value on the Visitor field of the Counter table. 6. Save and run the application to see what differences the changes in the code have made. view holds. Here, for example, is a query to discover the activity against a particular data segment (the t1 table used in earlier examples in this chapter) in a 10g database: select from where ; * v$segstat obj# = 52799 How It Works The counter is now kept in the database, thus preserving it across application restarts.
