worksheet. Those items would be included in the count, and would falsely increase the size of the source range, or they could cause an error when the pivot table is refreshed. Blank cells within the data in the row or column being counted would also cause a problem, reducing the size of the source range. Count a column and row where there is always a value.

<binding id="setCss" dataContext="selectStyle" dataPath="selectedValue" property="cssClass" transform="DoAdditionalHandling" /> </bindings> </label> </components> </page> </script> In this script you can see the initialization of the three components the text box, the select, and the label. The initialization of the text box is straightforward you don t need to do anything special, just point the Atlas control at the underlying HTML tag, which is called textBoxText. You don t specify an ID for the Atlas control, so Atlas gives it the default ID, which is the same as the underlying HTML ID: textBoxText. To initialize the selection list, you use the <select> tag. This is pointed at the underlying HTML <select> list, which is called selectStyle, using the targetElement attribute to specify it. On this you specify an action that occurs upon the selection change. You do this using the <selectionChanged> child tag. This in turn will call a method using the <invokeMethod> tag. The target for this method is setCSS, which, as you will see in a moment, is the name of a binding on the label element. The method attribute is set to evaluateIn, which means the data to be used in this method call is the value of the select box. You will evaluate this input to the selection box and pass that to the setCSS binding. The workhorse of this application is the label element. You can achieve the functionality I have been discussing the update of the label via binding with the text and via binding with the selection list by creating a couple of bindings on the label. The first of these bindings is associated with the element called textBoxText, which is the Atlas identifier for the text box control (see its declaration). The dataPath attribute specifies the property on that control to bind to, which in this case is its text property. The label has a text property too, and you want to update this with whatever is in the text property of the text box. Therefore, you specify the property attribute to be text. With this in place, you have now bound the label to the text box. The second binding on the label is worth another look: <binding id="setCss" dataContext="selectStyle" dataPath="selectedValue" property="cssClass" transform="DoAdditionalHandling" /> This binding has a specific ID, called setCss. You will notice that the other binding wasn t given a specific ID, because it is never being explicitly called from elsewhere. This binding, however, is called from the <invokeMethod> on the selection list. For Atlas to be able to identify it, it needs this identifier. The dataContext attribute points to the control to which you are binding. In this case you want to bind to the selection control, and it is called selectStyle.

LOAD DATA INFILE * INTO TABLE DEPT FIELDS TERMINATED BY "," (DEPTNO, DNAME, LOC ) BEGINDATA 10,Sales,Virginia 20,Accounting,Virginia 30,Consulting,Virginia 40,Finance,Virginia By far the easiest way to get started is to use this existing legacy control file to provide the definition of our external table. The following SQLLDR command will generate the CREATE TABLE statement for our external table: $ sqlldr / demo1.ctl external_table=generate_only SQL*Loader: Release 11.2.0.1.0 - Production on Thu Apr 15 13:10:37 2010 Copyright (c) 1982, 2009, Oracle and/or its affiliates. All rights reserved. $ The EXTERNAL_TABLE parameter has one of three values: 1. 2. NOT_USED: This is self-evident in meaning and is the default value. EXECUTE: This value means that SQLLDR will not generate a SQL INSERT statement and execute it. Rather, it will create an external table and use a single bulk SQL statement to load it. GENERATE_ONLY: This value causes SQLLDR to not actually load any data, but only to generate the SQL DDL and DML statements it would have executed into the log file it creates.

The logistics manager has asked for a report on the quantities per order. You created a report with Quantity in the Row Labels area, Category in the Column Labels area, and OrderDate in the Values area, as Count of OrderDate. To simplify the report, you would like to show the quantities in groups of ten, such as 1 10, and 11 20, and show the number of orders in each grouping. However, you get an error message that says, Cannot group that selection, when you try to group the numbers. You checked the source data, and no text entries are in the Quantity field. This problem is based on the GroupErrorNum.xlsx sample workbook.

Listing 27-9. Creating a More Complex Condition in a where Clause using System; using System.Collections.Generic; using System.Linq; class Listing 09 { static void Main(string[] args) { List<string> myFruitList = new List<string>() { "apple", "plum", "cherry", "grape", "banana", "pear", "mango" , "persimmon", "lemon", "lime", "coconut", "pineapple", "orange"}; IEnumerable<string> results = from e in myFruitList where e[0] == 'p' && e[1] == 'e' && e.Length > 4 select e; foreach (string str in results) { Console.WriteLine("Result item: {0}", str); } // wait for input before exiting Console.WriteLine("Press enter to finish"); Console.ReadLine(); } } The query in Listing 27-9 filters the data elements, allowing only those whose first letter is p, whose second letter is e, and whose Length is greater than four characters. Compiling and running Listing 27-9 produces the following results: Result item: persimmon Press enter to finish
