01, the optimizer reported card = 3,000 The last test was the most surprising when you create a frequency histogram, the density is always set to 1/(2 * num_rows) But there seems to be a bit of optimizer code that deals with the possibility that someone has been messing about with the density, and has set it so high that one of the known values in the frequency histogram is apparently going to return fewer rows than an unknown value that is not in the histogram Clearly, this could be a very convenient way to identify up to 254 specific values in a column, and then set a figure for the number of rows that the optimizer should allow for every other value that might be used when querying this column with a constant. vb.net code 39 reader VB .

NET Code 39 barcode Reader Control is an advanced developer-library for . NET class ... NET Code 39 barcode scanner can read barcode images using VB . Since subreports are normal reports themselves, they are compiled and filled just like other reports. This means that they also require a data source from which to get the data when they are filled. They can also rely on parameters for additional information to use when being filled. There are two ways to supply parameter values to a subreport. You can supply a map containing the parameter values, as when filling a normal report with data, using one of the fillReportXXX() methods exposed by the JasperFillManager class (see 3). To do this, use the <parametersMapExpression> element, which introduces the expression that will be evaluated to obtain the specified parameters map. This expression should always return a java.util.Map object in which the keys are the parameter names. In addition to (or instead of ) supplying the parameter values in a map, you can supply the parameter values individually, one by one, using a <subreportParameter> element for each relevant parameter. To do this, specify the name of the corresponding parameter using the mandatory name attribute and provide an expression that will be evaluated at runtime to obtain the value for that particular parameter, the value that will be supplied to the subreportfilling routines. Note that you can use both ways to provide subreport parameter values simultaneously. When this happens, the parameter values specified individually, using the <subreportParameter> element, override the parameter values present in the parameters map that correspond to the same subreport parameter. If the map does not contain corresponding parameter values already, the individually specified parameter values are added to the map. vb.net code 39 reader C# .

Of course, the usual problems of bind variables, bind variable peeking, and joins have to be taken into account.. If we take our sample data set from the previous section and create a histogram with 75 buckets (script c_skew_ht_01.sql in the online code suite), we can notice small, but significant, details in the results that get stored in the data dictionary: begin dbms_stats.gather_table_stats( user, 't1', cascade => true, estimate_percent => null, method_opt => 'for all columns size 75' ); end; / In this chapter, you started to add some data-aware pages to your application, which allowed you to leverage the power of data-driven pages. We discussed how to programmatically access a database and handle its data. You were able to display that data in web forms, taking advantage of the techniques you learned about in previous chapters. Up to now, however, you have been typing a lot of code manually. VS .NET goes much further in programmer productivity, introducing the key concept of components. In the next chapter, we ll discuss this concept, and you ll discover what components are and how they work in conjunction with the IDE to perform some automatic coding tasks. We ll also dig into some exciting new features introduced by VS .NET to simplify web forms and data interaction through data binding. You ll learn how to use the more advanced wizards provided by components, and how to leverage web server controls to display and edit data in highly customizable ways through the use of another technique: templates. select num_distinct, density, num_buckets from user_tab_columns where and ; table_name = 'T1' column_name = 'SKEW' vb.net code 39 reader Visual Studio .
