************MOSS 关于SPQuery 和SPSiteDataQuery的区别好用法！ *********

　　　　　下面的代码是给在做ＭＯＳＳ开发的同行们的一些对象模型的学习，和自己的看法
　　　　MOSS 关于SPQuery 的用法，是关于列表的查询范围比较的小。。　
　　　　 SPWeb web = (new SPSite("http://moss/sites/hello")).OpenWeb();
SPList list = web.Lists["test"];
SPQuery query = new SPQuery();
query.Query = "<Where><Contains><FieldRef Name='Title'/><Value Type='Text'>4</Value></Contains></Where>";
SPListItemCollection items = list.GetItems(query);
foreach(SPListItem item in items)
Console.WriteLine(item.DisplayName);
　　　　SPSiteDataQuery的是查询整个Site的范围比SPQuery大，我就不在这里罗嗦拉，大家看拉代码测试一下，就很明白拉
SPWeb web = (new SPSite("http://moss/sites/hello")).OpenWeb();
SPSiteDataQuery query = new SPSiteDataQuery();
query.Query = "<Where><Contains><FieldRef Name='Title'/><Value Type='Text'>4</Value></Contains></Where>";
query.Lists = "<Lists BaseType='0' />";
query.Webs = "<Webs Scope='Recursive' />";
query.ViewFields = "<FieldRef Name='Title' /><ProjectProperty Name='Title' /><ListProperty Name='Title' />";
DataTable dt = web.GetSiteData(query);
Console.WriteLine(dt.Rows.Count);

You might have not intended to do so, but I think you've managed to express the state of mind that a lot of individuals are in. The sense of wanting to assist, but not knowing how or where, is something a lot of us are going via.
