Gets or sets the inner XML that defines the query.
Namespace: Microsoft.SharePoint
Assembly: Microsoft.SharePoint (in Microsoft.SharePoint.dll)

Public Property Query As String

Set
'Usage
Dim instance As SPSiteDataQuery
Dim value As String
value = instance.Query
instance.Query = value
public string Query { get; set; }
Type: System.String
A string that contains a fragment in Collaborative Application Markup Language that defines the query.
The value of this property corresponds to the inner XML of the Query element in CAML, excluding the opening and closing <Query></Query> tags.
The Where element of the query string specifies the filter that determines which items are returned in the result set. The syntax is the same as the syntax used for the Query property of an SPQuery object.
The OrderBy element of the query string specifies the sort order of the items returned in the result set. The syntax is the same as the syntax used for the Query property of an SPQuery object, but in addition also supports the ListProperty and ProjectProperty subelements. For a description of these subelements, see the ViewFields property.
Items that do not contain a field that is referred to in Where or OrderBy elements of the query string are not included in the result set.
The following markup shows an example query string that has been formatted to make it easier to read.
<Where>
<Eq>
<FieldRef Name="AssignedTo"/>
<Value Type="Integer">
<UserID/>
</Value>
</Eq>
</Where>
<OrderBy>
<FieldRef Name="Priority"/>
<ProjectProperty Name="Title" />
<ListProperty Name="Title" />
</OrderBy>
The following example is a console application that queries all Tasks lists in a site collection. The query string selects tasks that are assigned to the current user, ordered by date due. After the results are returned, the application prints a report to the console.
