// Demonstrate the GroupBy() query method // This program reworks the earlier version that used // the query syntax using System; using SystemLinq; class GroupByDemo { static void Main() { string[] websites = { "hsNameAcom", "hsNameBnet", "hsNameCnet", "hsNameDcom", "hsNameEorg", "hsNameForg", "hsNameGtv", "hsNameHnet", "hsNameItv" }; // Use query methods to group websites by top-level domain name var webAddrs = websitesWhere(w => wLastIndexOf('') != 1) GroupBy(x => xSubstring(xLastIndexOf(""))); // Execute the query and display the results foreach(var sites in webAddrs) { ConsoleWriteLine("Web sites grouped by " + sitesKey); foreach(var site in sites) ConsoleWriteLine(" " + site); ConsoleWriteLine(); } } }

This version produces the same output as the earlier version The only difference is how the query is created In this version, the query methods are used Here is another example Recall the join query used in the JoinDemo example shown earlier:

Although each environment will have its own special circumstances, the following approach is generally accepted by most DBAs (see figure 4.12 for a summary): For a new deployment of SQL Server, use the latest service pack available, subject to application vendor support policies. For existing production systems, aim to apply service packs as soon as possible after their release for example, at the next available/advertised maintenance window. This will require preparation and budget to ensure the availability of test environments for regression testing. Only apply hotfixes or cumulative updates if there s a particular need that is, you re suffering from a bug or security vulnerability that s fixed in the release. If you re not in this category, wait for the next general service pack. If you re denied the chance to apply a service pack, for example, an objection to the required downtime or fear of the unknown consequences, ensure management is kept informed of the Microsoft support lifecycle for previous versions of SQL Server.

var inStockList = from item in items join entry in statusList on itemItemNumber equals entryItemNumber select new Temp(itemName, entryInStock);

This query produces a sequence that contains objects that encapsulate the name and the instock status of an inventory item This information is synthesized from joining the two lists items and statusList The following version reworks this query so that it uses the Join( ) method rather than the C# query syntax:

You can also use attributes and properties with the <dtmf> element Table 13-5 describes all the attributes that can be used with the <dtmf> element You can also use the following properties in association with the <dtmf> element: Property

// Use Join() to produce a list of item names and status var inStockList = itemsJoin(statusList, k1 => k1ItemNumber, k2 => k2ItemNumber, (k1, k2) => new Temp(k1Name, k2InStock) );

Despite the ease with which SQL Server can be installed and upgraded, adequate preparation is essential in ensuring a stable and secure platform for later use: Review the best practices from the previous chapters to ensure hardware components are designed and configured appropriately. Prior to installation, create nonadministrator domain accounts for each instance/service combination, and ensure the accounts don t have any password expiration policies in place.

Although this version uses the named class called Temp to hold the resulting object, an anonymous type could have been used instead This approach is shown next:

var inStockList = itemsJoin(statusList, k1 => k1ItemNumber, k2 => k2ItemNumber, (k1, k2) => new { k1Name, k2InStock} );

As the preceding section has explained, C# has two ways of creating queries: the query syntax and the query methods What is interesting, and not readily apparent by simply looking at a program s source code, is that the two approaches are more closely related than you might at first assume The reason is that the query syntax is compiled into calls to the query methods Thus, when you write something like
