The proper date column has produced the right answer (nearly); the error is the usual one of the optimizer using arithmetic appropriate to continuously varying values when we are really handling a relatively small list of discrete values Oracle understands what dates are, what they mean, and how to do arithmetic with them But what s gone wrong with the numeric and character versions Nothing, really we ve just hidden from the optimizer the fact that they are really holding dates, so the optimizer has used the standard arithmetic on a data set that is a little peculiar Remember the standard formula for a range in this case using the version that is closed at both ends (between is a short-hand for '>= X and <= Y'). 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 . Let s apply it for the numeric case: Selectivity = (required range) / (high value - low value) + 2/num_distinct = (20030105 - 20021230) / (20041231 - 20000101) + 2/1827 = 8875 / 41130 + 2/1827 = 0215779 + 0001095 = 0216874 -- more than 20% of the data apparently! To finish things off, multiply the selectivity by the number of rows in the table (1,827) and we get 1,827 * 0216874 = 396228 The optimizer doesn t know that we are dealing with dates, so although we see numbers that we can recognize as a date range that crosses a month boundary or a year boundary, the optimizer doesn t see this as the next day, it simply sees a huge gap and we haven t given the optimizer any information about gaps It s inevitable that the arithmetic will go wrong. vb.net code 39 reader C# .

In the beginning, JasperReports started with only the JDK 1.2 compatible report compiler. Then the JDK 1.3 compatible report compiler was introduced. But both were slow. This is why the net.sf.jasperreports.engine.design.JRJikesCompiler was created, because the Jikes compiler proved to be up to ten times faster than the JDK-based Java compiler. However, compiling reports on the fly (in the cases in which dynamic report templates were required) proved to be problematic, especially in a web environment, because all the aforementioned compilers worked only with files on disk and required a temporary working directory to store the generated Java source files and the corresponding class files during the report-compilation process. This is why a new implementation was added one that relied on the BeanShell library for runtime expression evaluation. BeanShell does not produce Java bytecode and can work with in-memory scripts that it interprets at runtime. With the net.sf.jasperreports.engine.design.JRBshCompiler, deployment was simpler, but expression evaluation was slower and loss in performance was noticeable. The addition of the JDT-based report compiler makes the whole process both faster and simpler to deploy, as it does not require files on disk and its performance is comparable to Jikes. Runtime report compilation is not an issue anymore, and simply putting the supplied /lib/jdt-compiler.jar file in the application s classpath allows dynamic report template creation without requiring any further settings. Now the BeanShell report compiler has been removed from the core library and is shipped only as a sample, since the advantages it offered are part of the JDT-based compiler, which is now the recommended one. Figure 3-13. The Calendar Auto Format dialog box lets you apply predefined designs to the control. 3. In the Select a scheme list, choose the Simple format for the Calendar control. (Feel free to experiment with the different built-in formats.) Then click OK. 4. Through the Properties browser, set the Calendar DayNameFormat property to Short, so that the names of the days in the calendar appear as localized short names. 5. Set the page as the start page, and then run it (press Ctrl+F5) to test the results. To make it easier to show that the value of 457 reported for the character types in older versions is following the standard formulae, I created a PL/SQL function to apply the conversion algorithm I described earlier on in the chapter (see script char_funsql in the online code suite) Consequently, I can just run the following SQL statement to work out the cardinality:. How It Works The first step sets the culture to use during execution of the current request. This is done by creating a new CultureInfo object based on the preferred culture specified by the user through the browser. This information is exposed by the Context.Request.UserLanguages property. Note that you re just trying to change the current language. Things may fail at this point, for example, because the user doesn t have a user language selected, or because the client browser sent wrong data for that value, or for some other reason.
