Moss: What is the difference between spquery and spsitedataquery!

Source: Internet
Author: User

The following code is used to learn some object models of the developers who are developing moss and their views.
The usage of moss on spquery is about the small scope of the list query ..
Spweb = (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 is used to query the entire site, which is larger than spquery. I won't be able to pull it here. Let's take a look at the code and test it.
Spweb = (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 = 'cursive '/> ";
Query. viewfields = "<fieldref name = 'title'/> <projectproperty name = 'title'/> <listproperty name = 'title'/> ";
Datatable dt = web. getsitedata (query );
Console. writeline (Dt. Rows. Count );
Hope to help you !!!
