The following is a typical (and rather inefficient) Select statement for the pubs database. It works with the Authors table, which contains a list of authors: SELECT * FROM Authors The asterisk (*) retrieves all the columns in the table. This isn t the best approach for a large table if you don t need all the information. It increases the amount of data that has to be transferred and can slow down your server. The From clause identifies that the Authors table is being used for this statement. The statement doesn t have a Where clause. This means all the records will be retrieved from the database, regardless of whether it has 10 or 10 million records. This is a poor design practice, because it often leads to applications that appear to work fine when they re first deployed but gradually slow down as the database grows. In general, you should always include a Where clause to limit the possible number of rows (unless you absolutely need them all). Often, queries are limited by a date field (for example, including all orders that were placed in the last three months). The statement doesn t have an Order By clause. This is a perfectly acceptable approach, especially if order doesn t matter or you plan to sort the data on your own using the tools provided in ADO.NET.

This technique can be used to create partially updating web sites that are more responsive than a complete page reload The XHR component is a way to send data Usually, this data is encoded in XML; however, there is no hard requirement that XML be used to encode data for transport Because of this flexibility and the relative weight of processing XML, most applications would benefit from a simpler data format, and thus JSON was packaged JSON, short for JavaScript Object Notation, is a data-encoding format that is based on JavaScript itself In fact, JSON datagrams can be evaluated as if they were code using the eval() function, and as such, require almost no processing on the client side to decode.

site maps, but it also supports showing information from a database and filling portions of the tree on demand (and without refreshing the entire page). But most important, it supports a wide range of styles that can transform its appearance.

Here s another example that retrieves a list of author names: SELECT au_lname, au_fname FROM Authors WHERE State='CA' ORDER BY au_lname ASC Only two columns are retrieved (au_lname and au_fname). They correspond to the first and last names of the author. A Where clause restricts results to those authors who live in the specified state (California). Note that the Where clause requires apostrophes around the value you want to match, because it s a text value.

The TreeView has a slew of properties that let you change how it s displayed on the page. One of the most important properties is ImageSet, which lets you choose a predefined set of node icons. (Each set includes three icons: one for collapsed nodes, one for expanded nodes, and one for nodes that have no children and therefore can t be expanded or collapsed.) The TreeView offers 16 possible ImageSet values, which are represented by the TreeViewImageSet enumeration. For example, Figure 14-10 shows the same RevoStock navigation page you considered earlier, but this time with an ImageSet value of TreeViewImageSet.Faq. The result is help-style icons that show a question mark (for nodes that have no children) or a question mark superimposed over a folder (for nodes that do contain children).

An Order By clause sorts the information alphabetically by the author s last name. The ASC part (for ascending) is optional, because that s the default sort order.

Figure 14-10. A TreeView with fancy node icons You ll notice that this TreeView makes one more change. It removes the indentation between different levels of nodes, so all the sitemap entries fit in the same narrow column, no matter how many levels deep they are. This is accomplished by setting the NodeIndent property of the TreeView to 0. Here s the complete TreeView markup: <asp:TreeView ID="TreeView1" runat="server" DataSourceID="SiteMapDataSource1" ImageSet="Faq" NodeIndent="0" > </asp:TreeView>

Here s one last example: SELECT TOP 100 * FROM Sales ORDER BY ord_date DESC This example uses the Top clause instead of a Where statement. The database rows will be sorted in descending order by order date, and the first 100 matching results will be retrieved. In this case, it s the 100 most recent orders. You could also use this type of statement to find the most expensive items you sell or the best-performing employees.
