We ve now covered the major object model objects that you will use when working with lists in SharePoint 4, SharePoint Lists, has additional practical code examples of working with SharePoint lists
Working with Queries
Working with Queries
SPQuery The SPQuery object allows you to construct queries to return specific items in a list Commonly used properties and methods of SPQuery are shown in Table 3-13 We have already seen several methods that take an SPQuery and return an SPListItemCollection, including SPListGetItems and SPListGetDataTable
TABLE 3-13: Commonly Used Properties and Methods of SPQuery
Property or Method Query
Description Gets and sets the query in CAML This means you must know how to construct a query in CAML to use this object We will show some examples later in this section For a query on a document library, this property can set or get the folder used to restrict the query Gets and sets the columns that are returned by the query using a CAML expression Gets and sets a limit for the number of items that should be returned by a query Gets and sets additional parameters to the query in CAM, for example whether the scope of the query should include just files in a particular folder or should recursively include files in subfolders
Folder
ViewFields
RowLimit
ViewAttributes
The tricky thing with SPQuery is you have to come up with a Query string and the language the query is defined in is a SharePoint specific language called CAML collaborative application markup language It is beyond the scope of this book to completely describe CAML, but we will show you an example query and how it is used with SPQuery Another reason we don t describe CAML in depth is that with SharePoint 2010 you
3: Introduction to the SharePoint Object Model
can now use LINQ to create queries that we describe in 4, Working with SharePoint Lists CAML is constructed as a block of XML For example, to search our announcements lists for items with a title that contains the word Test, you would use a block of CAML This block orders the results by Title and finds items whose titles contain the word Test
             

Note the use of the XML element <Contains> This is an operator that tells SharePoint to find Titles that contain the word Test Other operators include <EQ> for equals, <NEQ> for not equal, <GT> for greater than, <GEQ> for greater than or equal, <LT> for lower than, <IsNull> for is null, and <BeginsWith> for begins with Listing 3-34 shows code in a web part that uses this CAML query string and places results in a table in a web part

SPSiteDataQuery The SPSiteDataQuery is like a powered up version of SPQuery it can execute a query across multiple lists in a site where SPQuery can only find items in one particular list The SPSiteDataQuery object is commonly used with the SPWeb object s GetSiteData method as a parameter that specifies the query to perform Commonly used properties and methods of the SPSiteDataQuery object are shown in Table 3-14
